Study of variability and morphological characterization of cultivated genotypes of bottle gourd [Lagenaria siceraria (Mol.) Stdl.]

Abstract

A field experiment was conducted to assess the variability and morphological characterization of bottle gourd genotypes which comprises of 37 genotypes at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during summer. The genotypes were planted in randomized block design with three replications. The data recorded were subjected to statistical analysis. Considerable amount of variability was noticed for the 16 quantitative traits as indicated by the analysis of variance. High estimates of GCV and PCV were recorded for diameter of fruit, length of fruit, weight of 100 seeds, no. of fruits per vine, number of primary branches, nodes to first male flower, fruit yield per vine, leaf length, nodes to first female flower and fruit yield per vine. High heritability coupled with high genetic advance as percent of mean was observed for diameter of fruit, length of fruit and weight of hundred seed that these traits were under the strong influence of additive gene action.
