A study on understanding the inheritance of yield and its related traits in bitter gourd by using generation means analysis involving six generations in two crosses (IC-044417×IC-045339 and IC-045339×IC-470560) revealed the presence of non-allelic interaction effects in expression of all the traits studied. All the traits were inherited by dominance (h) among the main effects and additive×additive (i) among the interaction effects in IC-044417×IC-045339 while dominance, additive×additive (i) and additive×dominance (j) in IC-045339×IC-470560 except fruit girth which was inherited by dominance (h) and dominance×dominance (l) type of interaction effect. Therefore, recurrent selection and diallel selective mating system in addition to heterosis breeding may be used to improve the traits in bitter gourd.
