中国人. 利用农大高诱1号对玉米不同种质和世代单倍体诱导频率的研究表明，农大高诱1号对塘四平头、旅大红骨、Laneaster、Reid4大种质类群和热导地方种质群的平均诱导率为3．9％，不同类群间存在显著差异。对Laneaster和Reid类群单倍体诱导率最高，为4．85％；对塘四平头和旅大红骨类群单倍体诱导率为3．95％；对热导地方种质群单倍体诱导率最低，为2．04％。农大高诱1号对同一群体不同世代间诱导率结果表明，一般高世代S4、S5，单倍体诱导率高，但每株单倍体粒数较低；S1代单倍体诱导率较低，但材料种穗大，实际得到的单倍体数量最多。早代S1代为最佳诱导单倍体世代。[著者文摘]

The result showed that the average induction rate of Tang 4, Luda, Lancaster, Reid groups and thermal conductivity local gerrnplasm five groups induced by Cauho Inducer 1 was 3.9%, but there were significant differences between different groups. Lancaster and Reid groups which haploid induced rate was 4.85% had the highest haploid induced rate than the other group, Inducement haploids frequency of Tang 4 and Luda group was 3.95%, thermal con- ductivity local germplasm group has 2.04% inducement haploids frequency. The rate of induction by Cauho Inducer 1 induced the same groups of different inter-generational survey results showed, the high generations S4, S5 had high haploid induced rate, but lower grains per plant. S1 had the lower induction rate, but had bigger corn ear, actually receive the largest number of haploid, so the best induction haploid generation is early generation S1.
