Abstract
R基因座控製大豆種皮顏色，在適當基因型之配合下其三個對偶基因的外表型及顯隱性關係為R (黑色種皮) >r-m (黑色條狀棕色種皮) > r (棕色種皮)。本試採用三個具有不同 R 突變對偶基因 (R*，r-m55，r*) 之穩定近同源系 RM30 (R*/R*) ，RM55 (r-m55/r-m55) 及 RM38 (r*/r*) 進行正反雜交，調查 F1、F2 及 F3 植株種皮顏色之變化以探討三個突變對偶基因之遺傳特性及顯隱性關係。
The pigmentation of the seed coats in soybean is controlled by the R locus. Three alleles R, r-m, and r produce black, striped, and brown seed coats, respectively, and show the dominance relationship as R> r-m>r. Two revertant alleles, R* and r* were derived from the r-m55 allele and were all originated from the Clark near isogenic line L72-2040 (i/i, r-m/r-m).
