摘　　要：黄绿苗浙１２－１２Ｎ突变体与其它芽黄突变体的基因等位性测验结果表明，浙黄绿苗基因与已鉴定的ｖ１、ｖ２、ｖ３、ｖ４、ｖ５ｖ６、ｖ８、ｖ９、ｖ１０、ｖ１１、ｖ１２、ｖ１４、ｖ１５、ｖ１６ｖ１７、ｖ１８、ｖ１９、ｖ２０等芽黄基因属非等位性。遗传研究结果表明，黄绿苗突变体浙１２－１２Ｎ的黄绿苗性状受一对隐性基因控制，与ｃｕ（杯状叶）、Ｌ°（鸡脚叶）、ｃｒ（皱缩叶）、ｆｇ（窄卷苞叶）、ｃｌ１（簇生铃）、ｇｌ１（无腺体－１）、ｎｅ１ｎｅ２（无蜜腺）等隐性基因均表现为独立遗传，该基因符号暂定为ｙｇｚ。By allelism test, it was found that a new yellow-green seedling mutant, Zhe 12-12N, is not allelic to virescent genes including ν1,ν2,ν3,ν4,ν5ν6,ν8,ν9,ν10,ν11,ν12,ν14,ν15,ν16ν17,ν18,ν19, and ν20. This mutant is controlled by a pair of recessive genes which is independent of recessive genes cu (cup leaf), L°(okra leaf), cr (curly leaf), fg (frego bract), cl1 (cluster boll 1), gl1 (glandless 1), ne1ne2 (nectarilessness). We tentatively name this new gene as ygz.
