| 摘 要： | 53自交系是利用9个优良自交系组成基础群体,经两次开放传粉后自交选育而成.试验示范结果表明,53高抗大小斑病和青枯病,抗玉米丝黑穗病,中抗玉米矮花叶病及粗缩病,配合力高,自身产量高,生育期适中,受到省内外育种家关注.据不完全统计,在河北、河南、山西和云南等省以53及其改良系作亲本已育成11个通过审定的杂交种.其中河北省的冀丰58及河南省的豫玉27在省内外累计推广面积达900万hm2。

| Abstract: | The 53 maize inbred line was bred from nine fine maize inbred lines, which constitute foundation colony, through two generation open-pollination, and then self-pollination. The results of experiment showed that 53 is high-resistant to leaf spot, leaf blight and bacterial, resistant to maize head smut, middle-resistant to rough dwarf and mosaic disease, it is good of combining ability and self-output and appropriate growing period. Because of its good characters,it is noticed by more and more breeding experts of Hebei or the other provinces. According to the statistics there have been at least eleven examined maize hybrids used 53 or its improved-line as parents in Hebei, Henan, Shanxi and Yunnan provinces. Especially the hybrid Jifeng 58 bred by Hebei and the hybrid Yuyu 27 bred by Henan have aleady covered for most large areas. Up to now all the hybrids used 53 or its improved-line as parents have covered at least 9 000 000 ha plantation areas. |
