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 MORPHOLOGICAL, ESSENTIAL OIL AND MOLECULAR DIVERSITY IN Tagetes minuta L. IN HIMACHAL PRADESH
    (UHF,NAUNI, 2017) BANDANA, KUMARI; RAINA, RAVINDER
    ABSTRACT The present investigation entitled “Studies on morphological, essential oil and molecular diversity in Tagetes minuta L. in Himachal Pradesh” was carried out both in field as well as in laboratory of the Department of Forest Products, College of Forestry, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2014-17. These studies were divided into six experiments namely (i) Morphological studies (qualitative as well as quantitative) (ii) Interpopulation growth and development studies (iii) Breeding & Genetic System studies,(iv) Growth and Development studies, (v) Seed studies and (vi) Genetic variability studies through DNA based molecular markers. The seed was sourced from 32 different agroclimatic regions of Himachal Pradesh. All the accessions were deposited with NBPGR, New Delhi and IC numbers (IC 617291-617300 and IC 614570-614591) obtained. All the accessions were found to be same for qualitative morphological parameters. Significant variation was obtained for many quantitative characters. Maximum plant height of 191.78 cm in accession 8, maximum collar diameter of 15.26 mm in accession 21, the number of main branches per plant maximum in accession 27(7.42), leaf length highest in accession 31(19.79 cm),maximum number of leaflets in accession 12(12.55) was observed on the basis of pooled data of two years. Maximum gland density in accession 28 (1.34 mm-2), number of ray and disc florets highest in accession 7(2.81 and 4.50), size of disc floret ovary maximum in accession 21(5.21mm), disc floret ligule size maximum in accession 25 (4.07mm), ray floret ovary size maximum in accession 11 and size of ray floret ligule maximum in accession 25(3.97mm) was observed. As both the leaf and flower oil cannot be harvested at the same stage due to different growth stages, the biomass and oil yield parameters were taken at both preflowering (leaves being in full flush) and full flowering stage. Significant variation was observed for biomass and oil yield parameters among the studied accessions. On the basis of maximum biomass and yield parameters, five accessions were identified: i) Accession 6(highest in flower oil yield), ii)Accession 9(highest in leaf biomass and leaf oil yield), iii)Accession 10(highest in flower biomass yield) iv)Accession 30(highest in leaf and flower oil content) v) Accession 32(highest in leaf oil yield). These accessions were subjected to chemical characterization through GC-MS analysis and considerable variation was observed between and within leaves and flowers oils. Clustering based on morphological and yield parameters showed interesting results of grouping accession 6&9 in same cluster and accession 10, 30 & 32 in other same cluster. Highest heritability was observed for number of leaflets per leaf (96.49%) followed by leaf length (90.68%). Considerable variation in the biomass and oil content was observed between different months suggesting July being the best month for leaf oil harvesting and September for flower oil harvesting. Breeding system studies indicated the self pollinating nature of Tagetes minuta in addition to cross pollinating feature of the plant. The genetic system studies confirmed the earlier reports of 2n = 48 chromosomes. Seed studies showed significant variation for all the germination parameters with accession 9 standing the highest for germination percentage (93.33%), germination energy index (81.11%), speed of germination (16.59%) and peak value (11.42%). On the basis of ISSR marker analysis, the studied accessions broadly clustered into two main groups with one group consisting of accessions 6, 7, 8 and 9 and other group consisting of remaining 28. Three accession 1, 23 and 26 are genetically identical. ISSR-(GA) 8WC with PIC value of 0.72 is more suitable for genetic analysis in this species.
