摘要

本研究之目的為選育無縫絲豆莢性狀及具抗銹病之菜豆品種，以減少藥劑防治次數，提高本省菜豆品質。於1990年進行無縫絲豆莢與抗銹病親本之篩選。1991年春作行雜交，以抗銹病栽培品種台中一號為雌親，抗銹病國外品種Fortex為雄親。經進行後裔分離選拔及品系試驗。初步結果顯示新參試品系之抗銹病性反應皆介於極抗至中抗之間，各品系都具低結莢節位、豆莢具無縫絲、口感良好，其中以83-10及83-11兩品系產量最高，比對照品種台中一號增產30%，比灰仁增產23%，將可作進一步試驗之材料。

The objective of this study is to breed both of rust-resistant and stringless varieties for improving bean production in Taiwan. The experiment was initiated in 1990 of screening lines possessing both rust-resistant and stringless lines as parent. Hybridization between Taichung#1 (female parent) and Fortex (male parent) was made in the fall of 1991. The progenies were subjected for line selection and yield trials. The results showed that the lines, 83-10 and 83-11 are highly rust-resistant and stringless in pod. As well as high yield, long pod and low first-podded node.
