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 CHARACTERIZATION AND EVALUATION OF FRENCH BEAN (Phaseolus vulgaris L.) GERMPLASM OF HIMACHAL PRADESH
    (UHF,NAUNI, 2017) KANWAR, RAJESH; MEHTA, D.K.
    ABSTRACT Knowledge of genetic diversity is important for selection of parents in the crop improvement programmes and to develop a sustainable conservation strategy. The present investigation entitled “Studies on characterization and evaluation of French bean (Phaseolus vulgaris l.) germplasm of Himachal Pradesh” was conducted in the years 2014, 2015 and 2016 to decipher the French bean diversity of Himachal Pradesh through varietal characterization and also aimed to evaluate the performance of different French bean genotypes for seed yield and other agronomical attributes. In total 26 geographically diverse French bean genotypes collected from different agro-climatic zones of Himachal Pradesh and two check varieties viz., Baspa and Jawala were utilized in the study. The genotypes were subjected to preliminary seed morphometric characterization in the Laboratory and field evaluation in the Experimental farm using qualitative and quantitative traits. Analysis of seed morphometric traits revealed ample amount of variability with respect to seed coat colour, seed shape, 100 seed weight, seed length and seed width. The field experiment was laid out in Randomized Complete Block Design with three replications for studying the extent of variability and performance of each genotype. Observations were recorded on eleven qualitative and fifteen quantitative traits. Amongst the qualitative traits, French bean genotypes observed variability w.r.t. plant growth habit, stem pigmentation, hairiness on the stem, flower colour, pod colour at immature stage and pod shape. Analysis of variance for quantitative traits showed significant differences among all the genotypes for all the characters studied. The genotypes RL-19 and RL-20 gave higher seed yield and performed better for many of the horticultural traits over all the checks. The genotypic variance was low to high for different traits studied, which resulted in low to high heritability and genetic gain values. High heritability coupled with high genetic gain was observed for plant height at final harvest, number of branches per plant, number of pods per plant, 100 seed weight and seed yield /plant which suggests their improvement through simple selection method. Correlation analysis revealed that all the traits except pod width had significant positive correlation with seed yield per plant at both phenotypic and genotypic level. Further, path coefficient analysis indicated that pod length had the highest positive direct effect on seed yield/plant followed by number of seeds per pod, number of pods per plant, days to 50% flowering, number of branches per plant, leaflet width, harvest duration, plant height at final harvest and 100 seed weight. Therefore, main emphasis should be given on these characters, while making selection in French bean genotypes. D2 Mahalanobis analysis divided the genotypes into three clusters and revealed that the cluster I and II were most divergent and there will be more chances of getting better segregants in F2 and subsequent generations from the crossing of genotypes from cluster I and II. Thus, hybridization between the genotypes of these groups can be very effective for further improvement in French bean. Moreover, 15 RAPD primers were used for deducing the diversity at DNA level. The French bean genotypes produced 79 PCR fragments, of which 59 were polymorphic with an average of 3.93 polymorphic bands per primer. The level of polymorphism with different primers ranged between 42.86-100%. The average Jaccard similarity index among genotypes ranged from 0.48 to 0.98, thereby showing sufficient genetic variability. Dendrogram generated via RAPD information separated majority of the genotypes in two sub clusters (Ia and Ib) sharing approximately 68% similarity between each other. Further, genotype RL-21 followed by RL- 18, RL-17 and RL-22 came as an outliner falling individually in distinct indexing pattern. Geographical affiliations and morphological associations were observed while studying the genotypic patterns within each group i.e. A, B, C and D, thereby conforming the usefulness of PCR based approach in diversity assessment. Thus, the present study indicated that the collected landraces had sufficient variability both at morphological and molecular level. Such variability is desirable in breeding programs.

    STUDIES ON SEED PRIMING IN BITTER GOURD (Momordica charantia L.)
    (2013) KANWAR, RAJESH; KANWAR, H.S.
    ABSTRACT The present investigations “Studies on seed priming in bitter gourd (Momordica charantia L.)’’ were carried out in the laboratory and Khaltoo experimental farm of Seed Technology and Production Centre, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan, HP during the year 2012-13 using cultivar ‘Solan Hara’. The research was conducted in three experiments. Experiment I (Preliminary studies) was laid out in Completely Randomized Design (CRD) in paper towel and sand method. Two vigour groups of seeds viz., ‘V1’ (High vigour seeds) and ‘V2’ (72 hours accelerated aged seeds/low vigour seeds) and nine seed priming treatments viz., ‘P1’ (Osmopriming with PEG 6000 -1.0 MPa), ‘P2’ (Halopriming with KNO3 @ 1%), ‘P3’ (Halopriming with KH2PO4 @ 1%), ‘P4’ (Halopriming with CuSO4 @ 100ppm), ‘P5’ (Solid matrix priming with Cocopeat), ‘P6’ (Solid matrix priming with Perlite), ‘P7’ (Solid matrix priming with Vermiculite), ‘P8’ (Seed soaking in water), ‘P9’ (Control -Without treatment) were used. Based on the observations on germination percentage, seedling length, seedling dry weight and seedling vigour index I and II seeds primed with Perlite, Cocopeat and Vermiculite were extracted as three best treatments for conducting experiment II and III alongwith Seed soaking in water (Common farmer’s practice) and Control. Experiment II (Field performance) was carried out in the field from 29th April 2012 to 28th September 2012 in Randomized Block Design (RBD). The treatments comprised of two vigour groups of seeds viz., ‘V1’ (High vigour seeds) and ‘V2’ (72 hours accelerated aged seeds/low vigour seeds) and five seed priming treatments viz., ‘P1’ (Solid matrix priming with Cocopeat), ‘P2’ (Solid matrix priming with Perlite), ‘P3’ (Solid matrix priming with Vermiculite), ‘P4’ (Seed soaking in water), ‘P5’ (Control -Without treatment).The observations were recorded on various emergence (%), growth and fruit yield characters. High vigour seeds primed with Perlite ‘V1P2’was found to be the best treatment for most of the traits understudy recording highest total field emergence (76.60%), fruit yield per plot (16.12 Kg) and per hectare (250.35 q). Experiment III (Storage studies) was carried out in the laboratory from 23rd April 2012 to 22nd April 2013 Completely Randomized Design (CRD). The germination and vigour of seeds were tested using paper towel method. The treatments comprised of two storage environments viz., ‘S1’ (Ambient condition) and ‘S2’ (Refrigerated condition 40C), two vigour groups of seeds viz., ‘V1’ (High vigour seeds) and ‘V2’ (72 hours accelerated aged seeds/low vigour seeds) and five seed priming treatments viz., ‘P1’ (Solid matrix priming with Cocopeat), ‘P2’ (Solid matrix priming with Perlite), ‘P3’ (Solid matrix priming with Vermiculite), ‘P4’ (Seed soaking in water), ‘P5’ (Control -Without treatment). The treated seeds were stored in Aluminium laminated pouches and germination and vigour of primed seeds were analyzed after one month, three months, six months, nine months and twelve months of storage. From the storage studies, it was concluded that primed seeds of bitter gourd can be stored for six months under refrigerated condition and for three months under ambient condition in both the vigour groups of seeds.
