樹豆系統間農藝性狀的變異

Abstract

以收集自國內樹豆58系統及國外引進之30系統，合計88系統為材料，調查農藝性狀，結果發現：國外品系之鮮莢色大都屬3-4型；而國內則多屬5-7型，莢型則有曲和直兩型，花色皆為黃花，國內、外品系旗瓣顏色之變異從1-6型皆有。葉型方面，國外品系完全為橢圓形，國內品系全屬長披針型。國內品系主莖顏色之變異從整株全綠、綠帶棕色至全棕色皆有；而國外品系衹有綠及綠帶棕色兩型。開花期一般而盲，國外品系皆比國內品系早開花。種子顏色方面，國內品系大多為淡褐色及黑色；而國外品系多為棕色。國內品系之再生力較國外品系強。產量方面初步可考慮13、14、15、183、184、186、195、197、198、203及206號等11個品系。 Eighty-eight Strains collected from Taiwan (58 Strains), India, Sri Lanka, Nigeria, Australia and ICRISAT. Characters of the plants were observed from the seedling stage to maturity .The results summarized as follow : All 88 Strains had yellow flowers, linear or hooked pod, and the variation of standard color were from 1 to 6 pattern. Foreign introduced strains were variation of fresh pod color from 3 to pattern, main stem color from green to mixed with green and brown. Which had elliptic leaflets and brown seed. Strains of Taiwan were variation of fresh pod color form 5 to 6 pattern, main stem color From green, mixed with green and brown Which had lanceolatic leaflets and drad or dark seed. In general, Strains of foreign were more earlier flowering and less stronger vigor than of Taiwan. For higher seed yields purposes, we may consider to planting No.13, 14, 15, 183, 184, 186, 195, 197, 198, 203 and 206 strains.
