Characteristic Evaluation and Screening of Excellent Kidney Bean Germplasm Resource

Objective] The research aimed to screen out the excellent kidney bean germplasm resource. Method] The biological and botanical characteristics of 445 materials of kidney bean were investigated and the materials that had prominent characteristics and utilization values were evaluated and analyzed. Result] There were 162 shares of dwarfing varieties and 262 shares of sprawling varieties; 185 shares with round stick shape and 60 shares with slightly curved strip-shape; 218 shares with green pods and 150 shares with light green pods; 218 shares with few fiber and 115 shares with medium fiber; 165 materials with kidney shape and 129 materials with elliptic shape; 183 shares with superior quality and 183 shares with medium quality; 202 materials with premature and middle-early mature and 125 materials with late mature and middle-late mature; 267 varieties with strong disease-resistance, 133 varieties with strong insect-resistance, 82 varieties with strong drought-resistance, 84 varieties with strong cold-resistance and 83 varieties with strong heat-resistance. Kidney bean had abundant minerals such as protein, VC, VE, Ca, Fe and Zn with higher relative nutrition value (RNV).The RNV of Vc and Ca in Hongdoukuan were 45.27 and 12.93 resp. Conclusion] 38 varieties such as Hongdoukuan had better comprehensive characteristics, good quality, strong adaptability and higher nutrition value. So they had better popularization value and were better development varieties.
