摘要
裸燕麦是燕麦属中的独立种。皮、裸燕麦种间杂交后代表现混合遗传，其杂交技术为：严格选用种质资源；采用剪颖杂交技术；注重稳定前各世代的连续单株粒选；用生物学产量和收获指数作为主选指标；加代繁殖，缩短育种周期。已用本技术育成系列优种；创制了具有特异性状的种质资源；明确了皮、裸燕麦种间杂交的一些遗传现象。
Avena nuda is an independent species of oats. Hybridizing progeny between Avena nuda and Avena sativa shows mixed inheritance. The hybridizing technique is to select and use genetic resources carefully;to use the cut glume- hybridizing technique;to lay stress on continuous single plant grain-selection before the change of the shape and properties of each generation;to use the output of a single plant and its grains and the harvest index as a main selection target;to increase numbers of propagating generation in one year in order to reduce the breeding time. A series of new varieties were bred successfully with this technique;the new genetic resources with special shape and properties were created; some hereditary phenomena about intersprecific hybridization between Avena nuda and Avena sative were defined.
