摘　　要：讨论了生态育种的概念，并就生态育种在绵农2号及其姊妹品种选育中的应用进行了阐述。结果表明：①四川气候生态条件有利于小麦幼穗分化发育，能选育出小穗、粒数多的品种生态型；②同组合的亲本、低代和中高代材料在不同土壤生态条件下，可选育出适应范围广的品种及其品种类群；③在易发病条件下才可能选育出高抗病品种。The concept of ecological breeding is discussed, and the practice of ecological breeding in selecting wheat cultivars 'Miannong 2 and sisters' dealt with in this paper.The results show that ① the multi - spikelets and multi - grains cultivar ecotype can be selected for the climate conditions in Sichuan which are favourable to the differentiation and development of wheat spikes, ②the cultivar and cultivar type can be selected if the parents.low.middle and higth generations are grown in different soil ecological conditions;③only in conditions that can easily induce diseases can high disease - resistant cultivars be selected.
