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.

    ASSOCIATION GENETICS IN POPULUS DELTOIDES
    (UHF,NAUNI, 2017-12) THAKUR, SHIKHA; THAKUR, SANJEEV
    ABSTRACT The present investigation entitled “Association genetics in Populus deltoides” was carried out in the Department of Tree Improvement and Genetic Resources, Dr Y. S. Parmar University of Horticulture & Forestry Nauni, Solan (HP) during 2013-2016. There is a collection of Populus deltoides clones procured from different countries namely USA, Australia and parts of India and maintained in the germplasm block of Naganji nursery from which ninety five clones were included in the study. Cuttings were raised in the nursery in RBD with three replications at 50 cm X 50 cm spacing and were evaluated for morphological characters in field as well as wood and molecular studies in laboratory. Analysis of variance revealed that all morphological traits were significantly different in nature. On the basis of clustering of morphological and wood traits, ninety five clones were distributed into five distinct clusters suggesting the presence of different sources of relationships amongst the clones. The gene action study revealed that additive variance was observed more than the dominance variance for most of the parameters studied except for growth traits. Growth traits expressed highly significant and positive genotypic as well as phenotypic correlation. Ninety five clones were tested for their genetic diversity using hundred SSR markers out of which ninety three gave results and sixteen ISSR markers out of which ten markers gave results. Results disclosed that dendrogram generated from ninety three SSR markers divided whole population of ninety five clones into two major clusters whereas dendrogram generated from ISSR markers depicted that whole population was divided into three major clusters. The structure analysis from SSR data revealed that the population gets divided into two sub-populations whereas from ISSR data, it was clear that the population gets divided into three sub-populations indicating the level of diversity existing in the population. On the basis of population structure analysis it is concluded that this clonal population structure is diverse. Results from genetic diversity analysis as well as STRUCUTRE analysis showed that the clustering pattern of the genotypes in STRUCUTRE analysis were almost similar to the splitting in the UPGMA tree which reveals that all the genotypes were clustered better with two clusters in SSR markers and three clusters in case of ISSR markers. Association studies of commercially important wood traits were conducted using ISSR and SSR marker data. Some important associations of markers with specific gravity of poplar wood were found in case of SSR markers whereas with ISSR markers, various associations of holocellulose and lignin content were obtained.
