Development of yellow seeded brown sarson (Brassica rapa L.) genotypes for temperate conditions of Kashmir

Abstract

The inheritance of yellow seed coat-colour in brown sarson (Brassica rapa L.) was investigated in two crosses involvingtwo brown sarson cultivars viz Gulchin and KOS-1 and a yellow seeded genotype Yellow Sarson-1.The segregatingpattern of seed coat colour in F2, BC1 and BC2 revealed the monogenic control of seed coat colour with black colourdominant over yellow colour. Five yellow seeded brown sarson populations(YBS) were constituted from BC2F3. All thepopulations had higher seed weight and seed oil content than Gulchin (check).YBS-2 was found promising over checkvariety in oil yield per ha by a margin of 22%. Developing yellow seeded varieties is an appropriate approach to enhanceoilseed productivity and meal quality in brown sarson.
