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.

    LINE × TESTER ANALYSIS FOR HORTICULTURAL TRAITS IN WHITE FRUITED BRINJAL (Solanum melongena L.)
    (UHF,NAUNI, 2021-05) ANNEPU, SUDHEER KUMAR; SHARMA, H DEV
    ABSTRACT The present study entitled “Line × Tester analysis for horticultural traits in white fruited brinjal (Solanum melongena L.)” was carried out during the Kharif, 2019 and 2020 at the Experimental Farm, Department of Vegetable Science, College of Horticulture, Dr YSPUH&F, Nauni-173 230, Solan (HP), India to elucidate the information on the extent of mean performance, heterosis, combining ability, nature and magnitude of gene action for various horticultural traits. The experimental material consisted of 35 genotypes comprising of eight diverse lines, three testers, 24 F1 hybrids resulted from employing Line × Tester mating design. The genotypes were evaluated in a field trial conducted in Randomized Block Design with three replications during Kharif, 2020. The observations were recorded on days to 50% flowering, days to first picking, number of fruits per plant, fruit length (cm), fruit breadth (cm), fruit weight (g), number of leaves per plant, plant height (cm), number of primary branches per plant, stem girth (cm), fruit yield per plant (g), projected fruit yield per hectare (q/ha), infestation of shoot and fruit borer (%), incidence of fruit rot (%), TSS (ºB), ascorbic acid content (mg/100g), total phenol content (mg/100g) and antioxidant activity (μmol TE/g FW). Further, 30 different SRAP marker combinations were used to determine the molecular diversity among the parental genotypes used in the hybridization programme. The Line × Tester analysis revealed that all the genotypes possessed wide spectrum of variability and showed significant differences for lines, testers and line × tester interaction for majority of the traits studied. The white fruited brinjal varieties, Indira Safed Bangan (297.03 q/ha) followed by KKM-1 (252.82 q/ha), Kashi Himani (249.73 q/ha) and Shweta (242.24 q/ha) whereas, cross combinations KKM-1 × Kashi Himani (397.40 q/ha), Nadia Local × Kashi Himani (392.41 q/ha), IC-090696 × Indira Safed Bangan (389.23 q/ha) and IC-090696 × Shweta (354.52 q/ha) recorded the high fruit yield. These hybrid combinations exhibited mid parent heterosis ranging from 58.15% (KKM-1 × Kashi Himani) to 79.27% (Nadia Local × Kashi Himani) and heterobeltiosis ranging from 31.04% (IC-090696 × Indira Safed Bangan) to 57.19% (KKM-1 × Kashi Himani) for fruit yield. For yield and component traits, the parental lines viz., IC-090696, KKM-1, EC-169089 and Nadia Local had exerted good GCA effects whereas, Kashi Himani is the tester genotype with good GCA effect for fruit yield. These genotypes with high GCA can be used in multiple crosses and their segregating population. Among the cross combinations, the top four high yielding hybrid combinations with significant positive SCA effects for fruit yield are Nadia Local × Kashi Himani (186.69), IC-112901 × Kashi Himani (132.78), KKM-1 × Kashi Himani (112.40) and IC-090696 × Shweta (114.01). The genetic diversity studies using SRAP markers revealed that, among the 30 SRAP primer combinations, 25 primer combinations were found to be polymorphic thus, appeared to be useful to elucidate the molecular diversity in the parental genotypes. The number of band position generated by these thirty markers for all the 11 parental genotypes were 101, which gave an average of 3.36 alleles per marker. The dendrogram constructed from SRAP marker data divided eleven parental genotypes into three clusters. The molecular diversity analysis carried out during the present investigation proved that, SRAP markers could be efficiently applied to detect polymorphism even with a relatively low number of alleles.

    EFFECT OF DIFFERENT SPENT MUSHROOM SUBSTRATES AND OTHER NUTRIENT SOURCES ON GROWTH YIELD AND QUALITY OF PEA (Pisum sativum L.)
    (UHF,NAUNI, 2021-05) THAKUR, SHIVENDER; THAKUR, KUDEEP SINGH
    ABSTRACT The present study entitled “Effect of different spent mushroom substrates and other nutrient sources on growth, yield and quality of pea (Pisum sativum L.)” was carried out at the Experimental Farm, Department of Vegetable Science, College of Horticulture, Dr YS Parmar University of Horticulture and Forestry, Nauni Solan, (HP) in two successive seasons i.e. rabi 2018-19 and 2019-20. The experiment was laid out in Randomised Complete Block Design with three replications comprising of thirteen treatment combinations of inorganic fertilizer, different spent mushroom substrates (button, shitake and oyster mushroom spent substrates) and biofertilizers (PSB, RZB) inoculation through seed and soil application. The treatments were T1: RPF: RDF- (N 25: P 60: K 60) + FYM 20t/ha, T2: 80 % RDF + 20 % RDF (On N eq basis through button mushroom waste), T3: 80 % RDF + 20 % RDF (On N eq basis through button mushroom waste) + PSB + RZB, T4: 60 % RDF + 40 % RDF (On N eq basis through button mushroom waste), T5: 60 % RDF + 40 % RDF (On N eq basis through button mushroom waste) + PSB + RZB, T6: 80 % RDF + 20 % RDF (On N eq basis through shitake mushroom waste), T7: 80 % RDF + 20 % RDF (On N eq basis through shitake mushroom waste) + PSB + RZB, T8: 60 % RDF + 40 % RDF (On N eq basis through shitake mushroom waste), T9: 60 % RDF + 40 % RDF (On N eq basis through shitake mushroom waste) + PSB + RZB, T10: 80 % RDF + 20 % RDF (On N eq basis through oyster mushroom waste), T11: 80 % RDF + 20 % RDF (On N eq basis through oyster mushroom waste) + PSB + RZB, T12: 60 % RDF + 40 % RDF (On N eq basis through oyster mushroom waste, T13: 60 % RDF + 40 % RDF (On N eq basis through oyster mushroom waste) + PSB + RZB. Bio-inoculated/un-inoculated pea seeds as per treatment combination were sown at a spacing of 60 × 7.5 cm. Different spent mushroom substrate and biofertilizers amended treatment combinations significantly influenced yield (green pod & seed) and plant growth attributes of pea crop. The treatment combination which comprised of 80 % RDF + 20 % RDF on N eq. basis through button mushroom substrate (T3) resulted in plants which had maximum plant height (110.80 cm), number of branches (4.77), pod length (6.61 cm), pod diameter (1.23 cm), pod weight (6.56 g), number of grains per pod (8.32), number of pods per plant (28.37), green pod yield per plant (135.24 g), yield per hectare (176.95 q) with shelling of 43.54 per cent. This treatment combination also resulted in higher seed yield and good quality parameters viz. seed yield per hectare (18.91q), 100 seed weight (16.47 g), germination (94.63 %), seed vigour index-I (1821.90), and seed vigour index-II (3819.50) and minimum severity of leaf blight (9.10 %). After harvesting of the crop soil analysis also revealed that maximum availability of N: P: K (413.95: 55.20: 413.98 kg/ha) were in treatment T3 (80 % RDF + 20 % RDF on N eq. basis through button mushroom waste + PSB + RZB) with an increase of 30.73, 62.07 and 29.99 per cent, respectively over the recommended practice (316.64: 34.06: 318.46 kg/ha). The annual net return over the two years of study was found significantly highest (Rs 220868.33 per hectare) with a B: C ratio of 3.52 in the same treatment. The experimental findings have proved the utility of SMS as an important source of nutrients in cultivation of pea. On the basis of two years study, it can be concluded that treatment combination T3 (80 % RDF + 20 % RDF on N eq. basis through spent button mushroom substrate + PSB + RZB) resulted in saving of 20 % fertilizers (NPK), better growth, improved yield and net returns.

    HETEROSIS AND COMBINING ABILITY STUDIES USING CYTOPLASMIC MALE STERILITY IN CAULIFLOWER (Brassica oleracea L. var. botrytis L.)
    (UHF,NAUNI, 2021-03) NAIR SUNIL APPUKUTAN, NAIR SUNIL; MEHTA, DEVINDER KUMAR
    ABSTRACT The present investigation entitled “and Combining Ability Studies Using Cytoplasmic Male Sterility in Cauliflower (Brassica oleracea L. var. botrytis L.)”was conducted during the years 2018-2020 at research farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) to assess the information on gene action as inferred from the combining ability analysis and magnitude of heterosis for different yield related traits. Thirty cross combinations generated from crossing of three CMS lines (UHF-CAU-CMS-1, UHF-CAU-CMS-2, UHF-CAU-CMS-3) with 10 testers (PSBK-1, PSBKT-25, Early Snowball, Cambridge No. 5, Olympus, Snowball Super, White Heart, Champion, Early London, White Rock) in Line × Tester mating design were evaluated along with parents and a check (Pusa Snowball Hybrid-1) in randomized complete block design (RCBD) with three replication. The genotypes and crosses were evaluated for various quantitative traits viz., plant height, days to 50 per cent curd harvesting, number of leaves per plant, leaf length, leaf breadth, plant spread, stalk length, curd equatorial length, curd polar length, curd size index, curd solidity, gross plant weight, marketable curd weight, marketable curd yield, net curd weight, , harvest index and disease parameters such as Sclerotinia rot incidence and black rot severity. The quality traits such as leaf attitude, leaf shape, leaf colour, leaf waxiness, curd covering by inner leaves, curd knobbing, curd texture, curd shape, curd doming, curd colour, curd riceyness and curd anthocyanin at the time of maturity were also recorded on basis of DUS characterization. Analysis of variance for the data revealed significant differences among the genotypes for most of the traits investigated. The combining ability analysis revealed significant differences due to lines, testers and line x tester interactions for most of the traits when tested against error indicating appreciable diversity in the experimental material. The experimental results revealed UHF-CAU-CMS-1 as the best general combiner for various traits such as plant height, leaf length, plant spread, curd polar length, curd size index, gross plant weight, marketable curd weight, while; UHF-CAU-CMS-2 excelled with desirable GCA effects for traits viz., days to 50 per cent curd harvesting, leaf breadth, curd equatorial length, curd solidity and net curd weight. The experimental results inferred that on the basis of GCA analysis and mean performances, the parents, UHF-CAU-CMS-2 (Line) and PSBK-1, Early London and Snowball Super (testers) were found superior for majority of yield contributing traits. The cross combinations UHF-CAU-CMS-1 × Snowball Super, UHF-CAU-CMS-1 × PSBK-1 and UHF-CAU-CMS-2 × Early London were the three best performing crosses on the basis of their per se mean performance, SCA analysis and heterotic effects for majority of yield traits such as curd size index, marketable curd weight/curd yield, net curd weight and its contributing traits. These crosses also exhibited less Sclerotinia rot incidence and black rot severity and had desirable curd traits such as snow-white curds, curd covering by inner leaves, compact curds and were free from curd riceyness. The estimates of variance ratio (σ2A/ σ2D) were less than unity for most of the traits substantiating the role of non-additive gene action for the traits suggesting the exploitation of heterosis breeding for further improvement in the mid-late and late maturity groups of cauliflower. Hence, these three cross combinations should be further evaluated at multi-locations before releasing as a substitute of already existing hybrids of cauliflower.
