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.

ThesisItem Open Access Development and Evaluation of Instant Papaya Fruit Powder(COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-12-20) Shivani; Verma, Anil KumarMethod for utilization of papaya fruit cv. Madhu for preparation of foam mat dried fruit powder was standardized. The conversion of papaya pulp into foam was optimized by whipping the pulp after addition of carboxy-methyl-cellulose (CMC) and glycerol-mono- stearate (GMS) @ 0-3% each and drying the resultant foam in dehydrator (60±5°C) to a constant moisture content. Drying of papaya foam by using 3% GMS was found the most appropriate with respect to desired foaming properties (foam density, foam expansion and foam stability), physico-chemical and sensory characteristics. Dried powder contained 79.30- 89.83°B TSS, 7.00-10.73% moisture content, 2.40-5.56% ash content, 49.67-62.63% reducing sugars, 74.27-87.73% total sugars, 928.76-1341.20 µg/100g total carotenoids, 0.135-0.276% titratable acidity and 5.07-5.57 pH. Storage of fruit powder packed in aluminium and polyethylene pouches exhibited slight increase its moisture content and pH with minimum changes in different chemical characteristics. The value of different attributes after 90 days of storage of powder in polyethylene and aluminium pouches were 88.00, 88.80 °B TSS, 0.120, 0.130 per cent titratable acidity, 5.65, 5.61 pH, 63.51, 63.46 % reducing sugars, 85.76, 86.40 % total sugars and 9.90, 9.40 % moisture content, respectively with no microbial growth in any of the sample. However, product packed in aluminium pouches exhibited better retention of nutrients as compared to polyethylene pouches. Further, ready to-serve beverage prepared by reconstituting 12% papaya-mango powder in 50:50 proportions and raising TSS to 12°B by adding sugar syrup was found most acceptable with sensory hedonic score of 7.30 on 9-point hedonic scale. Thus papaya fruit can be utilized for preparation of self stable powder using foam mat drying technique.ThesisItem Open Access GENETIC EVALUATION OF TOMATO (Solanum lycopersicum L.) GERMPLASM FOR YIELD AND QUALITY TRAITS(COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-11-14) KASHYAP, ACHAL; KUMAR, DHARMENDRAThe present investigation entitled “Genetic evaluation of tomato (Solanum lycopersicum L.) germplasm for yield and quality traits” was conducted at the experimental farm of RHR&TS, Jachh, Kangra, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the year 2018. Twenty five diverse genotypes of tomato comprising of eleven varieties, ten exotic lines and three local collections along with one standard check Solan Lalima were evaluated in Randomized Complete Block Design with three replications to ascertain extent of variability, heritability, genetic advance and gain, correlation and path coefficient analysis for yield and other horticultural traits along with the estimation of genetic divergence among the genotypes. Analysis of variance revealed significant differences among all the genotypes for all the characters under study. On the basis of overall performance, EC-802557, LC-2 and Arka Alok were found superior for marketable fruit yield and other important horticultural traits. They could be the promising parents for utilization in further breeding programmes. The estimates of PCV and GCV were high for marketable fruit yield per plant, number of locules per fruit, average fruit weight, harvest duration, shelf life and number of fruits per cluster. High heritability estimates were observed for all the traits among all genotypes while high estimates of genetic gain were observed for marketable fruit yield per plant, average fruit weight, harvest duration, shelf life, number of fruits per cluster, number of locules per fruit, number of fruits per plant, fruit breadth, pericarp thickness, number of fruit cluster per plant, fruit length and plant height. The correlation studies revealed that marketable fruit yield per plant had positive and significant correlation with fruit length, fruit breadth, average fruit weight, number of fruit clusters per plant, number of fruits per plant, number of locules per fruit, harvest duration, shelf life, pericarp thickness and total soluble solids. The path coefficient analysis revealed that maximum positive direct effect towards marketable fruit yield per plant was contributed by average fruit weight followed by fruit length, number of locules per fruit, fruit breadth and total soluble solids. Under genetic divergence studies, 25 genotypes were grouped in to five clusters and maximum inter cluster distance was recorded between cluster I and IV and lowest was observed between cluster I and V. Therefore, hybridization among the genotypes of cluster I and IV can be utilized to obtain superior hybrids or recombinants in later segregating generations.ThesisItem Open Access MAPPING OF FRUIT CROP DIVERSITY AND FROST VULNERABILITY USING GEO SPATIAL TOOLS IN BILASPUR DISTRICT(COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-12-14) MEHTA, HIMANSHU; SHARMA, SOM DEVThe present investigation entitled, “Mapping of fruit crop diversity and frost vulnerability using geo spatial tools in Bilaspur district” was carried out at Geoinformatics laboratory, Department of Fruit Science, College of Horticulture and Forestry Neri, Hamirpur (HP) during 2017 to 2019.

The experiment was laid out in randomized complete block design with three replications and 20 genotypes including check variety “Pusa Anupam” were planted for studying the extent of variability and performance of each genotype. The study revealed a significant difference among the genotypes for all the characters studied. A wide variability was observed for the characters in the genotypes. B-COHFNERI-9 (1.11 kg) followed by Arka Kusumkar (1.08 kg), Pusa Purple Cluster (0.97 kg), B-COHFNERI-4 (0.95 kg) and B-COHFNERI-2 (0.92 kg) recorded higher marketable fruit yield per plant as compared to the check variety, “Pusa Anupam” (0.81 kg). High magnitude of GCV and PCV were recorded for the traits like number of marketable fruits per plant, fruit length, stem diameter and weight of 100 seeds. High estimates of heritability and genetic advance were recorded for days to first picking, pedicel length, fruit length, average fruit weight, number of marketable fruits per plant, number of primary branches per plant, plant height, stem diameter, plant spread, weight of 100 seeds. Results also indicated that marketable fruit yield per plant had positive and significant correlation with days to 50% flowering, number of marketable fruits per plant and stem diameter. Further, path coefficient analysis revealed that number of marketable fruits per plant had maximum positive direct effect on marketable fruit yield per plant followed by fruit diameter and weight of 100 seeds. Thus, hybridization between the genotypes can be very effective for further improvement in brinjal.ThesisItem Open Access GENETIC EVALUATION OF LOCAL GENOTYPES OF OKRA (Abelmoschus esculentus (L.) Moench) UNDER LOW HILL CONDITIONS OF H.P.(COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-11-09) SHARMA, PRATIBHA; DOGRA, B SThe present investigation entitled “Genetic evaluation of local genotypes of okra (Abelmoschus esculentus ( L.) Moench.) under low hill conditions of H.P.” was conducted at Experimental Farm, Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (H.P.) during Rainy, 2018 to evaluate genotypes of Okra and to study variability, heritability, correlation and path analysis of different characters. The experiment was laid out in RCBD with three replications and 20 genotypes including two checks ‘P-8 and Palam Komal’ for studying the extent of genetic variability and performance of each genotype. The present investigated studies revealed a significant difference among genotypes for all the characters studied. Genotypes like LC-16-18, LC-1818, LC-11-18, LC-9-18 and LC-5-18 were significantly superior over other genotypes and both the respective checks for yield and few other horticultural important traits of vegetable types and can be recommended as such for direct cultivation after multilocational testing in the state. The GCV and PCV were high for traits like internodal length, fruit weight, number of seeds per fruit and fruit yield per plant. High heritability coupled with high genetic advance as percentage of mean was observed for plant height, first fruiting node, internodal length, fruit weight, fruit yield per plant, number of seeds per fruit, number of fruits per plant, number of locules per fruit, fruit length and fruit diameter which indicates their improvement through simple selection method. Correlation analysis revealed that traits like fruit weight, 100 seed weight, number of seeds per fruit, fruit length, fruit diameter and number of fruits per plant had significant positive correlation with fruit yield per plant at both phenotypic and genotypic level. Further, path coefficient analysis suggested that fruit diameter had the highest positive direct effect on fruit yield per plant followed by 100 seed weight, fruit weight, first fruiting node, fruit length, number of fruits per plant and internodal length. Therefore, main emphasis should be given on these characters, while making selection in okra genotypes.ThesisItem Open Access EXPLORATION OF GENETIC VARIABILITY IN CHILLI (Capsicum annuum L.)
