| Abstract: | In order to screen the new hybrid maize varieties suitable for planting after natural disasters in Hunan double rice field,25 new varieties of hybrid corn with large planting area or newly released varieties in recent years were used as test material.The high yield,adaptability,growth period and stress resistance of new varieties were used to analyze by the partition compares method designing.The results indicated that the average yield of the tested varieties amounted to 7.25 t / hm2.Thirteen varieties had an increase of more than 10% over check variety（Lin’ao 1）.The varieties with high yield,good comprehensive characters were Keyu 2、Dong 315、Xiangkangyu 2、Sanbei 2、Xiangkangyu 2、Keyu6、Luoyu 1 and Fengyu8,which enter into the next year ＇s corn varieties screening test for screening appropriate post-disaster remedy maize varieties. |
