【摘要】 以紫花西安绿茄及其自然突变产生的白花株系和原亲本为试材,研究了茄子花色遗传特性,分析了花色突变对植株、花朵、果实等相关性状的影响。结果表明,茄子的紫花与白花由一对基因控制,紫花“Col”对白花“col”完全显性。与紫花株系相比,白花株系生长旺盛,单花雄蕊数多,花粉粒大,花粉量少,果内种子数少,果实大,产量高,可直接做栽培品种利用。白花性状可用作茄子品种和杂交种纯度鉴定的标记性状。更多还原

【Abstract】 The inheritance of the white-flower and its influence to related characters in eggplant were studied with the white-flowered mutant of XIANLVQIE and its maternal bred.Result showed that the flower color was attributed to a couple of complete dominance genes.Purple color flower "Col" was dominant to the white "col".Compared with the purple-flowered strain,the white-flowered strain not only grew more blooming,but also had more stamens in one flower,less pollens in one anther and less seeds in one fruit.In the meanwhile,in white-flowered eggplants,microspore and fruit was bigger,and yield was higher than purple-flowered.The white-flowered strain could be used as a variety and the white-flowered character could be used as a marker to appraise purity of hybrid in eggplant.更多还原
