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 ESTIMATION OF COMBINING ABILITY AND GENE ACTION IN CHILLI(UHF Nauni, 2024-07-06) AKSHAY D A; Amit VikramThe present study titled “Estimation of Combining Ability and Gene Action in Chilli” was carried out during the Kharif, 2022 and 2023 at the Experimental Farm, Department of Vegetable Science, College of Horticulture, Dr YSPUH&F, Nauni-173 230, Solan (HP), India to study the information on the extent of mean performance, heterosis, combining ability, nature and magnitude of gene action for various horticultural traits. In experiment Ⅰ material consisted of 45 genotypes comprising of 9 diverse parents and 36 F1 hybrids developed from half diallel mating design. The genotypes were evaluated in a field trial conducted in Randomized Complete Block Design with three replications during Kharif, 2023. The observations were recorded on days to 50% flowering, plant height (cm), number of branches per plant, plant spread (cm), fruiting habit, days to ripe fruit maturity, pedicel length (cm), fruit length (cm), fruit width (mm), fruit weight (g), number of fruits per plant, fresh ripe fruit yield per plant (g), average dry fruit weight, dry weight recovery (%), dry fruit yield per plant (g), number of seeds per fruit, 1000 seed weight (g), capsaicin (%) and oleoresin (%). The analysis revealed that all the genotypes possessed wide spectrum of variability and showed significant differences for parents and hybrids for the traits under studied. The parents UHFCHI-10 (471.68g), C-9 (460.20g) and G-1-1 (414.75g) whereas, cross combinations Him Palam Mirch 2 × UHFCHI-10 (658.92 g), UHFCHI-10 × Anugraha (594.98 g), Him Palam Mirch 2 × G-1-1 (563.80 g) and UHFCHI-10 × G-1-1 (551.03) recorded the high fresh ripe fruit yield per plant. These hybrid combinations exhibited heterosis over check ranging from -8.98% (C-9 × Kullu Local) to 145.41% (Him Palam Mirch 2 × UHFCHI-10) and heterobeltiosis ranging from -46.89% (C-9 × Kullu Local) to 65.68% (UHFCHI-5 × DKC-8) for fresh ripe fruit yield per plant. For yield and component traits, the parental lines, UHFCHI-10 (61.83), G-1-1 (45.77) and Him Palam Mirch 2 (36.84) had exhibited good gca effect for fresh ripe fruit yield per plant. These genotypes with high gca can be used in multiple crosses and their segregating population can be used to develop superior recombinants. Among the cross combinations, the top five high yielding hybrid combinations with significant positive sca effects for fruit yield were G-1-1 × Kullu Local (131.57), Him Palam Mirch 2 × UHFCHI-10 (130.38), UHFCHI-5 × DKC-8 (124.93), C-9 × UHFCHI-12 (116.39) and UHFCHI-10 × Anugraha (98.29). Estimates of genetic variance revealed the preponderance of non-additive gene action for all the characters except plant height, number of branches per plant, fruit width, fruit weight, and 1000 seed weight where these traits were found to be governed by additive gene action. In experiment ⅠⅠ, two hybrid combinations used for generation mean analysis, Him Palam Mirch 2 × C-9 and UHFCHI-10 × G-1-1. Of the four traits under study, plant height, fruit length, width, and weight, dominance was predominant in both the crosses, some traits like fruit width and plant height showed additive gene action predominantlyThesisItem Open Access GENETIC ANALYSIS IN GARDEN PEA (Pisum sativum L.)(UHF Nauni, 2024-07-06) MUKESH KUMAR BAIRWA; Bhupinder Singh ThakurThe present study entitled, “Genetic Analysis in Garden Pea (Pisum sativum L.)” was carried out at the Experimental Research Farm, Regional Horticulture Research and Training Station, Bajaura, Kullu (HP) during Rabi seasons of 2021-22 and 2022-23. The experiment comprising of fifty-two genotypes was carried out in a Randomised Complete Block Design with three replications to elucidate the information on the extent of mean performance, heterosis, combining ability, nature and magnitude of gene action for different horticultural traits in garden pea. Inheritance of resistance to powdery mildew in garden pea was also studied through reaction of different generations (F2, B1 and B2) to powdery mildew using chi-square analysis. The analysis of variance showed highly significant differences among all the genotypes for all the traits. Based on mean performance parents viz., PB-89, Arkel and Baj-Pea-12, and cross combinations Baj-Pea-7 × PB-89 and Baj-Pea-12 × PB-89 were found to be the best performers whereas cross combinations viz., Baj-Pea-3 × PB-89, Baj-Pea-3 × Arkel and Baj-Pea-7 × PB-89 were observed to give best heterotic performance for days to 50 per cent flowering over standard check (Azad Pea-1). The experiment results revealed that four parent namely Baj-Pea-12, Baj-Pea-11, Baj-Pea-8 and PB-89 gave overall best mean performance for traits studied and their GCA effects also indicated towards their contribution towards high heterosis for pod yield and other characters which was clearly indicated through best heterotic cross combinations viz., Baj-Pea-12 × PB-89, Baj-Pea-12 × Lincoln, Baj-Pea-8 × Lincoln, Baj-Pea-7 × PB-89 and Baj-Pea-11 × PB-89). Hence, theses crosses can be helpful in isolating desirable transgressive segregants and could be utilized for future garden pea breeding programme The severity of powdery mildew was also observed to be minimum in Baj-Pea-12, Baj-Pea-11 and Baj-Pea-8 among the parents, and among the crosses, combinations viz., Baj-Pea-11× PB-89, Baj-Pea-12 × PB-89, Baj-Pea-8 × PB-89 and Baj-Pea-12 × Arkel had low incidence of powdery mildew. Gene action studies indicated the predominance of additive variance for all the traits. Chi-square analysis revealed that a single recessive gene is responsible for conferring resistance to powdery mildew. The pattern of inheritance for powdery mildew resistance was governed by a single recessive gene the F2 generation revealed a 1:3 ratio for resistance: susceptible plant.ThesisItem Open Access Studies on effect of intercropping and manurial practices on pod and seed yield of French bean cv. Lakshmi(UHF Nauni, 2023-12-05) NANDINI SHARMA; Dr H Dev SharmaThe present investigation entitled “Studies on effect of intercropping and manurial practices on pod and seed yield of French bean cv. Lakshmi” was carried out at Experimental Farm and Quality Analysis Laboratory, Department of Vegetable Science, Dr Yashwant Singh Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) during Kharif 2022. The experiment was conducted on main crop French bean cv. Lakshmi and intercrops viz., maize var. Local Selection and okra var. P-8 which was laid out in Randomized Complete Block Design with three replications, comprising of seven treatments viz., T1: French bean intercropped with Maize + FYM, T2: French bean intercropped with Maize + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T3: French bean intercropped with Maize + FYM + RDF, T4: French bean intercropped with Okra + FYM, T5: French bean intercropped with Okra + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T6: French bean intercropped with Okra + FYM + RDF and T7 (Control): French bean sole crop + FYM + RDF. Analysis of variance showed significant variations for effect of intercropping and manurial practices on most of the parameters studied. Among different treatments, sole French bean + FYM + RDF (T7) recorded minimum days to 50 % flowering and days to first maturity and maximum number of clusters per plant, number of pods per plant, pod length, pod width, number of seeds per pod, plant height, pod and seed yield (per plant & per hectare), 100 seed weight and protein content. T6 performed best in yield of intercrops, and total French bean pod plus French bean pod equivalent yield as well as total French bean seed plus French bean seed equivalent yield (per plant & per hectare). From the present investigation, it was concluded that French bean cv. Lakshmi intercropped with okra and application of recommended doses of manures and fertilizers (200 q/ha FYM + 50 kg N/ha + 100 kg P2O5/ha + 50 kg K2O/ha) gave the highest yield of French bean pod (109.97 q/ha) and okra (110.18 q/ha) along with maximum net returns per hectare (₹ 4,47,493) and B:C ratio (2.10) and for seed production, it gave the highest seed yield of French bean (11.17 q/ha) and okra (110.18 q/ha) along with maximum net returns per hectare (₹ 4,48,443) and B:C ratio (2.06) under mid hill conditions of Himachal Pradesh.ThesisItem Open Access HETEROSIS AND COMBINING ABILITY OF OKRA (Abelmoschus esculentus (L.) Moench) UNDER LOW HILL CONDITIONS OF HIMACHAL PRADESH(UHF Nauni, 2024-03-04) PRATIBHA SHARMA; BS DograThe present studies entitled "Heterosis and combining ability of okra (Abelnoschus esculentus (L.) Moench) under low hill conditions of Himachal Pradesh" were carried out at the Experimental Research Farm of the Department of Vegetable Science, College of Horticulture and Forestry, Dr YS Parmar University of Horticulture and Forestry, Neri, Hamirpur, Himachal Pradesh during the years 2021 and 2022. The experimental material for the present study comprised of eight parents and F1 population of twenty-eight crosses, developed by crossing these eight diverse okra lines in diallel design (excluding reciprocals). All the parents and their hybrids along with the standard check (Punjab-8) were planted in a Randomized Complete Block Design for their evaluation in Kharif, 2022. The observations were recorded on yield and yield related traits viz., germination period, days to 50 per cent flowering, first fruiting node, internodal length (cm), number of primary branches per plant, pod length (cm), pod diameter (cm), number of locules per pod, number of pods per plant, average pod weight (g), pod yield per plant (g), days to first picking, harvest duration, plant height (cm), number of seeds per pod and 100 seed weight (g). The analysis of variance indicated highly significant diferences among the genotypes for all the traits studied. Experimental results revealed that three lines viz., Pusa Sawani, Pusa A-4 and Parbhani Kranti were found superior on the basis of mean performance and general combining ability studies. Three cross combinations viz., Parbhani Kranti x Punjab-8, Pusa A-4 x Pusa Sawani and Pusa Sawanix Arka Anamika were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further. Gene action studies indicated predominance of dominance elfets in goveming most of the traits suggesting exploitation of hybrid vigour and developing hybrids for unprovement of these traits in okra on the basis of present studies.ThesisItem Open Access EFFECT OF CROP INTENSIFICATION IN TOMATO GROWN UNDER NATURAL FARMING SYSTEM(UHF Nauni, 2023-11-06) UJJWAL RAJ; Kuldeep Singh ThakurThe present investigation entitled “Effect of crop intensification in tomato grown under natural farming system” was carried out at the Subhash Palekar Model Farm, Department of Entomology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif season of 2023. The experiment was laid out in Randomized Complete Block Design (Factorial) with three replications comprising of twelve treatment combinations. The treatments were G0J0: No Ghanjeevamrit + No Jeevamrit (control), G0J1: No Ghanjeevamrit + Jeevamrit spray @ 10 %, G0J2: No Ghanjeevamrit + Jeevamrit spray @ 15 %, G0J3: No Ghanjeevamrit + Jeevamrit spray @ 20 %, G1J0: Ghanjeevamrit @ 1 t/ha + No Jeevamrit, G1J1: Ghanjeevamrit @ 1 t/ha + Jeevamrit spray @ 10 %, G1J2: Ghanjeevamrit @ 1 t/ha + Jeevamrit spray @ 15 %, G1J3: Ghanjeevamrit @ 1 t/ha + Jeevamrit spray @ 20 %, G2J0: Ghanjeevamrit @ 1.5 t/ha + No Jeevamrit, G2J1: Ghanjeevamrit @ 1.5 t/ha + Jeevamrit spray @ 10 %, G2J2 :Ghanjeevamrit @ 1.5 t/ha + Jeevamrit spray @ 15 %, G2J3: Ghanjeevamrit @ 1.5 t/ha + Jeevamrit spray @ 20 %. The main crop (tomato) variety was ‘Solan Lalima’. The intercrops were French bean cv. ‘Contender’ and brinjal cv. ‘Pusa Purple Long’. Each plot size was 5.4 m2 having five rows of tomato at the spacing of 90 × 30 cm and four rows of intercrops were also sown in the centre of tomato crop. The seeds of tomato and brinjal were sown in the nursery beds on 3rd March, 2023 and the seedlings were transplanted on 15th April, 2023.The seeds of French bean was shown after 2 days of transplanting of main crop. The combined application of ghanjeevamrit @ 1.5t/ha along with jeevamrit spray @ 15 per cent (G2J2) resulted in maximum plant height, harvest duration, number of fruits per cluster, number of fruits per plant, fruit yield per plant, yield per plot and per hectare, organic carbon, NPK content, viable microbial count and highest net returns. Hence, application of ghanjeevamrit @ 1.5 t/ha + jeevamrit spray @ 15 per cent at 15 days interval can be recommended for getting high yield, enhanced soil fertility and maximum net returns in tomato under natural farming condition.ThesisItem Open Access MORPHOLOGICAL CHARACTERIZATION AND DISEASE REACTION STUDIES IN BELL PEPPER(UHF Nauni, 2023-11-02) GURPREET KAUR; D.K.MehtaThe present investigation entitled “Morphological Characterization and Disease Reaction Studies in Bell Pepper” was carried out at the Experimental Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2022. Thirty-four advanced breeding lines/ genotypes of bell pepper along with two standard check varieties (California Wonder and Solan Bharpur) were evaluated for morphological characters based on DUS along with analysis of various horticultural traits and disease reaction to Phytophthora leaf blight and fruit rot. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications and the genotypes were morphologically classified based on forty-two DUS traits. Analysis of variance for horticultural traits revealed significant differences among all the genotypes for most of the characters under study. Genotypes UHF-CAP-108, UHF-CAP-119, IIHR-131, UHF-CAP-106 and UHF-CAP-113 were found to be significantly superior than the better check variety i.e., Solan Bharpur for fruit yield per plant with desirable medium sized, dark green, glossy and 3-4 lobed fruits. Hence, these genotypes should be tested in multi-locational and multi-year trials so that the most superior and stable genotype(s) can be recommended for commercial cultivation.

Among various parameters of variability, fruit yield per plant, number of fruits per plant and fruit weight had high values of coefficients of variation as well as high heritability coupled with high genetic gain indicating the prevalence of additive gene action. Correlation coefficient depicted that number of fruits per plant, fruit weight, number of lobes per fruit, internodal length, pericarp thickness, plant height, plant spread, leaf area, leaf length and leaf width were significantly and positively correlated with fruit yield per plant. Thus, selection of genotypes on the basis of these traits would be effective in improving fruit yield per plant. The maximum positive direct effect on fruit yield per plant was contributed by number of fruits per plant followed by fruit weight, leaf area, plant height, pericarp thickness and thousand seed weight. Thus, improvement in these characters will lead to higher fruit yield per plant in bell pepper. Genetic divergence studies revealed that hybridization between genotypes of cluster IV and VI will be more rewarding for getting superior hybrids. In case of disease reaction studies, no genotype was found to be resistant to Phytophthora leaf blight and fruit rot but moderate susceptibility was found in genotypes UHF-CAP-104, UHF-CAP-107, UHF-CAP-111, UHF-CAP-116, UHF-CAP-119, UHF-CAP-127, IIHR-131 and check variety Solan BharpurThe present investigation entitled “Morphological Characterization and Disease Reaction Studies in Bell Pepper” was carried out at the Experimental Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2022.

The present investigation entitled “Genetic variability studies in tomato” was carried out at the Vegetable Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Solan (HP) during Kharif, 2022. Thirty genotypes including check variety Solan Lalima were evaluated to ascertain the extent of variability, correlation and path analysis for yield and other horticultural traits along with estimation of genetic gain among genotypes. The experiment was laid out in Randomized Block Design with three replications. The present studies revealed significant variation among genotypes for all the traits. Where, it is recorded that SEL-26, SEL-22 and CLW-2174102 have performed superior over the check in various attributes. High genetic variability was recorded for fruit yield per plant and number of fruits per cluster. Followed by, moderate genetic variability was recorded for average fruit weight, plant height, number of locules per fruit, number of fruits per plant, number of seeds per fruit, pericarp thickness and fruit shape index. While low genetic variability was recorded for total soluble solids, days to 50% flowering, harvest duration and days to maturity. Fruit yield per plant was significantly and positively correlated with average fruit weight followed by number of fruits per plant, days to 50% flowering, days to maturity, plant height, fruit shape index, number of locules per fruit and harvest duration.

Thirty-five genotypes of garlic along with one check variety (Solan Selection) were evaluated for morphological characters based on DUS along with analysis of various horticultural traits. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications and the genotypes were morphologically classified based on thirty- one DUS characters. Analysis of variance for horticultural traits revealed significant differences among all the genotypes for most of the characters under study. Genotype LGC-20 performed best in terms of yield and other horticultural traits closely followed by LGC-2, LGC-22 and LGC-15. These genotypes were significantly superior than the check variety i.e., Solan Selection for bulb yield along with number of cloves per bulb, bulb equatorial and polar diameter, clove weight and clove size. Hence, these genotypes should be tested in multi-locational and multi-year trials so that the most superior and stable genotype(s) can be recommended for commercial cultivation. Among various parameters of variability, bulb weight, clove weight and pseudostem width and leaf width had high values of coefficients of variation as well as high heritability coupled with high genetic gain indicating the prevalence of additive gene action. Correlation coefficient depicted that number of cloves, clove weight, clove size, clove diameter,bulb equatorial and polar diameter, number of leaves per pseudotstem, leaf length, leaf width, pseudostem length, days to maturity and pseudostem width were significantly and positively correlated with bulb weight. Thus, selection of genotypes on the basis of these traits would be effective in improving bulb yield. The maximum positive direct effect on bulb weight was contributed by bulb equatorial diameter followed by pseudostem width, number of cloves, bulb polar diameter, days to maturity, clove diameter, clove weight and leaf length. Thus, improvement in these characters will lead to higher bulb weight in garlic. Genetic divergence studies revealed that hybridization between genotypes of cluster II and IV will be more rewarding for getting superior genotypes.ThesisItem Open Access STUDIES ON GINGER BASED INTERCROPPING SYSTEMS FOR HIGHER YIELD AND INCOME(UHF Nauni, 2023-12-05) MUSKAN SHARMA; Vipin SharmaThe present investigation entitled, “Studies on ginger based intercropping systems for higher yield and income” was carried out in Randomized Complete Block Design with three replications in plot size of 3 m × 1 m and spacing 30 cm × 20 cm at Vegetable Research Farm and Quality Analysis Laboratory of the Department of Vegetable Science, Dr YSPUHF, Nauni, Solan (HP) during Kharif 2022.
