摘要
以4×4不完全双列杂交法研究了茄子遗传距离与杂种8个性状及杂种优势的关系,结果表明:遗传距离与杂种优势、杂种性状间的关系较复杂,直线相关、曲线相关和不相关3种关系都存在,因此在现阶段,完全用遗传距离代替传统方法对亲本进行选择选配还是不太现实的。
The relations between genetic distance and character values/heteroses for 8 traits in eggplant were studied by arranging 44 incomplete diallel cross with a random block design and three replications. The results indicated: the relations between genetic distance and heterosis/hybrid value are complex. There are three kinds of relationships namely linear, curvilinear and noncorrelation. It isnt realistic for us to select and pair parents by using genetic distance instead of traditional methods wholely at present.\;
