Abstract

Twenty genotypes of mustard collected from diverse sources were grown and investigated for self-incompatibility at the Bangabandhu Sheikh MujiburRahman Agricultural University, Gazipur 1703, Bangladesh during rabi season of 1997-98. Seed set analysis were used to identify the self- incompatibility mechanism which indicated that the genotype Safal, Binasarisha-3, SS-75, Vardon, Na- 8509, Dhali, Daulat, Seeta, Kranti, Rai-5, Nap-3142, Jun-3018, Jun-4008, Nap-3015 and PT-30 were classed as self-compatible; while intermediate fertility were observed for TS-72, PT-303, M-27 and Tori-7 as those four genotypes showed more than 10 percent but less than 50 percent seed set ratio. Self-incompatibility study indicated that none of the genotypes under study was found full self- incompatible.
