tailieunhanh - Restorers and maintainers of A2 and A4 cytoplasm-based CMS lines in pigeonpea
In the present investigation, 78 genotypes were evaluated for their fertility restoration or sterility maintenance behaviour with two A2 cytoplasm-based CMS lines (BRG 1A and Hy 3CA) and 36 genotypes with three A4 cytoplasm-based CMS lines (BRG 1A, Hy 3CA and BRG 3A) in pigeonpea during 2012 and 2013. It was observed that 16 genotypes viz., GCB 4, GCB 15, GCB 18, GCB 45, GCB 50, GCB 55, GCB 61, GCB 68, ICPL 87119, GRG 206, GRG 215, GRG 818, JKM 207, WRP 1, BDN 2 and BDN 2010 restored fertility of both A2 cytoplasm-based CMS lines viz., BRG 1A and Hy 3CA while three genotypes viz., ICPL 20116, ICPL 20093 and BRGL 13-171 restored fertility of all the three A4 cytoplasm- based CMS lines viz., BRG 1A, Hy 3CA and BRG 3A. The identified restorers and maintainers could be further utilized in developing new restorer lines/hybrids and CMS lines, respectively. | Restorers and maintainers of A2 and A4 cytoplasm-based CMS lines in pigeonpea
