摘要
通过分析P群种质选育的品种,结合育种实践,认为P群种质是不同于我国原有4大杂种优势类群的一个相对独立的新的优势群。总结出P群种质的主要杂种优势模式,即P群×Reid类群、P群×塘四平头类群、P群×旅大红骨类群和P群×其它种质类群。提出了P群种质在今后玉米育种和种质扩增中存在的问题和利用思路。
An analysis of the maize hybrids,one of parents from P group,in combination with the breeding ex-perience showed P group,as a relatively new group,differs from China's four core groups.The main heterosis pattern of P group was summarized,that was P×Reid,P×Tangsipingtou,P×Ludahonggu and P×others.Problems and new ways of P group utility in maize breeding and germplasm developing were discussed.
