选用9个小麦新品系组成不同的混系群体,比较了混系群体与纯系群体的产量表现。结果表明,小麦混系群体与纯系群体相比在产量方面并没有绝对优势,但在一定条件下也可能出现产量超过相关纯系最高产量的组合类型;混系群体的产量表现与组成该群体的纯系的平均产量具有一定的正相关性,纯系的产量水平可以作为小麦混系品种组配的产量依据。
Nine new lines of wheat were selected to form different mixed lines, and the yield performance of mixed lines and pure lines was compared. The results showed that there was no absolute superiority in the yield of the wheat mixed population compared with that of the purebred group, but under certain conditions, the combination type with the yield exceeding the highest yield of related pure lines may also appear. The yield performance of the mixed group and the composition of the group The average yield of pure lines had a certain positive correlation. The yield of pure lines could be used as the basis for the production of mixed wheat lines.
