Studies on genetic variability for yield and quality attributes in bottle gourd [Lagenaria siceraria (Mol.) Standl.]

Abstract

The estimates of phenotypic and genotypic coefficients of variation, heritability and genetic advance among yield, quality and its components characters in 36 parents and F1S of bottle gourd were worked out from the experiment conduct over two years at Department of Vegetable Science, N.D. University of Agriculture & Technology, Kumarganj, Faizabad. High degree of variations was observed for all the characters studied. Number of primary branches per plant, T.S.S., ascorbic acid, non-reducing sugar and dry matter showed high estimates of phenotypic and genotypic coefficients of variations, heritability and genetic advance in both the years. These results indicates preponderance of additive genetic components which will be help full for further developing bottle gourd genotypes possessing high yield with better quality.
