摘　　要：【目的】筛选出再生萌芽期耐热性好、再生能力强、产量高、适合于右江河谷"早稻+再生稻+秋种番茄"生产模式的再生稻品种,以满足当地农民的种植需求。【方法】以6个再生稻品种为试材进行田间筛选试验,比较不同品种主要农艺性状及产量表现。【结果】除信丰优008和Y两优1号"早稻+再生稻"产量明显低于Ⅱ优63(CK),其他4个品种"早稻+再生稻"产量均高于Ⅱ优63,其中中浙优1号、准两优1141和Y两优5867三个品种"早稻+再生稻"产量分别为13889.6、13836.7和13382.1kg/ha,分别比Ⅱ优63增产9.60%、9.19%、5.60%;深两优581"4早稻+再生稻"产量为12849.6kg/ha,比Ⅱ优63增产1.40%;Y两优1号和信丰优00"8早稻+再生稻"产量分别为11474.2和9979.2kg/ha,分别比Ⅱ优63减产9.46%和21.25%。【结论】中浙优1号和准两优1141两个品种综合表现最好,可作为"早稻+再生稻+秋种番茄"生产模式下早播再生稻田主选品种;Y两优5867和深两优5814两个品种综合表现优良,可作为"早稻+再生稻+秋种番茄"生产模式下中、迟播再生稻田主选品种。[Objective]The purpose of this experiment was to screen out elite ratoon rice varieties suitable for the production mode ＂early rice＋ ratoon rice＋ autumn tomato＂ in Youjiang Valley, with good thermostability at germination stage,strong regeneration capacity and high yielding to meet needs of local farmers. [Method]Six rice varieties were tested in field to compare the agronomic traits and yield. [Result]Except Xinfengyou 008 and Y-Liangyou 1, the yields of early rice ＋ ration rice of other four rice varieties were higher than the CK, among which the yields of Zhongzheyou 1, Zhunliangyou 1141 and Y-Liangyou 5867 were13889.6,13836.7 and 13382.1 kg/ha with significant increase of 9.60, 9.19 and 5.60%, respectively, while the yield of Shenliangyou 5814 was 12849.6 kg/ha with only 1.40% increment. The yields of Y-Liangyou 1 and Xinfengyou 008 were 11474.2 and 9979.2 kg/ha and showed significant decrease of 9.46% and 21.25%, respectively. [Conclusion]Zhongzheyou 1 and Zhunliangyou 1141 displayed the best comprehensive performance, followed by Y-Liangyou 5867 and Shenliangyou 5814, the former could be used as main early-seeding ratoon rice varieties, the latter could be used as mid- and late-seeding ratoon rice vareties under production mode ＂early rice＋ rationing rice＋ autumn tomato＂.
