摘要
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 crossability of 30 Landraces of common wheat (Triticum aestivum L.) in the Sichuan Basin with Aegilops tauschii Ccsson and rye (Seaalc cereal eL.) has been studied. The results are as follows: 1. There exists high compatibility genes,kr1 and kr2, in many Landraces which are widely distributed in the Sichuan Basin. 2. The crossablity of wheat with Ae. tauschii and with rye may respe- ctively be controlled by different genetic systems. 3. There are two more pairs of genes in wheat besides kr1 and kr2. One is good for the crossability with rye (kr3) and another (kr4) with Ae. tauschii. 4. Some landraces of Common Wheat have bcen found, Which carry 1、2 or3 pairs of high crossability genes With rye and Ae, tauschii.
