为研究化学药剂诱导玉米孤雌生殖获得纯系的可操作性,选取6个自交系组建唐四平头群体,从不同诱导时间和不同化学药剂2个方面探讨最佳诱导条件,并对孤雌生殖系后代进行稳定性和配合力分析。结果表明:最佳诱导时间为雌穗吐丝3d,诱导率为0.098%;0.20mg·kg-1 Col诱导率最高,诱导率为0.192%,比对照(0.023%)高8.3倍;通过田间表型鉴定及自交,共获得玉米孤雌株系112份;从各个组合一般配合力和特殊配合力的相对平均值来看,P1亲本中T239和T298特殊配合力表现最好。 In order to study the maneuverability of chemical-induced maize parthenogenesis to obtain pure lines, six inbred lines were selected to establish Tangsipingtou population. The optimal induction conditions were explored from two different induction time and different chemical agents, Analysis of the stability and combining ability of germplasm offspring. The results showed that the best induction time was 3d in silkworm spawning, and the induction rate was 0.098%. The highest induction rate of Col was 0.20mg · kg-1, the induction rate was 0.192%, which was 8.3 times higher than that of the control (0.023%); Type identification and selfing, a total of 112 parts of maize parthenocarpy were obtained. From the relative average of the general combining ability and the special combining ability, the F1 combining ability of T239 and T298 showed the best performance.
