经多年多次试验结果证明:克字号小麦与黑麦杂交,结实率较高,并首次筛选出春性、综合性状好的桥梁品种,克服了远缘杂交不亲合性。这说明克字号小麦具有黑麦血缘,遗传基础广泛;新桥梁品种比外引冬性桥梁品种农艺性状好,适于当地应用;综合性状好的桥梁品种与黑麦杂交创造的异源八倍体小黑麦综合性状也好,同时,因桥梁品种特性的遗传信息不同,创造出的异源八倍体小黑麦也完全不同;不同桥梁品种与同一黑麦杂交其结实率不同,同一桥梁品种与不同黑麦杂交结实率也不同。据此可认为,杂交结实率高低与双亲遗传基础均有关系;桥梁品种的好坏,直接影响异源八倍体小黑麦的饱满度和结实率。这说明和桥梁品种遗传因素的影响有关;与黑麦杂交不结实的小麦,先与桥梁品种杂交再与黑麦测交,大部分就能结实,这说明可孕物质具有可转移性。
After many years of test results show that: K-type hybrid wheat and rye, the higher seed setting rate, and for the first time screening of spring, comprehensive traits bridge species to overcome the incompatibility of distant hybridization. This shows that the gram-type wheat has the rye blood margin and has a wide range of genetic basis. The new bridge varieties are more agronomic traits than the bridge species of the north-facing bridge and are suitable for local applications. The heterotrophic octoploids Triticale has the same comprehensive traits, at the same time, because of the different genetic information of the characteristics of the bridge breeds, the heterologous octoploid tritreeae are also completely different. The crosses between different bridge breeds and the same rye are different in seed setting rate, Different rye hybrid seed set rate is also different. Therefore, it can be considered that the seed setting rate of hybrids is related to the parents’ genetic basis. The quality of bridge varieties directly affects the plumpness and seed setting rate of heterologous octapeptide triticale. This shows that the genetic factors and the impact of the bridge varieties; and rye poor hybrid wheat, first with the bridge varieties and then cross with the rye, most will be able to fruition, which shows that fertile material is transferable.
