皮、裸燕麦种间杂交育种的研究

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。

Hybridizing Breeding between Avena nuda and Avena sativa

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.
