ABSTRACT
An investigation was carried out with nineteen genotypes of cucumber to study the nature and magnitude of genetic variability among them by considering twenty one traits at the Vegetable Research Farm of Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during Kharif 2016. High estimates of PCV and GCV were obtained for traits like number of node at which first pistillate flower appears, fruit yield (q/ha), fruit length while the moderate value was recorded for the traits like average fruit weight indicated a good deal of variability in those characters signifying the effectiveness of selection of desirable types for improvement of such characters will be rewarding. Heritability and genetic advance are important selection parameters and selection success is a reflectance of selection response. Heritability estimates along with genetic advance are normally more helpful in predicting the gain under selection than heritability estimates alone. High heritability coupled with high genetic advance as percentage of mean were observed for number of node at which first pistillate flower appears followed by fruit yield (q/ha), fruit length, average fruit weight, test weight, number of fruits per plant, number of nodes per vine, number of primary branches per vine, etc., indicating predominance of additive gene action for these characters. Hence, simple selection based on phenotypic performance of these characters would be more effective.
Key words: Cucumis sativus L., Genetic variability, Heritability, Genetic advance, Yield traits
