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.

    SELECTION AND CHARACTERIZATION OF SUPERIOR GENOTYPES FROM SEEDLING TREE POPULATION OF WALNUT (Juglans regia L.) IN CHAMBA DISTRICT OF HIMACHAL PRADESH
    (UHF,NAUNI, 2022-10) AHIR, MEGHA; CHAUHAN, JITENDER K
    ABSTRACT The present study “Selection and characterization of superior genotypes from seedling tree population of walnut (Juglans regia L.) in Chamba district of Himachal Pradesh” aimed to assess the nature and magnitude of variability in walnut of existing plantations. On the basis of pre selection survey, a total of 98 healthy and bearing walnut genotypes were marked across walnut growing areas of Chamba district of Himachal Pradesh during 2019-2021. Marked trees were observed to be erect to semi-erect to spreading in growth habit, trunk girth, yield and yield efficiency varied between 53.15-422.55 cm, 3.44 to 57.93 kg/tree and 0.79-80.06 g/cm2, respectively. Low variation witnessed in various leaf characters. None of the marked trees was noticed to be lateral bearer. The physical nut and kernel characters like nut length, nut width, nut weight, shell thickness, shelling percenatage, thickness of dividing membranes, kernel weight, kernel length, kernel width and kernel percentage ranged from 29.30-48.64 mm, 27.91-39.66 mm, 9.73-23.34 g, 0.83-2.59 mm, 48.49-81.71 per cent, 0.13-3.18 mm, 2.82-9.26 g, 24.79-37.52 mm, 22.18-32.29 mm, 18.29-51.51 per cent, respectively among different walnut genotypes. High heritability with high value of genetic gain was obtained for yield efficiency and yield; with moderate genetic gain in kernel weight, shell thickness and nut weight in the genotypes under study which indicated that these characters were under the strong influence of additive gene action and hence simple selection procedure based on phenotypic expression of these traits would be more reliable. Maximum positive direct effect cited towards yield was contributed by kernel weight, nut width, nut length, leaf: leaflet width, shelling percentage, leaf: leaflet length, kernel percentage and thickness of dividing membranes. According to PCA, 6 principal components accounting for 83.46 per cent of total variance was extracted. Variables with high discriminating values including kernel weight, kernel percentage, kernel length, kernel width, nut length, nut width and nut weight were identified as the most useful variables for evaluation. On the basis of these variables, 9 superior genotypes were selected. On the whole, the present study has resulted in some elite walnut selections of indigenous origin representing a valuable genepool for use in future.
