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.

    Genetic Analysis for Growth and Oleoresin Traits of Chir pine (Pinus roxburghii Sargent)
    (YSPU, 2015) Bhat, Sheeraz Saleem; Singh, N.B.
    The present investigations entitled “Genetic Analysis for Growth and Oleoresin Traits of Chir pine (Pinus roxburghii Sargent)” were carried out in the Research field and Laboratory of the Department of Tree Improvement and Genetic Resources, College of Forestry, Dr YSP University of Horticulture and Forestry, Nauni, Solan (HP) during the year 2010-2012, to: 1) 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 progenies; 2) to carry out molecular characterization through RAPD, ISSR and SSR markers, and, 3) to carry out marker trait association for the aforesaid traits, besides the oleoresin yield of the different genotypes. All the traits varied significantly, with mean values height (18.08 m), diameter at breast height (34.76 cm), bark thickness (2.73 cm), crown height (7.80 m), crown length (10.38 m), needle length (20.78 cm), thickness (0.61 mm), number of stomata per mm of a row (9.71), wood moisture content (54.31%), specific gravity (0.41) and tracheid length (1.68 mm). Variability estimates, genetic parameters, correlation studies, principal component analysis and divergence studies exhibited high variability among all the half sib progenies. Characters which exhibited high heritability like crown height (H2=0.45), wood specific gravity (H2=0.66), needle thickness (H2=0.48), followed by higher genetic gain show additive genetic variation and can be exploited quiet well in advanced breeding programs, thus more effective in selecting the best genotypes for a trait. Genetic divergence was studied through cluster analysis and dendrograms. Molecular characterization through RAPD, ISSR and SSR revealed high polymorphism percentage (90.14, 94.84 and 100, respectively); with respective band size ranges 105-1490 bp, 198-2015 bp and 103-239 bp. Dendrogram based on these markers, individually as well as combined, were made for diversity analysis. Structural analysis was carried out for the population diversity studies, and for association mapping. Three clusters resulted for each marker, beside some genotypes as admixtures. Association mapping with different traits revealed 12 associations with RAPD markers, 6 associations with ISSR markers, 8 associations with SSR markers at P value (<0.05). Coefficient of determination, R2 value, ranged from 0.0757 for UBC841 with wood specific gravity to 0.1495 for NAD3-1 with crown length.
