| 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，曲线相关不相关３种关系都存在，因此在现阶段，安全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。

| Abstract: | The relations between genetic distance and character values/heteroses for 8 traits in eggplant were studied by arranging 4×4 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 non-correlation.It isn''t realistic forus to select and pair parents by using genetic distance instead of traditional methods wholely at present. |
