湖北省水稻育种研究进展与展望
摘要：解放后湖北省水稻（Qryza satita L.）育种取得了重大的成就，例如光温敏核不育水稻的发现与应用研究，新型雄性核不育细胞质资源的发现，提出中间材料使用方法、产量与抗病性的同步筛选，创造出亚籼粳杂交法，摸索出五结合单株选择法，选育了一批推广品种，这些对水稻乃至整个作物杂种优势利用影响重大，为水稻的增产、增收做出了重大贡献。湖北当前在稻瘟病抗性育种方面取得了进展，但产量育种处于徘徊境地。以后重点是加强常规稻育种、强化水稻育种的基础研究、开展籼粳杂交研究、提高产量育种水平。

Abstract： After liberation， Hubei province has made remarkable achievements in rice breeding， such as the discovery and application of P（T）GMS rice（photo-/thermo-sensitive genic male-sterile rice）， Hubei found new nuclear male sterile cytoplasm resources， put forward the synchronizing screening of the usage， yield and disease resistance of the middle materials， created Indica-japonica hybridization method and explored the individual selection method of 5 kinds of combination， selected and bred a batch of extension varieties， these achievements have significant influence on rice and the entire heterosis utilization， and made a major contribution for increasing production and incomes of rice. Currently Hubei province has made positive progress in blast resistance breeding， but still was wandering in yield breeding. From now on the focus is to strengthen the conventional rice breeding， intensify the basis research of rice breeding， carry out Indica-japonica hybridization research， and improve the level of yield breeding.
