Phenotypic diversity of sugarcane variety germplasm
甘蔗品种资源的表型遗传多样性

Sugarcane varieties are important in providing parental resources in sugarcane breeding programs.In order to improve efficiency in selecting sugarcane varieties as parents,to provide guidance in choosing the best parent combinations for crossing,and to assist in choosing core collections of parents,the genetic variation,genetic structure and relationships of a range of traits were studied in a set of sugarcane varieties from different origins.Seventeen qualitative traits and five quantitative traits were st...
