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 GENETIC IMPROVEMENT OF Punica granatum L. (WILD POMEGRANATE)
    (UHF,NAUNI, 2022-07) Divya; Gupta, Tara
    ABSTRACT The present investigation entitled “Studies on Genetic Improvement of Punica granatum L. (wild pomegranate)” was carried out in the Department of Tree Improvement and Genetic Resources, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during 2019-2022. Four site viz., Narag (S1), Waknaghat (S2), Jonaji (S3) and Nauni (S4), each with three genotypes, were selected for reproductive studies and the data obtained was analysed using suitable methods i.e. CRD for laboratory experiments and RBD for field experiments. Hybridization was carried out using three lines at Narag site and nine tester from threes sites viz., Waknaghat (S2), Jonaji (S3) and Nauni (S4), each site with three testers, followed by testing of paternity through ISSR markers. Results revealed that the genotypes of the site Waknaghat and Jonaji showed early flowering as compared to genotypes of the site Narag and Nauni. Leaf size (leaf length=4.59 cm; leaf width=2.25 cm and leaf area= 5.89 cm2) and flower size (petal length=20.16 mm and number of stamens=360.84) at Narag were better than the other selected sites. Pollen viability was maximum (84.02 %) for the genotypes at Nauni site, however germination of fresh pollen (72.40 %) and stored pollen (36.52 %) was highest for the Narag site. Results of the hybridization study revealed that cross S1G3×S2G3 performed best for the physical fruit characters viz., fruit length (5.82 cm), fresh fruit weight (84. 65 gm), fresh rind weight (43.40 gm), fresh aril weight (41.25 gm) and number of arils per fruit (303.25), and for total soluble solids (16.59 °B). cross S1G2×S2G2 performed best for nursery growth characters at later stages viz., twelve months (plant height=70.90 cm; collar diameter=5.16 mm and number of leaves per plant=211.47) and eighteen months of age (plant height=83.67 cm; collar diameter=7.38 mm; number of leaves per plant=284.07 and leaf width=2.59 cm). Tester S2G1 and S2G2 were better combiner among all the testers for plant height, collar diameter, number of leaves per plant, leaf length, leaf area and petiole length. Additive variance was higher than the dominance variance and contribution of testers was higher than the line and Line × Tester interaction for all nursery characters except for the number of branched per plant at eighteen months of age. Number of leaves per plant showed maximum heritability, however maximum genetic gain was estimated for the leaf area, due to the greater phenotypic variation in the leaf area as compared to the number of leaves per plant. S1G1×S2G1, S1G2×S2G2, S1G2×S2G3, S1G3×S2G1, S1G3×S2G2 and S1G3×S3G2 cross showed positive heterosis over better parent for all nursery growth characters. ISSR primers viz., ISSR-UBC-811, ISSR-UBC-823, ISSR-UBC-827, ISSR-UBC-836, ISSR-UBC-840, ISSR-1, ISSR-3 and ISSR-8 were helpful in the confirmation of paternity of the hybrids. The finding of present study can be utilized for pomegranate breeding programme through pollen collection from early flowering genotypes, selection of suitable parents on the basis of their combining abilities and paternity testing by ISSR markers
