【摘要】 普通烟草（Ｎ．ｔａｂａｃｕｍ）与野生粉蓝烟草（Ｎ．ｇｌａｕｃａ）叶肉原生质体诱导融合获得体细胞杂种，其中编号为ＴＧ－８的植株除具有雄性不育特征外，其他生物学性状及体细胞染色体数目均与其普通烟草亲本相同，且遗传性状稳定，表现为典型的胞质杂种特征。用普通烟草做轮回亲本与其杂交至１２代，后代仍然保持雄性不育特征。用烤烟品种Ｇ－２８回交４代，选育出烟草新胞质雄性不育系８６－６。用８６－６与烤烟新品系８８－４及８６－１组配成一代杂交种９２－７、９２－８，杂种优势明显，抗病性也有提高。更多还原

【Abstract】 A interspecific hybrid was produced by protoplast fusion between N. tabacum(2n=48) and N.glauca (2n=24). The hybrid, designated as TG\|8, resambled N. tabacumfor most of the morphological characters except male sterility. The male sterility keeps no segregations in the back\|cross progonies for 12 generations. A new tobacco cytoplasmic male sterile (CMS) line named 86\|6 was obtained after TG\|8 backed crossed with G\|28 for four generations. The F1 hybrids named 92\|7928,obtained by crossing 866 with 884 and 861 separately, were also tested for yield, quality and disease\|resistance.\=更多还原
