Bright yellow petal colour is the characteristic of family Brassicaceae, however the white petal flowers in mustard (Brassica juncea 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. Crosses between yellow flowered and white flowered plants were attempted during 2005-06 and subsequently (during 2005-06 to 2007-08), F1, F2, BC1 (F1 x yellow) and BC2 (P1 x white flower) generations were developed. These generations (P1, P2, F1, F2, BC1, and BC2) were grown during 2008-09 and observations on flower colour were recorded. Data recorded for number of white/yellow flowered plants were subjected for statistical analyses and the x2 values were calculated.
