【摘要】 以3个二角型1B/1R小麦不育系ms(bicor)-83(37)65,ms(bicor)-偃师9号,ms(bicor)-80(6)和1个非1B/1R不育系ms(bicor)-90-110与不同基因型小麦非整倍体系列(单体、缺四体和重双端体)及8个不同的恢复系杂交,调查不育系本身和杂种F1产生单倍体的频率及其杂种F1代的育性恢复性。结果表明,二角型1BL/1RS不育系杂种F1代产生单倍体的频率与不育系自身1B/1R易位染色体组成有很大关系,亦与父本的染色体构成有关,父本的非整倍体系列有提高单倍体频率的趋势,而与杂种F1的育性没有直接关系;二角型非1BL/1RS不育系自身及其杂种F1代无单倍体产生。更多还原

【Abstract】 The four male sterile lines of wheat with Ae.bicornis cytoplasm,among them ms（bicor）-83（37）65,ms（bicor）-Yanshi No 9 and ms（bicor）-80（6）are 1B/1R genotype and ms（bicor）-90-110 is non-1B/1R genotype,were tested crossing with the aneuploid with different construction of chromosome,namely 1B monosomic,1B double ditelosomic (20Ⅱ+tt^1BS+tt^1BL) and nullitetrasomic （1B⁰1D^Ⅳ）,and eight wheat varieties or lines and partial parent materials.Its haploid frequency of Male Sterile Lines and F₁,and the fertility restoration performance of F₁ were investigated.The results are as followings:① the frequency of the F₁ hybrid of the male sterile lines of 1B/1R wheat with Ae.bicornis cytoplasm was related to the constitution difference of 1B/1R translocation chromosome of male sterile lines;② it was also related to the construction of chromosome of male parent,and the aneuploid can increase the trendy of the frequency of haploid;③ there was no relation between the frequency of haploid and fertility;④ there is no haploid plant in the male sterile line of non-1B/1R wheat and its F₁.更多还原
