小麦新品种(系)产量及其与主要产量性状的相关性

Correlations between Yield and Main Yield-related Traits of New Developed Wheat Varieties(Lines)

2010-2011年在安徽省六安市农科院进行国家小麦新品种(系)区域试验(长江中下游组),结果表明,参试12个小麦新品种(系)中,扬辐7091、镇08066、庆丰188产量较高,分别为6 472.2、6 449.7和6 408.6kg/hm2,分别较对照扬麦158增产8.24%、7.87%和7.18%,且抗病、抗倒伏能力均较强,株高适宜,生育期与对照基本相当,综合性状优良,建议进入下一年度区域试验。主成分分析和偏相关分析表明,小麦有效穗数是影响产量的主要因素。

National regional experiment on new wheat varieties（lines）of 2010-2011 in Liu＇an pilot showed that：in 12 new wheat varieties（lines）,Yangfu 7091,Zhen 08066 and Qingfeng 188 characterized appropriate plants height,resistant to disease and lodging,and similar growth period to the control.They yielded 6 472.2,6 449.7and 6 408.6kg/hm^2 respectively,which increased by 8.24%,7.87% and 7.18%respectively compared with the contrast Yangmai 158.These three lines should be involved in the regional test in the next year.The principal component analysis and partial correlation analysis indicated that effective panicles contribute more to wheat yield.
