摘要 [目的]为筛选出适合广东省江门市恩平市种植的优质、高产、抗病水稻新品种、满足广大种植户对水稻新品种的需求;为丰富当地水稻品种，提高水稻产量和品质以及推广应用提供科学依据。[方法]通过田间试验，比较E14、E19、G9、粤晶丝苗2号（对照）、玉晶油占、固广油占、粤银软占、粤航新占、华航56号、华航51号共10个品种的生育期、主要农艺性状、抗逆性和产量。[结果]各品种生育期为109～118 d，其中熟期最早的品种是华航56号，全生育期109 d;E14、粤航新占、华航51号熟期也较早，全生育期111 d。粤航新占、华航56号、华航51号3个品种产量均为5 836.20 kg/hm2，比对照增产834.00 kg/hm2，增产率16.67%;而其余品种比对照种减产，减产率在3.33%～20.00%。参试品种抗病性和抗倒伏性强。[结论]在恩平市，华航56号综合表现较好，其次是粤航新占，因此可在当地进一步推广。

Abstract [Objective]To screen new varieties of rice with high quality， high yield， disease resistance and suitable for cultivation in Enping， and to meet the needs of farmers for new varieties of rice， to provide scientific basis for enriching local varieties of rice， improve rice yield and quality， popularization and application. [Method]A total of 10 rice varieties were used for variety comparison experiment to determine yielding ability， stress resistance and adaptability of different varieties. [Result]The whole growth period of tested cultivars ranged from 109 to 118 d. The earliest variety was Huahang 56， with a whole growth period of 109 d. E14， Yuehangxinzhan and Huahang 51 also showed a relatively short growth period of 111 d. All three varieties of Yuehangxinzhan，Huahang 51 and Huahang 56 had the highest yield，which was 5 836.20 kg/hm2， and increased by 834.00 kg/hm2 compared with that of  control with the inreasing rate being 16.67%. The yield of other varieties decreased by 3.33%-20.00% compared with that of control. The tested cultivars had strong disease resistance and lodging resistance. [Conclusion]Huahang 56 had a better overall performance， followed by Yuehangxinzhan， which could be further promoted in Enping City.

恩平市是廣东省40个产粮大县之一，水稻年播种面积2.8万/hm2以上[1]。恩平市常年种植双季稻，是广东省优质大米主要生产基地之一[2-3]，水稻是恩平市主要粮食生产作物之一。恩平市属南亚热带季风海洋性气候，冬短夏长，冬暖夏凉，日照充足，雨量充沛，优越的自然环境促进了当地发展优质水稻产业，但优质水稻生产还需要长期大量的资金投入、不断培育优良水稻品种、研究配套高产栽培技术、狠抓主栽品种的推广应用等[4]。

推广适应当地种植的优质高产水稻品种有利于推动水稻转型升级，促进水稻产业持续稳定发展[5]。……
