Abstract:
The present study was carried out on 37 genotypes of Indian mustard, including 24 F_1s, 11 parents, and 2 checks. Design used for this experiment was Line x Tester mating design and evaluated in Rabi 2022–2023 at the Instructional Farm at the Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur. According to the findings, general combining ability contributed more to the total mean squares for all traits than did specialised combining ability, indicating that additive gene activity was more important in the inheritance of these traits. The results of the analysis of variance showed that all of the traits had significant mean squares due to genotypes, parents, crosses, and parents v/s crosses, with the exception of the length of the main branch and the oil content due to parents, the length of the main branch due to crosses, and the length of the siliqua due to parents v/s crosses. Both additive and non-additive gene action were involved in the inheritance of the majority of the characteristics, as shown by the significance of General combining ability mean squares for lines and testers and Specific combining ability mean squares.
