事物之间的相互联系是事物发展的必然规律.同一作物的个体和群体间,同一个体的不同器官间,或单一器官和整体之间,都构成一定的相互关系.在作物的个体发育过程中,不同器官或不同性状之间的相互联系称为性状之间的相关(Correlation).这种相关有正和负的关系,相关系数在+1和-1之间.关于棉花的经济性状之间或经济性状和形态性状之间的相关问题,已有许多人进行过研究.Griffee等(1929)报导,籽棉产量和叶枝数的相关系数为-0.46±0.12,籽棉产量与
The interrelationship between things is the inevitable law of the development of things.The same crop individuals and groups, between the same organ of different organs, or between a single organ and the whole constitute a certain relationship between the individual development of crops in the process , The relationship between different organs or different traits is called Correlation. This correlation has a positive and negative relationship with a correlation coefficient between +1 and -1. As for the economic traits or economic Many researchers have studied the correlation between traits and morphological traits.Griffee et al. (1929) reported that the correlation coefficient between seed cotton yield and leaf number was -0.46 ± 0.12,
