Comprehensive Evaluation of the Major Agronomic Traits and Cluster Analysis of Cotton Germplasm Resources
摘要
Abstract
[ Objective] To conduct comprehensive evaluation on the main agronomic traits for 153 land cotton germplasm resources to reveal characteristics and genetic relationship among cotton germplasm resources and provide parents for cotton breeding. [Method]Investigation of the nine yield traits, five quality traits and twelve phenotypic traits of various materials were conducted . Data analysis and organizing applied SPSS13.0 and DPS. [ Result] The variation coefficient is big for yield traits , and small for quality traits. Correlation analysis indicates that significant positive correlation exists between fiber length and strength, strength and elongation. And significant negative correlation exists between fiber length and fineness, strength and fineness. Clustering analysis result reveals two large categories and three small categories. 33 specific germplasm resources are screened . [ Conclusion ] This group of cotton germplasm materials can provide rich parents materials for cotton breeding and genetics studies.关键词
