【摘要】 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。更多还原

【Abstract】 In March and August, 1978, we achieved two self-pollinated and fruitful pure diploids by anther culture in vitro, amounting to 115 seeds. Seeds from first plant was sown in May in field for observation of progenies with their parents. In Feb-ruary and March 1979, we achieved five self-pollinated and fruitful plants five self-pollinated plants between lines, and one cross-pollinated plant.Experiment proves that the second generation (H2) of plants from anther culture in vitro are almost similar. We have received 47 pure lines, and at the same time determined the crossing ability of them. A comparison of genetic characters has also been made between the progenies and their parents.更多还原
