Abstract:
The female parthenogenesis on the male-sterile plants of Taigu genic male-sterile wheat and dwarf abortion wheat were induced by norethindrone, megestrolum, diethylstilbestrol,maleic hydrazide (MH) and so on in isolation conditions. The results indicated that induced seed setting rate of Taigu genic male-sterile wheat was higher than that of dwarf abortion wheat.Norethindrone, megestrolum and diethylstilbestrol yielded higher induced seed setting rate than maleic hydrazide. The chemical treatment after glume-cutting could help to raise the induced seed-setting rate, so did bagging after chemical treatment. The suitable time for chemical treatment was 19: 00 pm. The induction effects on different materials varied with changes of the number of chemical treatments.
Key words:
