Evaluation of open-pollinated varieties and hybrids of cucumber for off-season production under naturally ventilated polyhouse

Abstract

Genetic variability, heritability in broad sense and expected genetic advance of fruit yield and twelve other characters were studied in eleven open pollinated varieties/ hybrids of cucumber. Significant differences among the genotypes were observed for all the characters except internodal length. Phenotypic coefficient of variation and genotypic coefficient of variation were found high for number of fruits per plant. Highest heritability in broad sense was recorded for number of fruits per plant and number of nodes on main shoot. High heritability coupled with high genetic advance as per cent of mean was observed for yield and number of primary branches per plant which indicated that these characters are more reliable for effective selection.
