摘要: 以新德优8258、天优华占和丰乐4号为试验材料,比较3个再生稻品种的产量(头季、再生季和周年)及稻米品质(外观和加工),研究再生稻整精米率的主要影响因子,筛选出适合湖北省洪湖市种植的优质品种。结果表明,新德优8258的头季稻产量显著高于天优华占和丰乐4号,而天优华占的再生季产量最高,产量达5 971.4 kg/hm2,新德优8258再生季产量最低,产量为4 238.7 kg/hm2,但品种间两季总产量无显著差异。新德优8258的再生稻米糙米率、精米率和整精米率均最高,分别为80.1%、68.8%和62.9%,且均显著高于丰乐4号。天优华占与丰乐4号的垩白粒率有显著差异,与新德优8258和丰乐4号的长宽比均有显著差异。相关分析表明,3个品种再生稻米的整精米率与糙米率和精米率极显著正相关(P=0.001),与垩白粒率呈显著负相关(P=-0.712)。在保证两季总产量的前提下,新德优8258和天优华占比丰乐4号的再生稻米整精米率高,更适宜在洪湖地区种植。

Abstract: In order to explore the main factors affecting the ratooning rice whole polished rice rate, and select the high-quality ratooning rice varieties suitable for Honghu city in Hubei province, using Xindeyou 8258, Tianyouhuazhan and Fengle No.4 as experimental materials, the processing quality and appearance quality of three ratooning rice varieties were compared. The results showed that the first-season rice yield of Xindeyou 8258 was significantly higher than that of Tianyouhuazhan and Fengle No.4, while Tianyouhuazhan had the highest yield in the ratooning season, with a yield of 5 971.4 kg/hm2. The yield of Xindeyou 8258 was the lowest, with a yield of 4 238.7 kg/hm2, but there is no significant difference in the total yield between the two seasons. The brown rice rate, polished rice rate and whole rice rate of Xindeyou 8258 were the highest, which were 80.1%, 68.8% and 62.9% respectively, and they were all significantly higher than Fengle No.4. The chalky interest rates of Tianyouhuazhan and Fengle No.4 were significantly different, and the aspect ratios of Xindeyou 8258 and Fengle No.4 were significantly different. Correlation analysis showed that the head rice rate of each variety of ratooning rice was extremely significantly positively correlated with the brown rice rate and polished rice rate (P=0.001), and was significantly negatively correlated with the chalky rate (P=-0.712). Under the premise of ensuring the total yield, Xindeyou 8258 and Tianyouhuazhan whole polished rice rate than Fengle No.4. Therefore, Xindeyou 8258 and Tianyouhuazhan were more suitable for planting in Honghu area.
