Description

An inheritance study on the three phenotypes of glossiness, including glossy (g), non-glossy (G) and true-glossy (tg), was conducted using seven varieties (3 true-glossy, 3 glossy, 1 non-glossy), and 23 F1 and F2 between the above varieties with different phenotypes. The phenotypes of F1 were g in the combination of (tg×g), G in (tg×G) and G in (g×G), respectively. In the F2 of (tg×g), (tg×G) and (g×G) where segregations were observed in glossiness, the expected ratios of (tg: g=3: 1), (tg: G=3: 1) and (g: G=3: 1) were well fitted. These results suggest that tg, g and G would be multiple alleles located in a glossy locus. Although the symbols gl and Gl were proposed for g and G by Tarumoto (1980), the symbols gl1, gl2 and gl+ are newly proposed to denote the multiple alleles for g, tg and G in the glossy locus, respectively.
