dc.description.abstractABSTRACT Globally, cucumber (Cucumis sativus L.) is the second most widely cultivated Cucurbit after watermelon. The present investigation entitled “Genetic studies for yield and quality traits in Cucumber (Cucumis sativus L.)” was carried out at Experimental Research Farm, Department of Vegetable Science, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) during Kharif, 2015. Thirty genotypes including check variety K-75 were evaluated to ascertain extent of variability, correlation and path coefficient analysis for yield and other horticultural traits along with estimation of genetic divergence among the genotypes. The experiment was laid out in a Randomized Complete Block Design with three replications. Analysis of variance showed significant difference among all the genotypes for all characters under study. Six genotypes namely, LC-2, LC-7, LC-9, LC-10, LC-15 and LC-27 gave sufficiently higher fruit yield, performed better with respect to other horticultural traits and showed lesser severity the diseases viz. angular leaf spot, anthracnose, downy mildew and powdery mildew over the standard check K-75. High estimates of heritability coupled with high genetic gain was depicted for node number bearing first female flower, number of fruits per plant, number of marketable fruits per plant, number of primary branches per plant, hundred seed weight, seed vigour index I, severity of angular leaf spot, severity of anthracnose, severity of downy mildew, severity of powdery mildew, yield per plot and yield per hectare. Yield was significantly and positively correlated with average fruit length, fruit diameter, number of marketable fruits per plant, harvest duration, vine length, number of primary branches per plant, seed length, hundred seed weight, germination percentage, vigour index I and II. Path analysis revealed that harvest duration had maximum positive direct effect on yield followed by vigour index II and marketable fruits per plant. Genetic divergence studies revealed that hybridization between genotypes of cluster II and V will be more rewarding for getting superior progeny(s).en_US
