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.
