摘要
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。
Wheat super-high-yield is the main breeding goal in the period ＂the tenth five＂. The key of increasing wheat yield per unit area is breeding super-high-yield variety. The article studies the main indexes of wheat super-high-yield breeding. The ideal model of super-high-yield should be based on certain sum of spike,accentuate on improving sum of grain per spike and mainly gain grain weight of per spike.
