Germplasm Under Tarai region of Uttarakhand " was conducted at Vegetable Research Centre G. B. Pant University of Agriculture and Technology, Pantnagar ( Uttarakhand) during rabi season of 2018-19. The experiment was laid out in Augmented Block Design II consisting of fifty four genotypes including three checks viz., Pant Uphar, PSM-3 and PSM-6. During the study, observations are recorded for twelve growth, yield and two quality characters viz., days to 50% germination, days to 1st picking, numbers of pods per plant, avg. Pod weight, pod diameter, pod length, numbers of seeds per pod, weight of green seed per pod, shelling percentage, plant height, yield per hectare, TSS (total soluble solids), foliage color, pod color, pod curvature, mature seed shape. The study on variability, heritability in broad sense, genetic advance as percentage of mean, correlation and path coefficient analysis were carried out. Analysis of variance revealed that all the characters under study showed highly significant differences. High heritability in broad sense along with high genetic advance as percentage of mean were observed for the traits viz., yield per hectare, plant height and shelling percentage. Based on results, it was found that the characters like pod length, days to 50% flowering, number of pods per plant, weight of green seeds per pod, shelling percentage were found to be highly significantly associated with pod yield per hectare at both genotypic and phenotypic level. The higher magnitude of genotypic and phenotypic positive direct effect on pod yield per hectare was observed for weight of green seed per pod followed by pod diameter, number of seed per pod, shelling percentage, plant height. Among the check varieties, PSM-6 gave higher yield than Pant Uphar followed by PSM-3. Based on the present investigation, the early maturing and high yielding genotypes viz., PM-98, PM-204 were promising and can be recommended for direct commercial cultivation in the tarai area of Uttarakhand.EnglishThesis
