【摘要】 <正> 根据[3],我们采用完全双列杂交法对冬小麦杂种一代进行配合力分析,估算亲本和F₁代的主要农艺性状的一般与特殊配合力效应。为冬小麦杂交育种在正确选配亲本、尽早鉴定出组合优劣以及对杂种后代进行有效选择等方面提供理论参考。更多还原

【Abstract】 A study of general and specific combining abilities of 6 winter whent va- rieties （lines） was made in 6×6 complece diallel crosses. The following cha- racters were studied:heading date, plant height, length of the main spike, pedicle length of the main spike, number of grains of main spike, spikes per plant, 100-kernel weight and grain yield per plant. The general combining abilities of the parents and the specific combi- ning ones of their F₁ hybrid combirations were evaluated. The problems on the selection of parents and their F₁ hybrid combina- tions were discussed.更多还原
