摘要
This study aimed to investigate the induction effect on different genotypes of maize of haploid inducers RWS, Stock6, CAU Inducer and hybridization-derived breeding lines. The results showed that 2005 had the highest induction rate （2.85%） when using inducer Stock6 as male parent material; haploid induction rates were significantly different among different genotypes of maize when using RWS, Stock6, CAU Inducer and their crossbreeding materials as the male parents; inducers 2061, 2062, 2058 and 2059 led to relatively high induction rates, which could be emphatically utilized. Furthermore, during the screening of induction materials, different female parent materials should be selected based on the breeding objective.
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。
