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.

    HALF-SIB PROGENY EVALUATION AND GENETIC DIVERGENCE STUDIES INGrewia optiva DRUMMOND
    (UHF,NAUNI, 2019-06) BHAGTA, SHIKHA; SANKHYAN, H P
    ABSTRACT The present investigation entitled ā€œ Half sib progeny evaluation and genetic divergence study in ā€œ was conducted at the experimental field of the Department of Tree Improvement and Genetic Resources, College of Forestry, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during the years 2015 - 2019. Three experiments were conducted i.e (I) to assess the performance of Half-Sib Progenies of Grewia optiva Drummond at the age of 16 years for qualitative and quantitative characteristics, (II) to study genetic divergence in the study material through quantitative and molecular markers, (III) to study different families for amenability to vegetative propagation through cuttings. In first experiment, out of 60 families, only 40 families were selected. These families include BI-1, BI-3, BI-4, CH-1, CH-3, CH-4, CH-6, HA-2, HA-3, HA-4, HA-5, KA-1, KA-2, KA-3, MA-2, MA-3, SH-2, SH-3, SH7, SI-3, SI-4, SI-5, SI-6, SI-7, SI-10, SI-11, SI-13, SI-14, SI-15, SI-16, SO-1, SO-2, SO-3, SO-4, SO-5, SO-7, SO-8, SO-9, SO-10, SO-11 and SO-12. Morphometric and fodder quality parameters were evaluated for these 40 families only with three genotypes of each family spaced at 2x2 m. The maximum mean performance values was recorded for different morphometric parameters, viz., height (9.20 m), diameter (16.19 cm), leaf area (77.22 cm2), estimated numbers of leaves (3634.3), fresh weight of 100 leaves (87.00 g), dry weight of 100 leaves (50.33 g), leaf dry matter content (55.56 %), total fresh leaf biomass (3024.94 g) and fodder yield (13.81 kg) among 40 families. Leaf samples from all the 40 families selected were collected in month November for proximate fodder analysis, which varied significantly among the different families in the seedling seed orchard. The maximum mean crude protein (22.11%), crude fibre (21.84%), ash content (13.13%), ether extract (5.88%), and nitrogen free extract (45.61) respectively was recorded among 40 families of Grewia optiva. After evaluation of these families, top ranking ten families (SI-15, SO-3, HA-2, HA-3, HA-4, SO-7, SH-7, SO-4, SI-6 and SI-14) were taken as best performers on the scoring index basis on desired morphometric and fodder quality characteristics. These best performer families were further studied for genetic divergence through molecular markers and amenability to vegetative propagation through cuttings. In second experiment diversity analysis amongst 10 different families of Grewia optiva was carried out using 15 RAPD and 20 ISSR primers and 9 RAPD and 12 ISSR primers show amplification respectively. Family SH-7 (Taradevi-Shimla) came as outliner as revealed by both RAPD and ISSR study. In third experiment, cuttings were taken from best performer 10 families and treated with different auxins (IBA and NAA) concentration and raised in three different seasons (spring, monsoon and winter). Spring season (S1) during March (First week) was found to be effective among other different seasons for raising cuttings of Grewia optiva as quality planting stock .Family SH-7 was found to be a best source for raising cuttings of Grewia optiva Drummond. IBA 500 mg/lit auxin concentration was found suitable treatment for raising cuttings of Grewia optiva. Morphological and genetic variation can be exploited for the further selection of suitable genotypes in accordance the domestication process of this important and valuable plant bioresource /agroforestry species and to develop further hybridization works and preparing true to type (mother replica) for tree improvement programme.
