摘　　要：利用生态育种的观点通过分析赤峰地区审定且大面积推广种植的高粱杂交种及其亲本系谱,从中找出对选育适应本生态区域种植的新品种有益的东西。亲缘关系越远,杂种优势越明显。以此科学的制定育种目标,选择理想的种质材料、熟期范围、杂优利用模式,为群体改良选择亲本时提供一定依据,增加育种的预见性,提高成功率。The author analyzed the sorghum hybrids and parents pedigree which have been passed the examination and approval and have been popularized planting in large area of The ChiFeng Region based on theoretical ecological breeding.From the analyzed result,We found the useful things for breeding new variety which adapt to the ecological areas that the higher Heterosis comes from the far Genetic Relationship.Using the result,we can making scientific breeding objectives,choosing ideal germplasm resources,mature period,utilization model of heterosis and the better parent selection,increasing the foreseeability, improving success rate.
