Inheritance of white rust resistance was studied in two crosses between resistant (R) and sensitive (S) types of Brassica juncea , namely EC 12749 בParkash’ (R × S) and EC 12749 בVaruna’ (R × S) under conditions of normal and late sowing. Analysis of six generations revealed the importance of additive, dominant and epistatic effects. Disease was more prevalent under late sowing due to favourable environment. Reciprocal recurrent selection is advocated for exploiting the additive and non‐additive gene effects for resistance to white rust.
