摘　　要：以四大基本模式(唐四平头类群内改良、唐四平头类×P群、唐四平头类×兰卡斯特、唐四平头类×旅大红骨)为基本材料,探讨改良诱导系XKY-1、XKY-2对唐四平头类种质的诱导效果,同时用组织培养方法对单倍体加倍进行了探索。结果表明,2个诱导系对唐四平头类种质的诱导率平均达6%以上,加倍率可以达到20%。该研究为开展单倍体育种提供了参考依据。With four patterns(TangSPT×TangSPT,TangSPT×p,TangSPT×Lancaster and TangSPT×Lvdahonggu)as the basic materials,we discussed the induction effects of improved inducers XKY-1 and XKY-2.And the haploid doubling was explored by tissue culture method.Results showed that the average induction rates of improved inducers were above 6%,and the average doubling rate was about 20%.The research provided references for haploid breeding of maize.
