我们利用花药培养法,于1978年3月和8月份获得两棵自交结实的玉米花粉植株,共得种子115粒。其中一株在同年5月份种人大田,进行后代与亲本的比较观察。 于1979年2、3月份又获得5株自交结实、5株互交结实和一株异交结实的花粉植株。实验表明,玉米花粉植株二代基本整齐一致,得到纯系47株。同时进行了配合力的测定,对花粉植株后代与亲本的遗传性状作了比较分析。
Using anther culture, we obtained two self-harvested corn pollen plants in March and August 1978 for a total of 115 seeds. One of them in the same year in May of the kind of field, the offspring and the parental comparative observation. In February and March 1979, another 5 self-pollinated and 5 pollinated and one outcrossed pollen plants were obtained. Experiments show that corn pollen plants two generations basically the same, get pure line 47. At the same time, the determination of combining ability was carried out, and the genetic characters of pollen plants were compared with those of their parents.
