为获得抗玉米小斑病(H.maydis)T型小种的突变体,将F-7T(得克萨斯)品系的颖果进行诱变处理,在M_3和M_4中得到了不同类型的雄性不育性(Cornu等,1980)。这些突变体中,HmT抗生家系(A型胞质回复突变体)出现了一个由小穗不开花造成的雄性不育特殊
In order to obtain the mutant of T.maydis T race, the caryopsis of strain F-7T (Texas) was mutagenized to obtain different types of male sterility in M_3 and M_4 (Cornu et al., 1980). Among these mutants, the HmT antibiotic family (type A cytoplasmic reversion mutant) emerged as a male sterility caused by the non-flowering of spikelets
