Gs. Yang et Td. Fu, GENETIC INVESTIGATION OF 3 LINES WITH RECESSIVE GENIC MALE-STERILITY IN BRASSICA-NAPUS L, Plant breeding, 116(3), 1997, pp. 296-298
The male sterility (ms) of three recessive genic ms lines, 117AB, S45A
B and 9012AB, was controlled in each case by two recessive male steril
ity genes. The genes responsible in 117AB and S45AB are the same, but
they are genetically different from those in 9012AB.
