摘　　要：[目的]选育优质、高产水稻新品种,为提高广西优质稻的产量和品质奠定基础.[方法]2007～2008年对广西优质组生产试验中表现优异的黄华占分离植株进行两年4代系统选育后,2009～2010年进行品比试验,2011～2012年参加广西优质稻常规组区域试验和生产试验,观察其综合性状表现.[结果]优质稻新品种玉丝6号生育期早造127.5 d左右,晚造117.0 d左右,株高109.1 cm,穗长22.8 cm,每穗总粒数155.9粒,结实率73.5％,千粒重23.6 g.2010年早造、晚造分别进行品比试验,玉丝6号产量最高,分别为7449.00和7599.00 kg/ha,分别比对照柳沙油占202增产11.20％和8.10％.2011、2012年参加广西常规优质稻组区试,平均产量为7393.05和6630.00 kg/ha,分别比柳沙油占202增产2.05％和9.09％.玉丝6号具有高产、稳产、米质优、分蘖力强和适应性广等特点,于2013年6月通过广西农作物品种审定委员会审定.[结论]优质稻品种玉丝6号具有较好推广应用前景,适宜在桂南、桂中和气候相似的华南双季稻作区早、晚造种植.[Objective]The present study was aimed to order to improve yield and quality of fine grain quality rice in breed new high-quality and high-yield rice variety in Guangxi. [Method]The rice variety Yusi 6 was developed from excellent segregated plants of rice variety Huanghuazhan by using systematic selection of 4 generations during 2 years. The comprehensive trait performances of Yusi 6 were investigated in variety comparative test during 2009-2010 and Guangxi regional trial and production test during 2011-2012. [Result]The growth duration of new rice variety Yusi 6 was 127.5 d at early cropping and 117.0 d at late cropping, respectively. The variety was charactered by 109.1 em of plant height, 22.8 cm of panicle length, 155.9 grains per panicle, 73.5% of seed setting rate, and 23.6 g of 1000-grain weight. The yield of Yusi 6 presented the highest yield （7449.00 and 7599.00 kg/ha） in variety comparative test in 2010, which increased by 11.20% and 8.1% as compared to the control Liushayouzhan 202. The average yields of Yusi 6 were 7393.50 and 6630.00 kg/ha in Guangxi regional trial during 2011-2012, which increased by 2.05% and 9.09% as compared to the eontro]L Liushayouzhan 202. Being high-yield, stable yield, fine grain quality, stronger tillering ability and wide adaptability, etc., Yusi 6 was registered and certified by Guangxi Committee for Crop Variety Registration in June, 2013. [Conclusion]Yusi 6 has good extending and applying prospect, it is suitable for planting as early and late cropping in southern and central regions of Guangxi and double-cropping rice planting regions of South China with similar climatic condition.
