新材料“J-11”比众所周知的高亲和性品系“中国春”具有明显更高的与黑麦的可杂交性。遗传分析表明,“J-11”与“中国春”的可杂交性基因一样表现为完全隐性。但控制“J-11”和“中国春”与黑麦可杂交性的基因型确实不尽相同。“J-11”除具有“中国春”的3对可杂交性基因,即5B上的kr_1、5A上的kr_(?)和5D上的kr_3外,还具有1个新的可杂交性基因kr_4,位子1A染色体上。新基因kr_4表现为强效,其效应比kr_1的弱,但比kr_2和kr_3的强。小麦可杂交性基因间存在互作,表现为纯合隐性等位基因对其它显性等位基因的抑制作用,而纯合隐性等位基因间的效应具有可加性。
The new material “J-11” has significantly higher hybridisability to rye than the well-known high-affinity line “Chinese Spring”. Genetic analysis showed that the “J-11” and “Chinese Spring” hybrid genes can be as completely hidden. However, the genotypes that control the hybridization of “J-11” and “Chinese Spring” with rye are indeed different. “J-11” has one new hybridizable gene, kr_4, in addition to three pairs of hybridizable genes with “Chinese Spring”, that is, kr_1 on 5B, kr_ (?) On 5A and kr_3 on 5D , Seat 1A chromosome. The new gene kr_4 showed potent effect with weaker effect than kr_1 but stronger than kr_2 and kr_3. There are interactions between hybridizable genes in wheat, which show the inhibitory effect of homozygous recessive alleles on other dominant alleles, while the effect of homozygous recessive alleles is additive.
