Character association and path analysis for fruit yield and it’s contributing traits in cucumber genotypes (Cucumis sativus L.) under naturally ventilated polyhouse during off season

2019 
Ten cucumber genotypes were evaluated at B.C.K.V. under naturally ventilated polyhouse during 2016-17. This study was conducted to examine relationship between important traits of cucumber and their direct and indirect effects on yield. The relationships between fruit yield and yield components in cucumber genotypes were investigated as well as how those relationships changed with selection for improved fruit yield. In this study, genotypic correlation was higher than phenotypic correlations indicating the highly heritable nature of the traits. Correlation studies revealed that intermodal length has exhibited highly significant positive association with fruit yield per plant followed by fruit length, fruit weight, number of fruits per plant and vine length. Direct selection based on these traits would improve yield. The path coefficient analysis revealed that the days to fifty percent flowering, number of fruits per vine, internodal length, fruit weight, fruit length, fruit diameter, TSS and moisture percentage have direct positive phenotypic and genotypic effect on yield. Future breeding should focus on selecting the characters having direct effects to improve yield per plot.
