Dr. Y. S. Parmar University of Horticulture & Forestry, Solan
Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry.
The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services.
The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

ThesisItem Open Access Genetic studies on yield and quality traits in cucumber (Cucumis sativusL.)(DYSPU, 2013) Sandeep Kumar; Ramesh KumarThe present studies entitled “Genetic studies on yield and quality traits in cucumber (Cucumis sativus L.)” were carried out at the Experimental Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2011 and 2012. The experimental material for the present study comprised of F 1 population of forty eight crosses, developed by crossing 16 lines and 3 testers. All the parents (16 lines and 3 testers) and their hybrids (48) along with the standard checks (KH-1 and Pusa Sanyog) were planted in a Randomized Complete Block Design for their comparative evaluation. The observations wererecorded on days to first female flower appearance, node number bearing first female flower, days to marketable maturity, fruit length (cm), fruit breadth (cm), average fruit weight (g), fruit colour, number of marketable fruits per plant, harvest duration (days), marketable yield per plot (kg) & per hectare (q), total soluble solids ( o B), cucurbitacin content (µg/100g), incidence of fruit fly (%), severity of powdery mildew (%), downy mildew (%) and angular leaf spot (%), seed germination (%) and seed vigour index-I and II. The analysis of variance indicated highly significant differences among the genotypes for all the traits studied. Experimental results revealed that five lines viz.,LC-1-1, CGN-20953, LC-2-2, CGN-19533 and Gyne-5 and two testers viz., K-75 and Poinsette were found superior on the basisof mean performance and general combining ability studies. Five cross combination viz., LC-1-1 x K-75, LC-2-2 x Poinsette, CGN-19533 x K-75, Gyne-5 x K-75 and CGN-20953 x Poinsette were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further at multilocations before releasing as a substitute of already exiting hybrid varieties of cucumber in Himachal Pradesh and in India as well.ThesisItem Open Access Heterosis, combining ability and gene action studies in tomato (Solanum lycopersicum L.)(YSPU, 2014) Gautam, NidhishThe present studies entitled “Heterosis, combining ability and gene action studies in tomato (Solanum lycopersicum L.)” were carried out at the Experimental Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2012 and 2013. The experimental material for the present study comprised of six parents and F1 population of fifteen crosses, developed by crossing these six diverse tomato lines in diallel design (excluding reciprocals). All the parents and their hybrids along with the standard check (Naveen) were planted in a Randomized Complete Block Design for their evaluation in Kharif, 2013. The observations were recorded on days to first flowering, days to marketable maturity, average fruit weight (g), number of fruits per plant, harvest duration (days), fruit yield (kg/plant, kg/plot and q/ha), plant height (cm), number of locules per fruit, pericarp thickness (mm), whole fruit firmness (g/0.503cm2), total soluble solids (oBrix), ascorbic acid content (mg/100g), lycopene content (mg/100g), buckeye rot incidence (%) and Alternaria blight severity (%). The analysis of variance indicated highly significant differences among the genotypes for all the traits studied. Experimental results revealed that three lines viz., Solan Lalima, UHFT-9 and UHFT-10 were found superior on the basis of mean performance and general combining ability studies. Five cross combinations viz., UHFT-9 x Solan Lalima, UHFT-10 x Solan Lalima, UHFT-55 x Solan Lalima, UHFT-22 x Solan Lalima and UHFT-9 x UHFT-10 were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further at multiplications before releasing as a substitute of already existing hybrid varieties of tomato in Himachal Pradesh and in India as well. Gene action studies indicated predominance of dominance effects in governing most of the traits suggesting exploitation of hybrid vigour and developing hybrids for improvement of these traits in tomato on the basis of present studies.ThesisItem Open Access Genetic studies for yield and quality traits in tomato (Solanum lycopersicumL.)(YSPU, 2016) Rakesh; Sharma, Hem RajThe present investigation entitled “Genetic studies for yield and quality traits in tomato (Solanum lycopersicum L.)” was carried out at the Experimental Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2014-15 and 2015-16 to know the extent of heterosis, assessing combining ability and generating information on gene action. Six diverse tomato genotypes were crossed in a diallelb fashion (excluding reciprocals) during Kharif2014-15 and in the next year fifteen crosses alongwith 6 parents and one standard check (Naveen 2000+) were evaluated in RCBD. Analysis of variance showed significant differences among all the genotypes for all the characters under study. The genotypes, EC-1055 and EC-1057 among parents while Solan Lalima x EC-1057 and Solan Lalima x EC-1058 among cross combinations were found superior for earliness. Heterobeltiosis for fruit yield and quality traits was recorded significantlypositive in Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058. Maximum negative heterosis for buck eye rot incidence and alternaria blight severity was observed in Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058. For yield and component traits Solan Lalima was good general combiner. Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were good specific combiners for fruit clusters per plant, number of fruits per cluster, number of fruits per plant, harvest duration and fruit yield traits. Solan Lalima and UHF-55 were good general combiners for total soluble solids, lycopene content and ascorbic acid content. Cross combinations viz.Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were good specific combiners for all quality traits. Solan Lalima was good general combiner for buck eye rot incidence, alternaria leaf blight severity, septoria leaf blight severity and fruit borer infestation. The estimates of σ 2 g/σ 2 s (predictability ratio) were found to be < 1 for almost all the traits included in this study except for plant height, fruit size, buck eye rot incidence and fruit borer infestation indicated predominance of non additive gene action.ThesisItem Open Access Response of tomato genotypes to different mulches and biofertilizers(DYSPU, 2013) Sandeep Kumar Singh; Sharma, Hem RajThe present study entitled “Response of tomato genotypes to different mulches and biofertilizers” was carried out at the experimental farm of Horticulture Research Station, Kandaghat, Dr Y S Parmar U H F, Solan, Himachal Pradesh, during 2011 and 2012. The experiment comprised of three genotypes (V 1 -Naveen 2000 + , V2-Sun-7711 and V3-Solan Lalima), three mulches (M0-No mulch, M1-Pine needle mulch and M 2- black polyethylene) and three biofertilizers (B0-recommended NPK, B1-100 % NPK + Azotobacter(1g/plant) + PSB (1g/plant) and B2-75 % NPK + Azotobacter(1g/plant) + PSB (1g/plant). Thus, there were 27 treatment combinations which were replicated thrice in Split-Split Plot Design. The observations were recorded on number of days to first flowering, number of days to first harvest, harvest duration, number of fruits/plant, average fruit weight (g), fruit length (cm), fruit width (cm), plantheight (m), yield (kg/plant), yield (kg/plot), yield (q/ha), pericarp thickness (mm), TSS ( 0 Brix), acidity (%), shelf life (days), fruit firmness (g per 0.503cm 2 ) ascorbic acid (mg/100g), lycopene content (mg/100g), incidence of buckeye rot (%), severity of bacterial leaf spot (%), early blight (%), septoria blight (%) available nitrogen (kg/ha), phosphorus (kg/ha), potash (kg/ha), organic carbon (%), pH and electrical conduvtivity. Among varieties, maximum yield was observed with the variety V2(Sun-7711), but the fruit quality characters as well as the ability to resistdisease incidence/severity was observed with the variety V3(Solan Lalima). Among the mulch materials the M2 (Black polythene) and biofertilizers B1 (100% NPK + Azotobacter(1g/plant) + PSB (1g/plant) were recorded to be the best regarding the fruit yield, quality and soil nutrient status as well as disease incidence/severity. The first order interactions viz., varieties x mulch, biofertilizers x mulch and varieties x biofertilizers significantly affected most of the characters under study. Maximum fruit yield was obtained with treatment combinations of V2M2 (Sun-7711 applied with black polyethylene mulch), B2M2(75% NPK + Azotobacter(1g/plant) + PSB (1g/plant) applied with black polyethylene mulch) and V 2B2(Sun-7711with 75 % NPK + Azotobacter(1g/plant) + PSB (1g/plant). Further in three factor interaction, the highest fruit yield (1037.33 q/ha) with maximum net returns (Rs. 436059.51) and highest cost benefit ratio (1:5.28) was obtained with the treatment combination of Sun-7711, 75% NPK + Azotobacter(1g/plant) + PSB (1g/plant) and black polyethylenemulch (V2B2M2).ThesisItem Open Access Comparative efficiency of organic, inorganic and integrated nutrient management on growth, yield and quality of sprouting broccoli (Brassica oleracea L. var. italica) cv. Green Head(YSPU, 2014) Prince Kumar; Bhardwaj, M.L.The present investigations entitled "Comparative efficiency of organic, inorganic and integrated nutrient management on growth, yield and uality of sprouting broccoli (Brassica oleracea L var italica Plenck) cv. Green Head" was carried our during rabi season of 2011- 12 and 2012-13 in the Experimental Farm of the Department of Vegetable Science, 1)1' Y S Parmar University of Horticulture and Forestry, Nanni, Solan (HP). Twenty five treatments combinations of inorganic (N, P and K), organic verrnicornposr, neern manure and FYM) and biofertilizers (Azotobacter and PSB) were replicated thrice in a plot having dimensions of 3.00 m x 2.70 In The experiment was laid out in a randomized complete block design and a spacing of 60 Clll x 45 em was followed Seed of sprouting broccoli cv. Green Head was sown in the nursery bed on 2nd week of September, 2011 and 2012. One month old seedlings were transplanted on 2nd week of October during both the years. The data were recorded 011 days taken to 50 per cent heading, plant height at maturity (ern), number of leaves per plant, head size (ern"), average head weight (g), number of marketable secondary heads/plant, average secondary head weight (g), yield pel' plot (kg) and per hectare (q), severity of black rot (%), vitamin A (I U), vitamin C (mgllOOg), protein (0/" by weight): uptake of N:P,K and micronutrient, (Zn, Cu, Mn, Fe), available N,P.K content in the soil before and after harvest and benefit: cost ratio. The results revealed that recommended dose of fertilizers + Azotobacter (5kglha) + PSB (5kglha) was rated as the best treatment (TI6) for characters like head size (em), average head weight (g), number of marketable secondary heads/plant, average secondary head weight (g), yield per plot (kg) and pel' hectare (q) and benefit: cost ratio followed by T2L i.e .. recommended dose of fertilizers (33.3 %) + FYM (33.3 %) + VC (33..3 %) + Azotobacter (5.0 kg/ha) + PSB (5.0 kg/ha) for characters like days taken to 50 per cent heading, plant height at maturity (em), number of leaves per plant, severity of black rot (%), vitamin A (I U), vitamin C (mglIOOg), protein (% by weight), uptake of N,P,K and micronurrients (Zn, Cu, Mn, Fe), available N,P,K content in the soil before and after harvest consistently during both the years. However, minimum values for all the characters studied were recorded by sole application of different organic manures and biofertilizers. It was concluded that integration of bioferti lizers, organic manures and reduced level of inorganic fertilizers gave better results and hence, there is a great scope of improvement in growth, yield, and quality of sprouting broccoli.ThesisItem Open Access GENETIC DIVERGENCE STUDIES IN TOMATO (Solanum lycopersicumL.)(UHF,NAUNI, 2015) RAI, AMARJEET KUMAR; AMIT, VIKRAMABSTRACT Tomato (Solanum lycopersicum L.) is one of the most important warm season fruit vegetable widely produced and consumed in the world both for fresh market and for processed food industries. The present investigation entitled “Genetic divergence studies in tomato (Solanum lycopersicum L.),” was carried out at the Vegetable Research Farm, Department of Vegetable Science, Dr. Y. S. Parmar University of Horticulture and Forestry, Solan (HP) during Kharif, 2014. Fifty-six genotypes including check variety Solan Lalima were evaluated to ascertain the extent of variability, correlation and path analysis for yield and other horticultural traits alongwith estimation of genetic divergence among genotypes. The experiment was laid out in Randomized Complete Block Design with three replications. The present studies revealed significant variation among genotypes for all the traits. A wide range of variability was observed for all the traits. High genetic variability was recorded for number of fruits per plant, average fruit weight, lycopene content and yield per plant while low genetic variability was recorded for days to first picking. High estimates of heritability and high genetic gain was recorded for number of fruits per plant, average fruit weight, lycopene content, locular wall thickness and yield per plant indicating possibility of their effective selection. Fruit yield per plant was significantly and positively correlated with average fruit weight, plant height, inter-nodal distance, pericarp thickness and locular wall thickness. Path analysis revealed that average fruit weight followed by number of fruits per plant had maximum positive direct effect towards fruit yield per plant. Genetic divergence studies revealed that hybridization between genotypes of cluster IV and V would be more rewarding for getting superior progeny.ThesisItem Open Access STUDIES ON GENETIC VARIABILITY IN TOMATO (Solanum lycopersicumL.) GENOTYPES FOR DIFFERENT HORTICULTURAL TRAITS(UHF,NAUNI, 2014) NITISH, KUMAR; BHARDWAJ, M.L.ABSTRACT The present investigations entitled “Studies on genetic variability in tomato (Solanum lycopersicum L.) genotypes for different horticultural traits” was carried out at the Research Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during Kharif, 2013 to evaluate diverse germplasm of tomato. The experiment was laid out in a RCBD with three replications. In this study, thirty five genotypes including one check cultivar were evaluated for different horticultural traits. The observations were recorded on days to 50% flowering, number of fruits per cluster, number of fruits per plant, average fruit weight (g), fruit yield per plant (kg), fruit yield per plot (kg), fruit yield per hectare (q), fruit shape index, number of locules per fruit, pericarp thickness (mm), plant height (cm), harvest duration (days), days to marketable maturity, total soluble solids ( o B), ascorbic acid content (mg/100g), fruit colour, buckeye rot incidence (%) and alternaria blight severity (%). Analysis of variance showed significant differences among genotypes for all the characters under study. The genotypes JTS-10-1, JTS-10-2, Yalabingo, EC-37239, EC-267727, LE-79-5, BT-10, EC-191535-3 and JTS-1-1 gave highest fruit yield. High phenotypic and genotypic coefficients of variation were depicted for the character like number of fruits per plant, fruit yieldper plant, fruit yield per plot, fruit yield per hectare and plant height. High heritability coupled with high genetic gain were recorded for number of fruits per plant, plant height, average fruit weight and fruit yield per plant,per plot and per hectare. Hence selection can prove effective for improvement in yield. High heritability coupled with moderate genetic gain was observed for number of fruits per cluster, harvest duration and ascorbic acid content. Therefore, these characters also show some scope for improvement through selection. A highly significant and positive phenotypic and genotypic correlation of fruit yield per plant was observed with plant height,number of fruits per plant, harvest duration, number of fruits per cluster, total soluble solids and average fruit weight. Maximum positive direct effect towards fruit yield per plant was contributed by number of fruits per plant followed by harvest duration and average fruit weight. The maximum negative direct effect towards yield was recorded by days to marketable maturity. Further, these genotypes were grouped into four divergent clusters and hybridization between cluster I and IV gives maximum heterotic combinations.ThesisItem Open Access STUDIES ON GENETIC DIVERGENCE IN BELL PEPPER (Capsicum annuum L. var. grossum)(UHF,NAUNI, 2014) SHARMA, ANKITA; MANISH, KUMARABSTRACT The present investigations entitled “Studies on genetic divergence in bell pepper (Capsicum annuum L. var. grossum)” was carried out at the Research Farm, Departmentof Vegetable Science, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during Kharif, 2013 to evaluate germplasm of bell pepper and to study variability, heritability, correlation and path analysis of different characters along with estimation of genetic divergence among genotypes. The experiment was laid out in a RCBD with three replications. In this study, thirty five genotypes including three check cultivars were evaluated for different horticultural traits. The observations were recorded on days to first flowering, days to first marketable picking, number of fruits per plant, fruit length (cm), fruit breadth (cm), average fruit weight (g), pericarp thickness (mm), plant height (cm), harvest duration (days), number of seeds per fruit, number of lobes per fruit, ascorbic acid content (mg/100g), capsaicin content (mg/g), fruit yield (kg/plant, kg/plot and q/ha), Phythophthora fruit rot incidence (%) and Phytophthora leaf blight severity (%). Analysis of variance showed significant differences among all the genotypes for all the characters under study. The genotype DARL-72 gave higher yield and performed better for other important horticultural traits over all the checks and also showed tolerance to Phytophthora leaf blight and fruit rotdisease. High heritability coupled with high genetic gain was obtained for fruit yield. Hence, selectioncan prove effective for improvement in fruit yield. High heritability coupled with moderate genetic gain was obtained for number of fruits per plant, average fruit weight and pericarp thickness indicating some scope for their improvement through selection. A highly significant and positive phenotypic and genotypic correlation of yield was found with number of fruits per plant, fruit length, fruit breadth, average fruit weight, pericarp thickness, plant height, harvest duration and number of lobes per fruit. Maximum positive direct effect towards yield were contributed by number of fruits per plant, followed by average fruit weight and pericarp thickness. In the present investigations the cluster III and IV were found most divergent and there will be more chances of getting better segregants in F 2and subsequent generations from the crossing of genotypes between cluster III and IV.ThesisItem Open Access STUDIES ON GENETIC VARIABILITY IN OKRA (Abelmoschus esculentus(L.) Moench)(UHF,NAUNI, 2014) RAGHVENDRA, KUMAR; BHARDWAJ, M.L.ABSTRACT The present investigations entitled “Studies on genetic variability in okra (Abelmoschus esculentus (L.) Moench)” were carried out at the Experimental Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif,2013 to evaluate diverse germplasm of okra. The experiment was laid out in a RCBD with three replications. Thirty six genotypes including check cultivars were evaluated for different horticultural traits. The observations were recorded on days to 50% flowering, first fruiting node, internodal length, plant height, fruit length, fruit diameter, fruit weight, number of fruits per plant, number of ridges per fruit, number of seeds per fruit, 1000 seed weight, fruit yieldper plant, fruit yield per hectare, incidence of fruit borer and severity of phytophthora blight. Analysis of variance showed significant differences among all the genotypes forall the characters studied. Genotypes LC-13, VRO-3, NS-29, LC-11, IC 58235 and IC 212267 gave higher yield and also performed better for other horticultural traitsunder mid hills conditions of Himachal Pradesh. The phenotypic and genotypic coefficients of variation were recorded high for internodal length and number of seeds per fruit. High heritability coupled with high geneticgain was observed for the characters like internodal length,number of fruits per plant and fruit yield per plant. Significant positive genotypic and phenotypic correlation of yield was found with number of fruits per plant, fruit weight and harvest duration, whereas, significant negativegenotypic and phenotypic correlations were found with days to 50% flowering, first fruiting node, internodal length and days to first harvest. Further, these genotypes were grouped into five divergent clusters and hybridization between cluster I and V gives maximum heterotic combinations.
