| Abstract: | The main biological traits,young-ear developing characteristics,ear-forming mechanism,source-sink-transportation relationships,as well as the regulating and controlling effects of cultivation measures for heavy-ear winter wheat cultivars are summarized in the paper.Furthermore,some theoretical problems which need to be dealt with for heavy-ear wheat cultivars are explored.The direction of trait improvement and breeding,and the high-yield and high-efficiency cultivation ways for heavy-ear winter wheat cultivars are also clarified. |
