自然界种子植物自发产生单倍体的现象早有发现,但频率很低。近年来,国内外开展了玉米花粉培养的单倍体育种试验,取得可喜成果。但用人工诱导玉米雌穗结实,报道不多。1980年中国遗传学会在广州召开的植物单性生殖学术交流会上,中国科学院遗传所、广西农校、河北通县农业局等单位报告了诱导玉米单性生殖的不同结果。1979年至1982年我们进行了这方面试验,目的是筛选能高频率诱发孤雌生殖的化学药剂和观察纯合二倍体的性状及其配合
Natural phenomenon of spontaneous haploid seed plants found long ago, but the frequency is low. In recent years, domestic and foreign carried out the haploid breeding test of corn pollen, and achieved gratifying results. However, with artificial induced corn ear strong, few reports. In 1980, the Chinese Genetics Society held a symposium on plant heritability in Guangzhou. Institutes of Genetics, Chinese Academy of Agricultural Sciences, Guangxi Agricultural School, Hebei Tongxian Bureau of Agriculture, and other units reported different results in inducing parthenogenesis in maize. From 1979 to 1982, we carried out experiments in this area to screen chemical agents capable of inducing parthenogenesis at high frequency and to observe the characteristics of homozygous diploid and their cooperation
