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 MORPHO-CHEMICAL VARIATION IN GYNODIOECIOUS Valeriana jatamansi JONES
    (UHF,NAUNI, 2017-12) THAKUR, PANCY; SHARMA, YASH PAL
    ABSTRACT The present investigation entitled “Studies on morpho-chemical variation in gynodioecious Valeriana jatamansi Jones” was carried out in the field and laboratory of the Department of Forest Products, College of Forestry, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2014-16. The study was conducted under five broad heads namely (i) Morphological features and isolation of morphovariants, (ii) Stability of morphological features of morpho-variants, (iii) Evaluation of different morphovariants for phytochemical content and yield, (iv) Progeny evaluation of female & and bisexual plants, and (v) Standardization of analytical method for quantification of valepotriates. Already existing plants of different germplasms i.e. IVth inbred generation of INGR 11036 (IC 05844665), IVth inbred generation of “A” germplasm and general plants of different populations of Valeriana jatamansi were utilized for the present study. Wide variation in the plants for plant habit, leaf characteristics and floral parameters was observed. Detailed morphological studies resulted in identification of 46 morpho-variants differing in atleast one distinct qualitative morphological feature. Out of 46 selected morpho-variants, 25 morpho-variants were female flowering plants and 21 morpho-variants were bisexual flowering plants. The distinct qualitative morphological features of morpho-variants were found stable in the vegetatively raised offsprings of all the morpho-variants. Significant variation was recorded among the morpho-variants with regard to leaf length, leaf width, ratio of leaf length and leaf width, plant height, petiole length, petiole diameter, rhizome diameter, fresh & dry aerial biomass, fresh & dry rootstock biomass and flowering initiation. Among female and bisexual morpho-variants, significant difference was observed for plant height, leaf width, petiole diameter and fresh and dry biomass of rhizomes. Phytochemical analysis revealed wide variation in concentration of valepotriate’s (valtrate, acevaltrate, Didrovaltrate & IVHD Valtrate) in roots, rhizomes & rootstocks of different morpho-variants. The valtrate content varied from 0.749% to 2.878% in rhizomes, 0.917% to 5.221% in roots and 0.927% to 3.267% in rootstock; acevaltrate content varied from 0.022% to 0.512% in rhizomes, 0.015% to 1.647% in roots and 0.260% to 0.909% in rootstock; didrovaltrate content varied from 0.187% to 1.688% in rhizomes, 0.053% to 0.365% in roots and 0.136% to 0.958% in rootstock; IVHD valtrate content varied from 0.179% to 1.491% in rhizomes, 0.176% to 0.755% in roots and 0.214% to 1.101% in rootstock of different morpho-variants. The total valepotriate’s content varied between 1.761% to 4.848% in rhizomes, 1.598% to 6.420% in roots and 1.845% to 4.875% in rootstock of different morpho-variants. The concentration of diene type of valepotriate’s was more in roots than rhizomes and monoene type of valepotriate’s were more in rhizomes than roots. On the basis of phytochemical content and morphological studies, promising morpho-variants has been identified which can be further used for breeding purpose for isolation of chemotype/variety with stable and distinct morphological features. Seasonal variation studies indicated that during September month, valepotriates content was maximum but due to higher rootstock biomass, valepotriate’s yield was maximum in November month. Analytical method for quantification of individual valepotriate’s through HPLC has been standardized and developed.
