对三十个四川小麦地方品种与节节麦和黑麦的可杂交性进行了观察、研究,结果表明: “中国春”所含有的高亲和性基因kr_1、kr_2在四川地方品种中普遍存在;小麦—节节麦和小麦—黑麦可杂交性受不同的遗传系统控制;除kr_1、kr_2外,普通小麦中至少还存在两对基因,一对基因(kr_3)对小麦—黑麦可杂交性起作用,另一对基因(kr_4)对小麦—节节麦可杂交性起作用。四川地方品种中,存在有与黑麦和(或)节节麦亲和性很高的品种(系)。
The results showed that the high-affinity genes kr_1 and kr_2 contained in “Spring of China” were widespread in Sichuan local cultivars ; Wheat-rye and wheat-rye can be controlled by different genetic systems; there are at least two pairs of genes in common wheat except kr_1 and kr_2, and a pair of genes (kr_3) can be crossed with wheat-rye Sexual function, another pair of genes (kr_4) on wheat - nodal wheat hybrid sex play a role. Among Sichuan local cultivars, there are varieties (lines) with high affinity with rye and / or Rna.
