Abstract
Spontaneously developed ‘C’ genome substitution lines of Brassica juncea (L.) Coss were identified in the F7 generation of an interspecific cross between B. juncea (AABB; 2n=36) and B. napus (AACC; 2n=38). These lines were meiotically stable (2n=36) and had normal male and female fertility. They were characterized by certain specific traits like bolting habit, leaf aberrations and variation for erucic acid content. Cytological evidence indicated that at least three lines has substitution for different chromosomes. The substitution stocks characterized in this study are important for their use in practical crop breeding and certain basic genetic studies.
