【摘要】 用非洲茄(Solanum gilo RADDI.)作为细胞质供体亲本,茄子(S.me-longena L.)作为轮回回交父本,通过种间杂交及连续三代的置换回交和选择,获得了两个茄子异质雄性不育系。其中9334A为花药瓣化型雄性不育,2518A为花药退化型雄性不育。两者的雄性不育性表现稳定,不育率及不育度均达到100％,而雌性育性正常。用22个茄子地方品种分别与两个不育系进行测交试验,结果表明,其雄性不育性属胞质型遗传。更多还原

【Abstract】 Two cytoplasmic male sterile lines of egg-plant were developed by backcrossing thrice the F1 hybrids of an interspecific cross between the African egg-plant( Solanum gilo Raddi ) and the Chinese egg-plant (S. melongena L. ) by using the African egg-plant as the cytoplasm-donor pa-rent and the Chinese egg-plant as the recurrent paternal parent. One of the two male sterile line ( 9334A ) is a petaloid one, the anthers of which have transformed to narrow incurved petals, and the another one ( 2518 A)is a vestigial anther sterile type, the anthers of which do not produ-ce any pollen. Male sterility of both lines is stable under the climatic conditions of Guangzhou area, unaffected by temperature. In a series of test-crossing of these two male sterile lines with 22 common cultivars of S. melongena, it has been found that not a single male fertile plant would appear in the progenies. This suggests that 9334A and 2518A are two cytoplasmically inherited male sterile lines.更多还原
