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 VARIABILITY IN APPLE (Malus × domestica Borkh.)
    (UHF,NAUNI, 2019-12) KUMAR, LOKENDER; DOGRA, R K
    ABSTRACT The present investigation entitled “Studies on genetic in apple (Malus × domestica Borkh.)” was carried out at Regional Horticultural Research and Training Station Bajaura, Seobagh (HP) during 2018-2019 with the objective of studying the variability in different apple cultivars and to assess the association among yield and other traits for quantification of promising cultivars for future use. Twelve cultivars of apple namely, Red Chief, Vance Delicious, Oregon Spur II, Super Chief, Scarlet Gala, Gale Gala, Red Delicious, Top Red, Scarlet Spur Red Delicious, Early Red One, Red Fuji and Gold Spur were evaluated for their plant growth, floral, fruiting and chemical characteristics. Analysis of variance showed significant differences among all the genotypes for all the characteristics under study viz., tree height, tree spread, trunk girth, annual shoot growth, tree volume, leaf area, bud burst, first flower open, full bloom, petal fall, duration of flowering, fruit shape, bearing habit, fruit colour, fruit set, fruit drop, fruit length, fruit breadth, fruit weight, fruit volume, yield per tree, yield efficiency, total soluble solids, fruit firmness, titratable acidity, sugaracid ratio, total sugars, reducing sugars and non-reducing sugars. The genotypes Scarlet Spur Red Delicious followed by Red Chief, Super Chief were found promising for fruit length, fruit breadth, fruit weight, fruit volume, titratable acidity and non-reducing sugars whereas Red Delicious V-22 was found promising for yield per plant (kg). A high phenotypic and genotypic coefficient of variation was recorded for tree volume. High heritability coupled with high genetic gain was obtained for trunk girth, tree spread, tree volume, titratable acidity, non-reducing sugars sugaracid ratio, fruit volume, fruit set and fruit drop. High heritability coupled with moderate genetic gain was obtained for leaf area, total soluble solids, total sugars, reducing sugars, fruit weight and fruit firmness, thereby indicating selection of these traits for crop improvement. A highly positive and significant correlation coefficient of yield per plant was observed with annual shoot growth followed by tree height, trunk girth, tree spread, tree volume and leaf area at both phenotypic and genotypic levels. Maximum positive direct effect cited towards yield were contributed by tree height followed by average leaf area, trunk girth, fruit firmness, yield efficiency, fruit breadth, tree spread, fruit weight, fruit volume and duration of flowering
