Correlation and path coefficient analysis in bottle gourd (Lagenaria siceraria (Mol.) Standl.)

Abstract

The present study was conducted with 20 bottle gourd genotypes sown in Randomized Block Design (RBD) with three replication in the year 2016-2017 to assess the nature and magnitude of association among yield and its contributing traits in bottle gourd. Correlation studies revealed that yield highly significant and positive correlation of fruit yield per vine with fruit length, fruit girth, average fruit weight and 100 seed weight but significant and negative correlation of yield per vine with number of fruits per vine were observed at genotypic level, indicating mutual association of these traits. The direct effect of number of fruits per vine, fruit length, fruit girth, 100 seed weight, days to first male flowering, days to first female flowering, days to first fruit harvest and node number of first female flower on yield was high in magnitude in bottle gourd.
