摘　　要：对单倍体诱导系Stock6进行改良,从Stock6与M278的杂交后代中连续6代测交和选择,育成了高频率单倍体诱导系吉高诱系3号。通过对20个不同基因型材料的单倍体诱导结果表明,单倍体诱导率介于5.50%～15.94%,平均单倍体诱导率为10.40%,是Stock6的10倍;子粒Navajo标记性状明显、稳定,花粉量大、结实性好、抗病性强,是优良的单倍体诱导系。We developed JAAS3 which is the high frequency haploid inducer through the improvement of haploid inducer Stock6, testerosses 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.
