摘　　要：采用恢复基因的累加和有利优势因子的转育相结合方法育成的优质早籼恢复系Ｔ０９７４，具有恢复力强、配合力高、生育期短、抗逆性较强、米质好、花粉量大、花粉外散率高等特点。利用该恢复系所配组合具有熟期早、米质优、产量高、适应性广等特征。现已通过地区级审定的组合有威优９７４、Ⅰ优９７４和金优９７４。T0974, derived from the cross of Ce 64 /// Suweon 287∥Erliuzaizhao/T0498, is a newly-developed indica restorer line in rice with fine quality and early maturity. It has the characteristics of strong restoring ability, good combining ability, early maturity, strong stress tolerance, good grain quality, heavy pollen load and high rate of out-shed pollen grains. The hybrids of the restorer line T0974 showed early maturity (suitable as early rice in double rice cropping system), fine quality, high yield potential and wide adaptability. Among the hybrids of T0974, Weiyou 974, I You 974 and Jinyou 974 have been examined and released to farmers and show a good prospect for commercial production as early hybrid rice.
