[Method] Three hightoil maize varieties were cultivated to pollinate three common maize varieties. [Result] The kemel yield of common maize was increased or changed slightly, and the embryo weight was increased significantly after they were pollinated with the pollen of hightoil maize. The kemel embryo percentage and protein content of common maizethigh oil maize hybrids were higher than those of common maize inbreds. [Conclusion] The growth and development of kernel embryos, as well as the kernel quality of common maize was improved by pollination with hightoil maize.展开更多

The results showed that the average fresh weight yield of each variety was 3 199.5~3 976.6 kg/667m^(2), among them, 5 varieties had an increase in the yield. Variety variation accounted for 10.51% of the total variation;experimental site variation accounted for 63.22% of the total variation;interaction effect variation between gene and environment accounted for 26.28% of the total variation;IPCA1 and IPCA2 variation accounted for 50.7% and 31.2% of the interaction variation, respectively;IPCA3 variation accounted for 7.25% of the interaction variation. g_4, g_8, g_9, g_10, g_11 and g_12 had better adaptability to e_1, e_2, e_6 and e_7;while g_1, g_2, g_3, g_5, g_6 and g_7 had better adaptability to e_3, e_4, e_5 and e_8. In consideration of yield, g_1(Huinongqing 2) and g_9(Xinyu 666) were silage maize varieties with high and stable yield;g_3(Hemuyu 905), g_8(Wuhuayu 3) and g_11(Liangdu 191) had general stability, and their yield was higher than that of the control;g_12(Jinduyu 999) had the worst stability and low yield.展开更多
