| 摘 要： | 选用 6个 T型不育系及其相应的保持系与 5个恢复系配制了 30个 T质杂种和 30个相应的 A质杂种、选用 4个 K型不育系及其保持系与 2个 K型恢复系配制了 8个 K质杂种和 8个相应的 A质杂种、选用 6个普通品种配制了 5个化杀组合 ,以研究杂种小麦籽粒的蛋白质含量和面团流变特性在 F1和 F2 中的表现。结果表明 :1胞质杂种 F1和 F2 籽粒蛋白含量均呈近正态分布 ;78%的组合 F1籽粒以超高亲为主 ,12 %的组合表现倾高亲 ;F2 籽粒以超高亲和偏高亲为主 ,约有 2 5%的组合表现近中亲。普通品种间的化杀杂种 F1籽粒以偏高亲和超高亲为主 ,F2 籽粒以近中亲和偏高亲为主。 2 T质杂种和相应 A质杂种的蛋白含量在 F1代差异不显著 ,但在 F2 代 T型胞质可显著提高籽粒蛋白含量 ;K型胞质可显著提高杂种籽粒 F1和 F2 的蛋白质含量。 3T型胞质可提高杂种小麦的面团流变特性 ;K型胞质使面团流变特性变劣。普通品种间的化杀杂种 F1和 F2 的面团流变特性都介于双亲之间 ,某些组合如早优 50 4×核生 2号组合的 F2 杂种表现倾高亲早优 50 4。

| Abstract: | Seventy six CMS (cytoplasm male sterile) hybrids were obtained from six T-type sterile lines and four K-type sterile lines, and five hybrids from six common wheat cultivars, with the objectives to understand the expression of grain protein contents and dough rheological characters of hybrid wheats in F1 and F2 generations. The results showed that: ①Grain protein contents of CMS hybrids in F1 and F2 were very close to normal distribution. Contents of hybrids of 78% crosses exceeded their high parents, while 12% crosses hybrids were close to their high parents. F1 of CHA hybrids have contents near or above their high parents, and F2 have contents close to their high parents or close to their parents average value in F2. ②No difference of protein content was observed between T-type cytoplasm and its respective A-type cytoplasm hybrids in F1 generation, but in F2 T-type cytoplasm manifested themselves being more higher protein content. K-type cytoplasm could remarkably improve the protein content both in F1 and in F2. ③T-type cytoplasm could improve the dough rheological characters of hybrid wheat, on the contrary, K-type reduce those characters. Dough rheological value of CHA hybrid wheat were in between of their parents; the characters of hybrids of Zaoyou504×Hesheng2 in F2 approached to their higher-contented parent-Zaoyou504. |
