玉米为异花授粉作物,利用杂交优势能大幅度提高产量,玉米双交种或单交种所需的自交系,要较长的时间才能获得,而单倍体植株加倍获得的纯合二倍体即为自交系。因此如能用花药培养出植株,一年就可获得较多的自交系。1976年,我们进行了多种试验,取得了一定成效。愈伤组织诱导培养基为4种,接种材料为单核后期,用直接投入法接种。绿苗分化培养基一种, Maize cross-pollination crops, the use of hybrids can greatly improve the yield, maize double cross or single cross-breeding needs of inbred lines, it takes a long time to obtain, and haploid plants doubling obtained homozygous two Ploidy is the inbred line. Therefore, if the plants can be cultured with anther, a year can get more inbred lines. In 1976, we conducted various tests and achieved some success. Four kinds of callus induction medium were used, and the inoculation material was mononuclear, and inoculated directly into the medium. A green shoot differentiation medium,
