| 摘 要： | 运用相关分析对20个向日葵杂交种的9个主要性状相互关系进行研究,结果表明:与产量显著相关的性状是单株粒重、叶片数和株高,它们与产量的相关系数分别为0.999 8、0.670 3和0.602 7;与含油率显著相关的性状为出仁率,其相关系数是0.717 2。因此初步认为向日葵产量育种应把重点放在增加单株粒重上,并选择高大的多叶片类型,而在高油的品质育种上提高出仁率应成为重要的育种指标。

| Abstract: | Study on 9 main characters of 20 sunflower hybrids was conducted with correlation analysis.The results indicated that the characters significantly relative to seed yield was grain weiqht of plant,number of leaf,plant height.The coefficients of correlation were 0.999 8,0.670 3 and 0.602 7 respectively.The remarkable positive correlation was percertage of kernel,whose coefficient of correlation was 0.717 2.So the grain weight of plant should be put in the first place of sunflower breeding.The tall type of many leaves of plant should be chosen.The percentage of Kernel in the quality breeding should become the important breeding target. |
