产量是作物整个生命周期的最终产品,理想株型设计的首要目标是提高产量潜力.一个作物品种生长在适宜环境条件中,养分和水分的供应不受限制,虫害、病害、草害、倒伏和其他灾害都得到有效控制,在这样的条件下才能充分发挥这个品种的遗传产量潜力.C. M. Donald在1968年就已采用“理想型”这个名称,虽然他认为成功的育种家在选育时,头脑 Yields are the end product of the entire crop’s life cycle and the primary goal of ideal plant-based design is to increase yield potential. There is no restriction on the supply of nutrients and moisture to a crop species grown in suitable environmental conditions. Pest, disease, grass damage, lodging and Other disasters have been effectively controlled under such conditions to give full play to the genetic yield potential of this variety.CM Donald in 1968 has adopted the name of “ideal type”, although he considered successful breeders in breeding ,mind
