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.

    STUDIES ON PROVENANCE VARIATION IN Toona ciliata M. ROEM
    (UHF,NAUNI, 2021-02) NARENDRA, SINGH; GUPTA, TARA
    ABSTRACT The present research entitled “Studies on provenance variation in M. Toona ciliataRoem” was carried out in the Department of Tree Improvement and Genetic Resources, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Field survey was carried out across the population of Toona ciliata through HP,UK and UP to select well represented twelve provenances viz., P1 (Nauni), P2 (Hamirpur), P3 (Thakurduara), P4 (Ghumarwin), P5 (Nurpur), P6 (Nainikhad), P7 (Una), P8 (Rajpur), P9 (Kathgodam), P10 (Naini), P11 (Nagina) and P12 (Sarsawa). The trees of approximately same age group were randomly selected and phenotypic characters viz., tree height, tree diameter, crown spread, clear bole height and crown area were recorded. The seeds were collected from individual trees for seed studies. The data analyzed by RBD and CRD revealed that there was significant variation in provenances and maximum seed germination percentage from Nauni provenance. In order to study variability status of individual mother trees selected under each provenance, progenies of individual tree were raised in Randomized Block Design to assess the growth performances w.r.t germination energy index (%), seedling survival (%) seedling height (cm), collar diameter (mm), number of leaves and branches and leaf length. Half sib progenies performances revealed significant variation within provenances suggesting for single tree selection. The genetic estimates suggested intensive selection as high heritability followed by high genetic gains were obtained for crown spread and tree height. Similarly high correlation for collar diameter with mother tree height and 100 seeds weight was observed. The study revealed significant variation in chemical characteristics of wood from different provenances of Toona ciliata. The wood chemical analysis revealed that highest sapwood moisture content (58.98 %) was observed from Nauni, whereas minimum (29.05 %) was recorded from Ghumarwin. The heartwood moisture content was observed highest (54.94 %) from Hamirpur. The study revealed that heartwood moisture content was positively correlated with sap wood moisture content. The maximum holocellulose (74.50%) and lignin (28.50%) contents were recorded from Naini and Nauni respectively while, minimum holocellulose (65.10%) and lignin (16.83 %) was noticed from Nauni and Hamirpur. The study revealed that heart wood moisture content was positively correlated with sap wood moisture content (0.926). It was also observed that heart wood moisture content was positively correlated with heartwood maximum moisture content (0.587), sapwood maximum moisture content (0.636), cold water soluble extractive (0.697), hot water soluble extractive (0.772), alcohol benzene soluble extractive (0.616) and lignin content (0.665). The moderate to high heritability and genetic gains were estimated for collar diameter and seedling height till one year age suggesting early selection
