摘　　要：种质资源的多寡、优劣及其研究利用的水平,决定育种的成效。市场经济知识产权时代,使过去无条件种质交流盛况荡然无存。基于此,在与市场经济相适应的种质资源交流及其共享机制形成之前,以现有的资源为基础加速开发扩增,拓宽种质;分析探讨我国育种家利用各种种质素材选育新型优良自交系及杂交种等方面的成功经验,是育种机构育种家加速新品种选育的必然途径。<Abstrcat> The quantity,quality and utilization level are keys to result of breeding.At the age of economic intellectual right,the formal situation of conditionless germplasm exchange exist no longer.Under this situation before the formation of suitable germplasm exchange or share mechanism,the only way out for breeding organization is to expand germplasm through regeneration on present basis and learn successful experience from Chinese pioneer breeders to use all possible material for selection of new type fine self-bred lines or hybrids.
