超高产小麦育种是“十五“期间的主要育种目标。选育超高产品种是提高小麦单产的关键。本文就小麦超高产育种的主要指标进行探讨 ,超高产育种的主要模式应建立在一定穗数的基础上 ,着重提高每穗粒数和千粒重 ,主攻穗粒重。
Super-high-yielding wheat breeding is the main breeding target during the 10th Five-year Plan. Breeding super high-yielding varieties is the key to raising wheat yield. In this paper, the main indicators of super-high-yielding wheat breeding are discussed. The main patterns of super-high-yield breeding should be based on a certain number of spikes, focusing on raising the number of grains per panicle and 1000-grain weight, and mainly focusing on the grain weight per spike.
