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.

    REPRODUCTIVE BIOLOGY OF Bauhinia vahlii Wight. & Arn.
    (UHF,NAUNI, 2017-10) NAGAAR, BIBI; GUPTA, TARA
    ABSTRACT The present investigations entitled “Reproductive Biology of Bauhinia vahlii Wight. and Arn.” was carried out in the Department of Tree improvement and Genetic Resources, Dr. Y.S.Parmar University of Horticulture and Forestry Nauni,Solan (HP) during 2016-2017 by studying selected tree climbers of Bauhinia vahlii from two populations namely S1(Jabli) in district Solan and S2 ( Jorhji) in district Sirmour of Himachal Pradesh. The type of inflorescence is terminal corymbose raceme. The flowers are zygomorphic, bisexual, pedicellate with superior ovary. At the flowering stage calyx has three sepals one free and two partially fused which also extend the physical support to the larger petals. Corolla consists of five petals; three being larger and two smaller. Maximum anthesis was recorded as 62.66 per cent and 59.99 percent during 6.00 am to 9.00 am in S1(Jabli) and S2(Jorhji) respectively. Anther dehiscence take place 2 to 3hrs after anthesis. The initiation of stigma receptivity was observed at about 2hrs after anthesis and remain receptive up to 48hour. This species was found to be open pollinated, mostly pollinated by insect vectors. Controlled crosses were made between the trees of two sites and maximum mean pod setting was recorded in S2 (Jorhji).The pollen viability was found to be maximum from the buds, before anthesis. Pollinators were identified to be Apis indica, Apis dorsata and aphids. The individual tree variability was recorded for hundred seed weight. The tree No. S1T1 registered maximummean seed weight(138.85g) for Site1(Jabli) and in case of Site2(Jorhji) maximum mean seed weight (140.54g) was recorded from tree No.S2T4 which was at par with S2T2 and S2T5.The maximum seed germination(82%) was obtained from S1(Jabli), under glasshouse conditions. The Genetic estimates for morphometric and floral traits showed high genetic coefficient of variability and higher heritability for leaf area, pod length, ovary length, and filament length which indicates that the selection for these traits can bring about effective and desirable improvement in the species by using appropriate mating designs.
