Yield components of high-yielding hybrid rice Xindao 22 were researched and the results indicated that seed rates, grain number per panicle, effective panicles and 1000-grain weight contributed to yield. Appropriate spike-grain structure to get yield over 9.0 t/hm2 which effective panicles were 3.475 millon/hm2, grain number per panicle were 132.5, seed rates was 90%and 1000-grain weight was 25 g.
