摘要: 01A3是河南省新乡市农业科学院选育的优良玉米自交系,具有配合力高、农艺性状好、结实性好、中早熟的特性。以01A3为基础材料选育了一系列衍生系,利用01A3和姊妹系A01、新6及其衍生系选育了较多的优良玉米杂交种。01A3也存在缺陷,可对其改良再利用。

关键词: 玉米, 自交系, 01A3, 姊妹系, 衍生系, 选育

Abstract: 01A3 is an excellent maize inbred line bred by Xinxiang Academy of Agricultural Sciences, Henan Province. It has the characteristics of high combining ability, good agronomic traits, good firmness, and mid-early maturity. A series of derivative lines were selected based on 01A3, and more excellent corn hybrids were selected using 01A3 and sister lines A01, Xin6 and their derivative lines. 01A3 also has defects and can be improved and reused.

Key words: maize, inbred line, 01A3, sister line, derivative line, selective breeding
