金早6号雄性不育性的遗传以及在早籼胞质背景的遗传表达

金早6号雄性不育材料杂交后代的遗传观察表明，金早6号雄性不育性属单基因隐性遗传。雄性不育性与褐色颖壳两个性状属独立遗传。用金早6号雄性不育株与可育株杂交F1植株为父本，10个早籼品种为母本，配制10个复交组合。F1代正常可育。F2代10个早籼胞质的组合都分离出雄性不育株。未发现与雄性不育基因互作导致可育的胞质类型。

Heredity of No.6 Jinzao rice male sterile line and its genetic expression based on early indica cytoplasm

The observation on the heredity of No.6 Jinzao rice male sterile line hybrid progeny revealed that the infertility of No.6 Jinzao is genetically controlled by a pair of recessive genes. The two traits of the male sterility and brown paddy hull are inherited independently. Ten multiple crossing combinations were made by using the F 1 plants of No.6 Jinzao sterile plants/ the fertile plants as the male parents and using ten early indica cultivars as the female parents. The F 1 of these combinations are normally fertile while there appeared male sterile plants from each F 2 . No fertile cytoplasmic type caused by the interaction between the genes of cytoplasm and male sterilty was observed.
