(1)对西北农大提供的六个K、V型小麦不育系进行自交和测交鉴定的结果:K80(6)A、K陕7859A、K83(37)65A和K(D_1/9615)A的不育性不稳定;K-149A育性有轻度分离;V-77(2)A不育性稳定。(2)对K、V、T型不育系雄性器官观察比较,V型不育系花粉败育比之K型完全,近似于T型不育系。(3)分析测交父本的血缘,具有1B/1R血缘的小麦品种(系)绝大多数为K、V型的保持系,非1B/1R血缘的绝大多数为其恢复系,但恢复度普遍偏低。(4)V型不育系及其测交杂种产生单倍体的频率高于K型。 (1) The results of selfing and cross test of six K, V type male sterile lines provided by Northwest Agricultural University: K80 (6) A, K Shaanxi 7859A, K83 (37) 65A and K (D_1 / 9615) A sterility instability; K-149A fertility with mild separation; V-77 (2) A sterile stability. (2) Comparison of K, V, T male sterile organs showed that pollen abortion of V type sterile line was completely similar to K type, which was similar to T type sterile line. (3) Analysis of the bloodline of male parent of test-crossing, most of the wheat cultivars (lines) with 1B / 1R bloodline are maintainer lines of K and V type, while the majority of non-1B / 1R blood lineage is their restorer line, The degree is generally low. (4) The haplotype frequency of V type CMS and its cross hybrids was higher than that of K type.
