ABSTRACT

Correlation matrix among different parameters of twenty eight bottle gourd genotypes was studied. It revealed the significant variation among the genotypes for most of the parameters such as days to 1st male flowering (FMF) and female flowering  (FFF), 1st harvest (FH), sex ratio (M:F), single fruit weight (FW) and fruit diameter (FD), total yield (TY), number of fruits/plant. Total yield (TY) was positively correlated with 1st male flowering (FMF) and female flowering (FFF), 1st harvest (FH), sex ratio (M: F), single fruit weight (FW) and fruit diameter (FD). On the contrary, TY was highly negatively correlated with to edible maturity (EM) and fruits / plant (FPP). Fruits / plant also showed was significantly and negatively correlated with FMF, FFF and FH revealed that early flowering and harvesting accelerated the degree of fruit setting.

Key words: Lagenaria siceraria, correlation coefficient
