摘　　要：为了给杂交稻新品种健优388的合理应用提供依据，利用2010-2011年国家南方稻区长江上游杂交水稻区域试验资料，对其丰产性、稳定性及产量构成因素进行分析。结果表明：健优388具有较好的丰产性，产量水平主要集中在8．05～10．00 t/hm2，平均有效穗234．7万/hm2，平均穗实粒数139．8粒，平均千粒重27．9 g；有效穗、穗实粒数与产量呈极显著正相关关系，千粒重与产量呈显著正相关关系；有效穗对产量的直接贡献最大，其次是穗实粒数，千粒重的作用最小。In order to provide a reference for rationally utilizing the new hybrid rice cultivar Jianyou 388,the data from the national regional test of Jianyou 388 from 2010 to 2011 were employed to analyze its yield ability,yield stability and yield components.Results：Jianyou 388 had higher yield,which focused on 8.05~10.00 t/hm2 ,the average effective panicle was 2 347 thousand/hm2 ,the average NFGP was 139.8 grains and the average thousand-grain weight was 27.9 g;the yield was of a significant positive correlation with effective panicle and NFGP,while thousand-grain weight and yield had a positive correlation;making the maximum contribution to yield waseffective panicle,next was NFGP,the last was thousand-grain weight.
