Identification and Evaluation of Application Value of Wheat Germplasm Resources in Breeding
摘要
Abstract
[ Objective ] The aim was to identify and evaluate the application value of wheat germplasm resources in breeding. [ Method ] Some agronomic characters of 260 wheat breeding materials like winter and spring trait, cold resistance and disease resistance were observed, furthermore some agronomic characters were identified by indoor molecular marker detection. [ Result] The winter and spring trait of wheat was controlled by vernalization gene, which decided the planting area of wheat. Cold resistance and growth period of wheat were closely related to the winter and spring trait. Results of indoor molecular marker detection was basically identical with the resistance performance in field. Correlation analysis on disease indexes of various diseases like powdery mildew resistance, sheath blight and leaf rust disease showed that there was no significant correlation among the diseases, Yield structure and yield level of present breeding varieties were understood by analyzing yield structure and comprehensive agronomic characters of some approved varieties. [ Conclusion] The research provides theoretical basis for studies on wheat breeding.关键词
