Yueyou 938 is a new indica hybrid combination developed in 1993 from Yuetai A, a Honglian-type CMS line, crossed to the restorer line R938. It was registered and released by Jiangsu Crops Variety Examination & Approval Committee in 2000. The hybrid yielded 9.06 and 9.93 t/hm 2 with a yield increase of 6.5% and 7.5% over the check hybrid Shanyou 63 in the regional yield trials of Jiangsu Province in 1997 and 1998, respectively. All of its grain processing, appearance and cooking quality characters are up to the Quality Rice Product Standards by GB/T17891 1999. It has also an intermediate resistance to both 4 strains of bacterial leaf blight and 3 races of rice blast. Besides, the hybrid is characteristic of large panicle, high seed setting percentage, good ripening appearance. It is 5～7 days longer in maturity than Shanyou 63 and can be widely used in the single crop indica growing area of the Yangtze River Valley.
