Genetic variability, correlation and path analysis in bottle gourd (Lagenaria siceraria (Mol. Standl.) germplasm

The present investigation was conducted to determine the variability, heritability, genetic advance and correlation of fruit yield and ten different yield contributing characters in bottle gourd. Wide range of variation was observed for most of the characters like fruit yield/vine, fruit number/vine...
