利用2006～2010年间山东、河南玉米区域试验报告,对通过审定的普通夏玉米品种的数量、千粒重、出籽率、生育期以及产量增幅(比对照)进行了对比分析。结果表明:山东、河南两省其间审定的普通夏玉米品种类型多样,产量有较大提升,说明育种水平有了大的提高,在注重提高出籽率的基础上,很好地解决了生育期与产量的协调关系;山东省审定品种的产量水平有待进一步提升,应加强育种技术与方法的改进。
Based on the regional test report of Shandong and Henan maize from 2006 to 2010, the comparative analysis was conducted on the quantity, 1000-grain weight, the seed yield, the growth period and the yield increase (compared with the control) of the certified summer maize varieties. The results showed that the varieties of common summer maize validated in Shandong and Henan Provinces were diverse and the yield was greatly improved, which indicated that the breeding level had been greatly improved. On the basis of paying more attention to improving the seed yield, And the coordination of production; Shandong Province, the certified varieties of the yield level needs to be further improved, breeding techniques and methods should be strengthened to improve.
