In order to improve and apply the haploid inducers of different blood backgrounds clearly, in this study,21 introduced and self-selective haploid inducers were selected, and Geno Plexs multiplex PCR-based 1 K SNPmarkers were used for genotyping and hierarchical clustering was used for group classification.’Xianyu 335’ and 3 waxy hybrids were used as a female parent to induce hybridization to judge the inducing ability of the haploid induc-ers. The results showed that 21 induction lines were classified into three types of blood, among which group Ⅰ repre-sented by Stock6, group Ⅱ represented by ‘Jiyou 101’, and group Ⅲ represented by the CAUHO. The average in-ducing rate of group Ⅱ was significantly higher than group Ⅲ and group Ⅰ. The self-selected lines,’Jiyou 101’ andWY7 produced an induction rate gain compared to the background haploid inducers during the selection process.WY7 and W7-4 can be used to induce waxy corn.
