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.

    EVALUATION OF HIGH RESIN YIELDING HALF SIB FAMILIES OF Pinus roxburghii Sargent
    (UHF,NAUNI, 2021-10) RAJENDER KUMAR; SANKHYAN, H P
    ABSTRACT The present investigation entitled, "Evaluation of high resin yielding half sib families of Pinus roxburghii Sargent", was carried out at Shilli Conservation Reserve, Solan during the year 2020-2021 to evaluate different growth traits (height, diameter at breast height, bark thickness, crown height and crown length), needle characteristics (colour, length, thickness and number of stomata per mm of row), wood traits (moisture content, specific gravity and tracheid length) of different half sib Chir pine families as well as to evaluate the oleo-resin yield traits of different half sib Chir pine families. The study revealed that all the traits varied significantly, with mean values diameter at breast height (31.10 cm), height (17.79 m), bark thickness (2.81 cm), crown length (10.75 m), crown height (6.95 m), needle length (25.57 cm), needle thickness (0.70 mm), number of stomata per mm of a row (9.53), wood moisture content (80.95%), specific gravity (0.42) and tracheid length (1.66 mm).Variability estimates, genetic parameters, correlation studies, principal component analysis and divergence studies exhibited high variability among all the half sib families. Characters which exhibited high heritability like bark thickness (H2 = 0.80), tracheid length (H2 = 0.92), no. of stomata (H2 = 0.91), followed by higher genetic gain. Genetic divergence was studied through cluster analysis. The average oleoresin yield was found to be 430.97 g. The turpentine content of oleoresin ranged from 19.45 per cent to 25.4 per cent and highest rosin content 78.60 per cent while the lowest 72.68 per cent. Resin yield was significant with DBH (0.465) and needle length (0.315) and highly significant with bark thickness (0.721). Higher oleoresin yields have been recorded in family which have maximum diameter. It may be concluded that evaluation of the Chir pine diversity can be very useful in qualitative and quantitative improvement of different traits studied. The seed of these high resin yielding families can be used in establishment of seed orchard to increase its number of populations so as to increase the overall resin production.
