摘要

本研究之目的為選育具抗銹病之扁莢菜豆品種，以減少病害防治成本，增進菜豆品質，提供菜豆栽培者優良品種。試驗於1992年由美國農部引進15個抗銹病菜豆品種，次年進行觀察試驗時，發現其中PI 1924-s-5之園藝性狀尚在分離，經選拔及進行品系試驗並於不同地區栽培，結果顯示RR-83-09，RR-83-11，RR-83-12等三個新品系之抗銹病性反應皆為極抗。而其嫩莢長度、厚度、單莢重，皆優於對照品種，並具特殊口感。春作產量比對照品種屏東大莢各增產63.7%、74.9%，值得繼續進一步試驗，以選拔優良品種，俾供推廣栽培。

The purpose of this study was to select rust-resistant varieties of flat-pod common bean. In order to prevent the disease and to decrease the cost of plant protection and to promote the quality of common bean, fifteen rust-resistant varieties were introduced from USDA in 1992 for trial in the field. The lines of PI 1924-s-5 ware segregated and selected for comparison of hoticultural characteristics. The results of the trial in the different locations showed that the two lines RR-83-09 and RR-83-11 were very resistant to rust disease. In addition, pod length and pod height were better than that of the control variety. The yields of spring crop of these two lines were 63.7% and 74.9% higher than that of the contral variety, respectively.
