不同生态类型区小麦种质资源经济性状的相关性研究

本文对30份来自不同生态类型区小麦种质资源经济性状的相关性研究分析，结果表明：小麦种质资源各经济性状之间存在着不同程度的相关：单株有效穗数与株高、穗长、不孕小穗数、穗粒重、千粒重负相关不显著；与穗下节长呈显著正相关；与单株产量呈极显著正相关。株高与可孕小穗数、穗粒数、穗粒重负相关不显著；与穗下节长、颈长、穗长、不孕小穗数、千粒重、单株产量呈正相关。穗下节长与不孕小穗数呈极显著负相关；与单株产量呈显著正相关；与颈长呈极显著正相关。颈长与千粒重呈显著负相关。穗长与可孕小穗数、千粒重呈显著正相关；与穗粒数、穗粒重呈极显著正相关。可孕小穗数与穗粒数、穗粒重、单株产量呈极显著正相关。不孕小穗数与穗粒重呈显著负相关；与穗粒数呈极显著负相关。穗粒数与穗粒重、单株产量呈极显著正相关。穗粒重与千粒重、单株产量呈极显著正相关。千粒重与单株产量呈显著正相关。

Study on Relativity of Wheat Germplasm Resources Economic Character in Different Zones of Ecological Types

Through the different types of ecological zones of wheat germplasm resources related to the economic character of research and analysis,the results showed that: different types of ecological zones of wheat germplasm resources between the various economic characters there are different degrees of correlation.The effective ears per plant and plant height,ear length,infertility small ears,heavy grain,grain weight no significant negative correlation with the long section under the Sui was positively correlated with the yield per plant was a significant positive correlation.Height may be pregnant with small ears,the number of grain,grain burden related significantly with the Fringe Festival under the long,long neck,ear length,infertility small ears,1 000-grain weight and yield positive correlation.Fringe Festival under the long ears and small infertility was a significant negative correlation with the yield was positively correlated with the long neck was a significant positive correlation.Neck-and 1 000-grain weight was negatively correlated.Ear length may be pregnant with small ears,1 000-grain weight was significantly correlated with the number of grain,grain weight was a significant positive correlation.Small ears and pregnancy can spike the number of grain weight,yield a significant positive correlation.Infertility small ears and grain weight was negatively correlated with the number of grain was a significant negative correlation.Grain and grain several heavy,yield a significant positive correlation.Ear weight and grain weight and yield a significant positive correlation.1000-grain weight and yield was positively correlated.
