当前在农业生产上,已广泛利用杂种优势来提高作物单位面积产量。但杂种优势的强弱,因性状而异;同一性状又因不同的组合而不同。探讨西瓜品种间杂交一代主要性状的表现规律,对杂交组合的亲本选配和利用,都具有重要的实践意义。自1979年以来,我们结合西瓜常规育种工作,进行了观察与分析。
Currently, in agricultural production, heterosis has been widely used to increase yield per unit area of crops. However, the strength and weakness of heterosis vary with the trait; the same trait varies with different combinations. It is of great practical significance to explore the performance of the main characters of the cross between the watermelon cultivars and to select and utilize the parents of the cross combinations. Since 1979, we combined routine watermelon breeding, conducted observations and analysis.
