Xieyou 963, a New late Indica Hybrid Rice combination

Xieyou 963 is a new late indica hybrid rice combination selected by crop Institute of Zhejiang Academy of Agricultural Sciences (zip code: 310021) in 1996. According to the regional test of late indica rice in Zhejiang Province in 1998 and 1999, the average yield per 667m2 (1 mu) was 516.35 kg and 466.95 kg respectively, which was 13.74% and 9.65% higher than that of Shanyou 10, and the production test in 1999 showed an average yield of 450.9 kg per 667m. 8.78% higher than the control Shanyou 10. The average whole growth period was 128.2 days, which was 0.3 days longer than that of Shanyou 10. The results of resistance identification showed that it was resistant to rice blast, moderately resistant to brown planthopper, susceptible to bacterial blight, fine stripe and white-backed planthopper. The physical and chemical indexes of rice quality were similar to those of Shanyou 10, in which five indexes such as brown rice rate, milled rice rate, grain length, transparency and alkali elimination value reached the first class standard of edible high quality rice issued by the Ministry. The combination has strong tillering ability and more effective panicles. The panicle type is larger and the yield of seed production is high. The combination was approved by Zhejiang crop Variety approval Committee in April 2000. It is suitable for planting hybrid rice in the whole province.
