灰色评价杂交组合,提高小麦育种效率

Gray evaluating hybrided combinations and raising efficiency of wheat breeding

利用灰色系统理论和方法 ,根据 9个性状对 1 1个冬小麦 F1 杂交组合进行了综合评价 ,定量地评定出综合性状较好的杂交组合预以保留 ,较差的组合预以淘汰 ,这样可减少 F2 及以后各代的工作量 ,克服了育种工作的盲目性 。

Using the theory and method of gray system,synthetical evaluation was made on 11 winter wheats F 1 hybrided combinations according to 9 characters.Quite good combinations evaluated quantitatively were reserved,quite poor combinations were eliminated.So the working amount of F 2 and its later generations was reduced.The blindness on breeding was overcome. The working efficiency on wheat breeding was improved.
