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 IN VITROCELL SELECTION IN TOMATO (Solanum lycopersicumL.) AGAINST BUCKEYE ROT [Phytophthora nicotianae var.parasitica(DASTUR) WATERHOUSE
    (2015) ABHISHEK, KUMAR; KAUR, RAJINDER
    ABSTRACT The present investigation aimed at in vitrocell selection in tomato (Solanum lycopersicumL.) against buckeye rot (Phytophthora nicotianae var. parasitica (Dastur) Waterhouse). Leaf, internode and root explants from in vitro geminated seedlings of cv. Solan Vajr were used for callus induction. The seeds were surface sterilized by treating them with 0.1% (w/v) of bavistin and 0.5% (v/v) sodium hypochlorite for different time intervals. Treatment of leaf explant with 0.1% (w/v) of bavistin for ten minutes and 0.5% of (v/v) sodium hypochlorite for three minutes was the most effective giving 68.05% uncontaminated cultures and 60.94% survival of seedlings. the MS medium supplemented with 1.2 mg/l GA3gave the best seedling germination of 32.33%. MS medium supplemented with 3.0 mg/l NAA+ 1.0 mg/l BAP gave best growth of callus. Leaf and root explants gave 95.21 % and 81.11 % callus induction, respectively, but internode gave maximum callus induction of 100.00%. The calli were subjected to different concentrations of culture filtrate of Phytophthora nicotianae var. parasitica and calli survival at 20% as selective dose of culture filtrate was 30.64%. The selected calli did not respond very well for the regeneration. The callus turned to slightly raised green nodulation on different combination of growth regulators but no shoots were formed. Molecular studies revealed that theselected tolerant calli were different at genomic level from the normal callus and the differences do not only exist at morphological level but they are also present at DNA level. Thus it was concluded that in cv. Solan Vajr callus can be used for cell selection studies and Culture filtrate of pathogen was injurious to the survival of callus beyond 20%.
