To determine combining ability and heterosis analysis for seed yield and yield components, eight genotypes of Indian
mustard (Brassica juncea L.) were crossed using a line X tester design. A randomised block design with three replicates
was used after fifteen crossings, and their parents were assessed in the field. None of the cross combinations displayed
both positive and negative significant SCA effects for seed yield/plant, while the GCA impacts of the parents, IC-571655,
demonstrated positive significant effects for the majority of the characteristics. Each trait in the crosses underwent a
distinct analysis of variance, and the hybrids exhibited significant heterosis. According to estimations of heterosis and
per se performance, the most promising cross for seed yield/plant was IC-508692 x Ashirwad, which was followed by IC
424414 x Ashirwad, IC-571655 x CS 54, and IC-571655 x Ashirwad
