在作物育种工作中,鑑定和分析作物产量性状的形态特征及其相关变异,是掌握育种材料、提高选择效果的重要环节。根据棉花产量性状的分析,决定棉株生产率的主要因素是:单株结铃数和棉铃有关的各项经济性状。棉铃是以花器为发育基础的,推论其性状之间可能具有一定的关联。因此,鑑定和分析棉花的花器和棉铃各项形态指标及其相互关系,对于棉花育种工作的开展具有一定的意义。关于棉花种间和品种间以及杂交种与其亲本间各项经济性状的鑑定及其相关性的测定,国内外已有很多研究。但对棉花花器构造与棉铃及籽棉性状的鑑定
In the field of crop breeding, the identification and analysis of morphological traits and their related variations of crop yield traits are important links to master breeding materials and improve selection effects. According to the analysis of cotton yield traits, the main factors that determine cotton plant productivity are: the number of bolls per plant and the economic traits related to bollworm. Cotton boll is based on the development of flowers, inferred that the traits may have some correlation between. Therefore, identification and analysis of cotton flower and cotton boll morphological indicators and their relationship, for the cotton breeding work has a certain significance. There are many studies both at home and abroad on the identification of the economic traits and the determination of the correlation between the cotton species and the varieties and the hybrids and their parents. However, the cotton flower structure and identification of cotton boll and seed cotton traits
