| 摘 要： | 玉米优异核心种质5003及其姊妹系5005是我国第一个自主选育的多基因控制的矮源资源。5003(5005)及其衍生自交系适应性广、抗逆性强、配合力高,与国内外主要种质类群均有明显杂种优势,构成了新的矮生杂种优势群。从20世纪80年代至今,全国各地育种单位育成含有5003(5005)种质的优良自交系25个,配出年推广面积超过10万hm2以上的玉米杂交种有38个,累计推广面积达1.08亿hm2。

| Abstract: | An elite maize inbred 5003 and its sister line 5005 were important core dwarf germplasm source,which was controlled by multigenic genes.5003 as well as derived elite inbreds had widely adaptability,high stress tolerances and high combining ability with other heterosis groups,which consists of a new dwarf heterosis group.Since 1980's,twenty five of derived elite inbreds were bred using 5003 as germplasm source and 38 hybrids planted over 100 thousand hectares were combined by those inbreds.The total planting areas of those hybrids reached to 108 million hectares in China. |
