徐优201(徐9320A×徐恢201)是一个优质高产杂交中粳新组合。2003—2004年参加江苏省杂交中粳区试和生产试验,2 a区试平均比对照9优138增产6.44%,生产试验比对照增产13.94%。大面积种植产量在9.50 t/hm2左右。米质理化指标达国标3级优质稻谷标准。该组合还表现株型优良,长势繁茂,穗大粒多,灌浆速度快,结实率高,抗病抗倒性强,高产稳产性好,适应性广。2005年2月通过江苏省农作物品种审定。
Xuyou 201 （Xu 9320A/Xuhui 201 ） was a new japonica hybrid rice combination with high yield and good grain quality. It yielded 6.44% and 13.94% higher than the check hybrid 9 You 138 in the regional yield trials （two years） and the productional trial of Jiangsu Province, respectively. In large-scale production, its yield level was about 9.5 t/hm^2 . The grain quality of Xuyou 201 was up to the state standards of the 3^rd class fine quality rice. In addition, it had a good plant type, big panicles with many spikelets, a high seed-setting percentage, strong disease and lodging resistances, and a wide adaptability.
