Abstract


The pattern of transgressive segregation in the crosses was positive in respect of days to flowering, panicle length, grain number per panicle and 100 grain weight, while it showed a negative trend for plant height. Early duration and high yielding segregants were predominant in the cross, Co 37/ADT 16. Four crosses viz., ADT 16/Co 33, Co 33/ADT 16, Co 37/ADT 16 and ADT 16/Co 37 recorded high percentage of late duration and high yielding segregants, while the cross Co 33/ADT 16 yielded a large number of transgressive segregants with profuse tillering, increased number of grains, high grain weight and high yield.
