Genetics of flower colour in Indian mustard (Brassica juncea L. Czern and Coss)

Abstract

Bright yellow petal colour is the characteristic of family Brassicaceae, however the white petal flowers in mustard (Brassicajuncea L.) are often observed. White/ yellow petal colour, being distinct in phenotype, may be a useful morphological marker for many studies in breeding programmes. In the present investigation, white and yellow flowers were observed in F3 generation of a cross B 33 x Sanjucta asech. These plants were selfed and in the subsequent generatons (F4 -F7), near isogenic lines (NIL) with white and yellow colour were developed.
