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.

    Genetic studies for yield and quality traits in tomato (Solanum lycopersicumL.)
    (YSPU, 2016) Rakesh; Sharma, Hem Raj
    The present investigation entitled “Genetic studies for yield and quality traits in tomato (Solanum lycopersicum L.)” was carried out at the Experimental Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2014-15 and 2015-16 to know the extent of heterosis, assessing combining ability and generating information on gene action. Six diverse tomato genotypes were crossed in a diallelb fashion (excluding reciprocals) during Kharif2014-15 and in the next year fifteen crosses alongwith 6 parents and one standard check (Naveen 2000+) were evaluated in RCBD. Analysis of variance showed significant differences among all the genotypes for all the characters under study. The genotypes, EC-1055 and EC-1057 among parents while Solan Lalima x EC-1057 and Solan Lalima x EC-1058 among cross combinations were found superior for earliness. Heterobeltiosis for fruit yield and quality traits was recorded significantlypositive in Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058. Maximum negative heterosis for buck eye rot incidence and alternaria blight severity was observed in Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058. For yield and component traits Solan Lalima was good general combiner. Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were good specific combiners for fruit clusters per plant, number of fruits per cluster, number of fruits per plant, harvest duration and fruit yield traits. Solan Lalima and UHF-55 were good general combiners for total soluble solids, lycopene content and ascorbic acid content. Cross combinations viz.Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were good specific combiners for all quality traits. Solan Lalima was good general combiner for buck eye rot incidence, alternaria leaf blight severity, septoria leaf blight severity and fruit borer infestation. The estimates of σ 2 g/σ 2 s (predictability ratio) were found to be < 1 for almost all the traits included in this study except for plant height, fruit size, buck eye rot incidence and fruit borer infestation indicated predominance of non additive gene action.
