TAILIEUCHUNG - Inheritance pattern of quantitative characters in Brassica juncea

The genetic basis of variation in 10 X 10 diallel, diverse lines of Brassica juncea L. was examined. The parents were crossed in all possible combinations excluding reciprocals. The performance of 45 F1 hybrids and 10 parents were evaluated for number of seeds per siliqua, 1000 seed weight, seed yield per plant and oil content. Analysis of variance showed highly significant differences for these traits. The two scaling tests . joint regression analysis and analysis of (Wr + Vr) and (Wr-Vr) suggested the adequacy of genetic model for seeds per siliqua, 1000-seed weight and seed yield per plant. The estimated components of variation revealed that dominance genes were more pronounced than additive genes. | Inheritance pattern of quantitative characters in Brassica juncea
