根据多点试验资料,通过高稳系数、丰产性参数、稳定性参数及抗旱系数的计算,对参试玉米品种高产稳产及抗旱生态适应性进行综合分析和评价.结果表明:品种间、试验地点间的玉米产量有极显著差异,参试品种对不同试验地点的适应性有显著差异;灌溉增加了所有参试玉米品种的产量.洛玉1号和俞单3号高产稳产性最好.丰产性参数很好地反映了品种间的丰产性差异,高稳系数则较全面地反映了玉米品种的高产稳产综合性能.方差和变异度与玉米品种的稳产性关系不密切.参试品种间的抗旱系数没有显著差异.

High-stabble coefficients, high-stable yield coefficients, drought resistance coefficients of maize varieties were calculated according to the experimental data from 4 sites. Then, the high-stable yield and drought resistance of maize varieties were analyzed comprehensively. The results indicated that there were significant differences in maize yields among varieties and experimental sites. There was significant difference in adaptability of maize varieties to environment. Irrigation increased the yields of all the tested varieties. Luoyu No. 1 and Yudan No.3 are the best varieties with high-s...
