摘要
试验针对食用向日葵育种中存在的实际问题,对其主要性状进行典型性相关分析研究。结果表明:食用向日葵产量性状与形态性状、生育期之间的相关主要是由产量性状中的单盘粒数、籽实产量和形态性状中的株高、叶片数及生育期的相关引起。以上结果可为食用向日葵杂交育种研究提供依据。
Aiming at resolving the breeding problem of confection sunflower, canonical correlation analysis was used for its main characters in this research. The results showed that the relationship between the yield/morphological characters and growing period was caused by the seed yield/grain number per head and the stem length/leaf number. The above results can be used as scientific evidences for hybridization breeding of confection sunflower.
