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.

    IN VITRO MUTATIONS, SELECTION AND MOLECULAR MARKERS BASED CHARACTERISATION OF Gerbera jamesonii Hook.
    (2012) GHANI, MINERVA; SHARMA, S.K.
    ABSTRACT In the present studies, entitled ‘In vitro mutations, selection and molecular markers based characterisation of Gerbera jamesonii Hook.’, the regeneration protocols from capitulum and petiole explants have been standardised. MS + 5.0 mg/l BA + 0.5 mg/l IAA and MS + 4.0 mg/l BA + 1.0 mg/l TDZ were found to be the best media for regeneration from capitulum and petiole explants, respectively. The best multiplication medium comprised of MS + 1.0 mg/l BA + 0.5 mg/l IAA and MS + 4.0 mg/l IBA was found to be best medium for root induction. Shoots were treated with eight doses on gamma rays (1.5, 2, 2.5, 5, 10, 15, 20, 30 Gy) and five doses of EMS (0.1, 0.2, 0.5, 0.8, 1.0%, v/v) for two durations (10 and 20 min). Following gamma irradiation maximum survival of plants both in vitro and in vivo was recorded with 1.5 Gy dose and with EMS treatment 0.1 %/ 10 min led to the maximum plant survival both in cultures and in the glasshouse. The LD50 value for gamma rays was 6.5 Gy and for EMS (10min) LD50 value was 6.5 % and less than 0.1 % in case of 20 min treatment of EMS. The increase in the content/activity of proteins, phenols and antioxidant enzymes (SOD, APOX, GR, CAT) and PPO was observed in both kinds of mutated plants. However, no significant difference in sugar content was observed. However, decrease in the total chlorophyll content were observed in both types of mutated plants. Morphologically, mutagenesis (physical and chemical) led to reduction in the number of leaves and leaf area of plants. However, a significant increase in the length of flower scape and flower head size was observed with both kinds of mutagens. Three flower colour variants, two with EMS (0.1%/10 min, 0.5 %/ 10 min) and one with gamma rays (5 Gy), were obtained. Also, a significantly early flowering was induced in the plants after mutagenesis. RAPD and SSR markers revealed 100 % and 96 % polymorphism and value of Jaccard’s similariy coefficient ranged from 0.11-0.80 in case of RAPD markers and 0.23-0.81 in case of SSR markers. All the plants were differentiated in to three major groups, after RAPD and SSR analysis, based on their similarity as represented graphically, from the dendrogram
