Abstract

The quality of vegetable soybean is judged by both morphological and chemical traits. The objectives of the present study were to estimate the 1. genotype-environment (GxE) interactions and 2. the broad-sense heritabilities of graded pod yield, days to harvest, 100-green bean weight, sugar content and pod color value in vegetable soybean. This information will be useful for breeding adapted vegetable soybeans in Taiwan. F6- and F7-derived lines were evaluated in replicated trial in spring, summer and autumn seasons from 1996 to 1999. Lines evaluated in trials differed among years. Results showed that variation in graded pod yield, days to harvest, sugar content and pod color value were mostly due to season and season by genotype (SxG) interactions. However, variation due to genotype accounted for most variation in certain sets of selections and years. Most of the variation in 100 green bean weight was due to genotype. Broad sense-heritability estimates for 100 green bean weight (0.58 to 0.93), days to harvest (0.52 to 0.92) and sugar content (0.24 to 0.86) were fairly high, while heritability estimates for graded pod yield, and pod color values were low. A highly significant negative correlation of-0.50*** between sugar content and oil content was found. This is the first report of such a relationship in vegetable soybean. The correlation between protein content and sugar content was also largely negative but quite variable with seasons and years. Highly significant negative correlation was also found between sugar content and protein plus oil (0.52***). Plant breeder can expect rapid progress from selection for 100 green bean weight and days to harvest. Selection for low oil content would result in higher sugar content. 毛豆外銷日本的規格必須符合毛豆莢外觀及豆仁及品質上的要求。本試驗的目的在決定1）基因型和環境間的交感作用，2）合格莢產量、收穫期、鮮百粒重、糖份及莢色等性狀的廣義遺傳率，以利於毛豆品種選育上的應用。由F6及F7中挑選所得的優良品系，在85至88年間進行兩重覆，每年三季的品交產量比較試驗調查合格莢產量、播種期、毛豆收穫期、鮮百粒重、種仁含糖量及莢色等性狀。結果顯示合格莢產量、含糖量及莢色的總變異量主要來自季節及季節和品系間的交成作用；鮮百粒重的總變異量則來自品系。相對於鮮百粒重，毛豆收穫期及含糖量的高遺傳率估值，合格莢產量和莢色的遺傳率估值則較低。含糖量和油份間有顯著的負相關，而蛋白質和含糖量間的負相關則在不同季節或年度有不同程度的顯著性。所以，在育種上可進行鮮百粒重及收穫期的有效選拔，而進行低油份品系的選拔則可穫得高含糖量的品系。
