| 摘 要： | 研究了食用向日葵杂交种的12个性状与产量的相关关系,并进行了通径分析。结果表明:各性状与产量的相关系数大小依次为,单盘粒重株高茎粗单盘结实数百粒重单盘总粒数结实率籽仁率叶数粒宽盘径粒长。产量与盘径呈不显著正相关,与粒宽和粒长呈不显著负相关,与另9个性状呈极显著正相关。株高、百粒重、单盘粒重和单盘结实数对产量的直接作用效应较高。

| Abstract: | Path and correlation coefficient analysis of 12 yield components were studied for confectionery sunflower hybrids.The results indicated that the correlation coefficient of each characteristic and yield was yield per plant〉plant height〉stem diameter〉seed number per plant〉100-seed weight〉disc flower per head〉percent seed set〉kernel in seed〉leaf number〉seed width〉head diameter〉seed length.The yield and head diameter was non significant positive correlation.The seed width,seed length and yield were non significant negative correlation.The yield and other 9 characteristics were highly significant positive correlation.The results were obvious highly effects of plant height,100-seed weight,yield per plant and seed number per plant on yield by the path coefficient analysis. |
