在小麦高产品种选育中,株高和产量性状是选育的主要目标.近年来,对于株高性状的选育引起了普遍重视,不少育种单位选用矮秆亲本与丰产品种杂交,培育高产矮秆、抗倒伏的品种.但在矮秆选育中,常会出现矮秆与青干、抗病、丰产、早熟等的矛盾;产量性状之间也往往存在着互相联系
In the breeding of high-yielding varieties of wheat, plant height and yield traits are the main targets of breeding.In recent years, the breeding of plant-height traits has aroused universal attention, and many breeding units choose to crossbred dwarf parents and high-yielding cultivars High yield dwarf, lodging resistant varieties.However, in the dwarf breeding, often appear dwarf and dry, disease resistance, high yield, precocity and other contradictions; yield traits also often exist interrelated
