Inheritance of white rust resistance in Indian mustard (Brassica uncea L.) Czern Coss

摘要

Inheritance of white rust resistance in P1, P2, F1, F2 and backcross generation of two crosses of Brassica juncea revealed that one gene with complete dominance conferred resistance to white rust. A segregation ratio of 3 resistant: 1 susceptible in F2 generations of these crosses further confirmed that white rust resistance is governed by a single dominant gene which can easily be transferred by backcrossing from a resistant to susceptible genotypes.
