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.

    HETEROSIS AND COMBINING ABILITY STUDIES IN CHERRY TOMATO
    (UHF,NAUNI, 2023-02) ARALIKATTI, OMKAR; RAMESH KUMAR
    ABSTRACT The present study entitled “Heterosis and combining ability studies in cherry tomato” was carried out during the Kharif, 2020 and 2021 at the Experimental Farm, Department of Vegetable Science, College of Horticulture, Dr YSPUH&F, Nauni-173 230, Solan (HP), India to elucidate the information on the extent of parameters of variability, mean performance, heterosis, combining ability and nature and magnitude of gene action for various horticultural traits. The experimental material consisted of fifteen diverse parents (twelve lines and three testers) and thirty six F1 hybrids developed from line × tester design and a standard check. The genotypes were evaluated in Randomized Complete Block Design with three replications during Kharif, 2021. The analysis of variance indicated highly significant differences for all the traits studied. High coefficients of variation were found in number of number of fruits per 500g, number of fruits per cluster, number of fruit clusters per plant and average fruit weight. High heritability along with high estimates of genetic gain was observed for number of fruits per 500g, number of fruit clusters per plant, average fruit weight, fruit yield per plant, plant height and number of fruits per cluster. The Line × Tester studies concluded that parents UHF-CT-L-5, UHF-CT-L-7, UHF-CT-L-8, UHF-CT-L-11, UHF-CT-L-12, Punjab Red Cherry and Punjab Kesar Cherry and cross combinations UHF-CT-L-6 × Punjab Red Cherry, UHFCT- L-5 × Punjab Kesar Cherry, UHF-CT-L-3 × Punjab Red Cherry, UHF-CT-L-6 × Punjab Kesar Cherry, UHF-CT-L-11 × Punjab Red Cherry and UHF-CT-L-4 × Punjab Kesar Cherry on the basis of mean performance, general combining ability, specific combining ability and heterosis studies excelled well for all the traits studied. Gene action studies indicated predominance for non additive gene action for all the traits. Hence, these parents and cross combinations can be released as a substitute of already existing varieties/hybrids of cherry tomato after multi-locations testing.

    STUDIES ON GENETIC VARIABILITY IN TOMATO (Solanum lycopersicum L.)
    (UHF,NAUNI, 2017) ARALIKATTI, OMKAR; KANWAR, H.S.
    ABSTRACT The present investigation entitled “Studies on genetic variability in tomato (Solanum lycopersicum L.)” was carried out at Vegetable Research Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during kharif season, 2016. The experiment was laid out in RCBD with three replications comprising of twenty five diverse genotypes of tomato including Solan Lalima as check variety. The observations were recorded on various characters viz., number of primary branches, plant height (cm), number of fruits per cluster, number of fruits per plant, number of fruit clusters per plant, average fruit weight (g), fruit yield per plant (kg), fruit yield per hectare (q), fruit shape index, pericarp thickness (mm), number of locules per fruit, total soluble solids (°B), harvest duration (days) and buckeye rot incidence (%).A wide and significant range of variability was observed for all the characters under study in all the genotypes. In the present investigation, it is concluded that the genotypes namely, UHSB-34, UHSB-28, UHSB-22, UHSB- 8 gave higher yield compared to rest of the genotypes, but the check variety Solan Lalima performed better over all the genotypes with respect to yield. High coefficients of variation were found in number of fruits per plant, number of locules, number of seeds per fruit, fruit yield per plant and fruit yield per hectare. High heritability along with high estimates of genetic gain was recorded for number of fruits per cluster, number of seeds per fruit, average fruit weight, fruit yield per plant and fruit yield per hectare. The path coefficient analysis depicted that number of fruits per cluster had the maximum positive direct effect on fruit yield per plant. The genetic divergence study depicted that the maximum inter cluster difference is in between the Cluster II and V.
