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.

    MORPHOGENETIC VARIATION FOR LEAF FODDER QUALITY PARAMETERS IN POPULATIONS OF Grewia optiva DRUMMOND
    (2023-08-25) JYOTI DHIMAN; HARI PAL SANKHYAN
    ABSTRACT The present investigation, entitled "Morphogenetic variation for leaf fodder quality parameters in populations of Grewia optiva Drummond" was conducted during 2020–2023 in the Department of Tree Improvement and Genetic Resources, College of Forestry, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). This investigation was conducted in the four altitudinal ranges (400 to 800 m (A1), 801–1200 m (A2), 1201–1600 m (A3), and 1601-2000 m (A4) above mean sea level (a msl)) of Himachal Pradesh and Uttarakhand. Four major experiments were conducted viz., morphological and genetic diversity of Grewia optiva Drummond, physiochemical properties of soil, variation in fodder quality characteristics and molecular markerbased analysis of the best studied material of this species. All physiochemical soil properties declined as soil depth increased from 0 to 15 cm to 15 to 30 cm, with the exception of bulk density and particle density. The proportions of soil organic carbon, soil nitrogen and soil porosity increased from A1 to A4 altitudinal zone. Based on useful and desired characteristics of both morphometric and fodder quality parameters six populations, i.e., Harsar, Sujanpur Tihra, Sihunta, Kutuldi, Jagdhar and Sangrah and altitudinal zone A4 (1600-2000m) reported as best for further selection and tree breeding program. These populations reported with more than 23 per cent crude protein. Variability estimates, genetic parameters, correlation and divergence studies exhibited high variability between and among populations. 15 genotypes DH1 (Dharot 1), DH2 (Dharot 2), DH4 (Dharot 4), HR1 (Harasar 1), ST1 (Sujanpur Tihra 1), DR1 (Dramman 1), DR2 (Dramman 2), NR4 (Neri 4), DA3 (Daggar 4), BA3 (Basal 3), KU1 (Kutuldi), SI2 (Sihunta 2), SI3 (Sihunta 3), KT1 (Kuthar 1) and KT2 (Kuthar 2)) were identified based on seedling growth and fodder quality characteristics at 18 months old seedlings. Only two of the 10 ISSR primers, i.e., UBC 809 and UBC 820 were amplified and generated a banded pattern. Maximum variation was observed in the progeny of the DA3 (Daggar) and DH2 (Dharot) genotypes. Morphological and genetic variation can be used to select suitable genotypes in accordance with the domestication process of this important multipurpose species, to develop further hybridization work and for mass multiplication of selected superior nutritive selections
