| 摘 要： | 浙优10号是BT型不育系8204A与恢复系浙恢9816配组选育成的高产杂交晚粳新组合,其中浙恢9816由恢复系浙恢93-1与皖恢9号杂交后经5a的加代选育获得。2003年-2004年参加浙江省单季杂交粳稻区域试验,平均产量8.085t/hm2,比对照秀水63平均增产5.4%。2008年1月通过浙江省农作物品种审定委员审定。浙优10号具有植株繁茂,杆粗抗倒,穗大粒多,高产稳产,生育期适中,中抗稻瘟病,米质较优等特点,适宜在浙江省作单季晚稻推广应用。

| Abstract: | Zheyou 10, a new Late-cropping Japonica Hybrid Rice Combination with High Yield and Good Grain Quality was developed by crossing 8204A （ a late japonica BT CMS line） with the restorer line Zhehui9816. Zhehui9816 was developed by crossing Zhehui93-1 with Wanhui 9 through 5 years, It yielded an average of 8.085 t/hm^2 in two years （2003＆ 2004） of the regional yield trials for Late- cropping Japonica Hybrid Rice of Zhejiang Province, 5. 4% higher than that of the check Xiushui63. Consequently, it was registered and released for commercial production in Zhejiang Province at January of 2008. Zheyou 10 showed vigorous heterosis, high yielding potential, large panicle, lodging resistance, good grain quality and timely discoloring in late stage. |
