摘    要:以2000~2009年山东省审定的普通玉米品种为材料,运用简单分析、相关分析和通径分析相结合的方法对其主要农艺性状进行分析.结果表明:玉米果穗秃尖长呈下降趋势,性状改良效果明显;较对照品种的增产幅度呈下降趋势,说明产量水平没有突破;出籽率与产量正相关(R =0.178),出籽率的增加对产量提高的贡献最大,直接通径系数为...

关 键 词:山东省  审定玉米品种  农艺性状  相关分析  通径分析

Abstract:The main agronomic characters of approved maize hybrids in Shandong Province from 2000 to 2009 were studied through simple analysis,correlation analysis and path analysis.The results showed that the bare tip length of maize ear showed decreasing trend,so its improving effect was obvious.But the increment of yield decreased compared with the contrast,which indicated there was no breakthrough in maize yield.The kernel rate and growth period positively correlated with the maize grain yield with the correlation...
