| 摘 要： | 根据大刍草形态学性状的显著区别，大刍草可分为5个植物学种。大刍草是玉米亲缘关系最近的野生近缘材料已被众多研究结果证实，玉米的直接祖先是否是大刍草还没有定论。对玉米与大刍草的分类系统作了介绍，同时对5个大刍草植物学种的特征特性、玉米与摩擦禾分类作了描述。

| Abstract: | We developed JAAS3 which is the high frequency haploid inducer through the improvement of haploid inducer Stock6, testcrosses and selections of successive six generations from the hybrids between Stock6 and M278.The induction results of 20 haploid inducers with different genotypes showed that the induction rate of haploid was from 5.50% to 15.94%, the average induction rate of haploid was 10.4%, about 10 times as that induced by Stock6. JAAS3 has a more obvious Navajo marker, large pollen shedding and strong resistance. It is a good material for haploid induction. |
