Impact of hybridization and induced mutagenesis on variability of traits and resistance to fusarium wilt in Chickpea (Cicer arietmum L.)

Abstract

A high yielding and a late wilter variety Bheema was crossed to ICCV-10, also a high yielder but highly-resistant to wilt. The two parents are known to differ in respect of a single gene governing resistance to wilt. The F2 seeds of cross between Bheema and ICCV-10 were subjected to gamma irradiation. Simultaneously, F2 was also advanced to F3 generation. Besides, Bheema was also subjected to irradiation to look to the possibility of developing high yielding and disease resistant mutants. The F2M1 population proved to be highly potential in recovering higher frequency of high yielding and wilt resistant types than selfed (F3) and mutant (M2) populations.
