Abstract:
The genetic parameters like PCV, GCV, heritability and genetic advance as percent of mean were generated using appropriate breeding and biometrical approaches for high yield and yield contributing traits in the F₂ population of four crosses (VRMM-310 × VRMM-37, VRMM-35 × VRMM-29, VRMM-310 × VRMM-7, VRMM-37 × VRMM-7), these crosses referred to as cross 1, 2, 3 and 4. Higher genotypic and phenotypic coefficients of variation, as well as high heritability estimates, were observed for the yield of fruit per vine in all four crosses; for the weight of fruit, average diameter in crosses 1, 2, and 4; and for average pulp thickness in crosses 2 and 4, indicating the existence of more variability and additive gene effects among all the traits that can be enhanced by the simple selection.
