利用引进的玉米单倍体诱导系RWS、Stock6、高诱1号以及用其杂交改良选育的诱导系,对不同基因型玉米单倍体诱导效果进行了初步研究。结果表明:以诱导系Stock6为父本时,材料2005的诱导率最高为2.85%;以诱导系RWS、Stock6、高诱1号以及他们杂交改良选育的诱导系为诱导父本时,不同基因型玉米单倍体诱导率差异明显,诱导系2061、2062、2058和2059诱导率相对较高,可以重点利用;选择诱导材料时要根据育种的目的组建不同的母本基础材料。
The haploid induction lines RWS, Stock6 and GAOYU1 of maize introduced and their inbred lines improved by crossbreeding were used to study the induction effects of different genotypes of maize haploid. The results showed that the highest induction rate of material 2005 was 2.85% when Stock6 was used as the male parent. When the induction lines of RWS, Stock6 and GAOYU1 were used as male parents, the induction rate of different genes The maize haploid induction rate was significantly different. The induction rates of 2061, 2062, 2058 and 2059 were relatively high, which could be used intensively. When choosing inducing materials, different maternal basal materials should be set up according to breeding purposes.
