摘要：

针对鄂东地区再生稻生产缺乏适宜品种、再生力评价指标不明确、鉴定方法不统一等突出问题，为筛选适配当地生态条件的再生稻品种、构建科学高效的再生力评价体系。以23个杂交稻品种为试验材料，于2023年在黄冈市进行田间试验，分析生育期、农艺性状及产量，并通过回归分析确立再生力鉴定评价关键指标。结果表明：供试品种全生育期为184~213 d，均能安全成熟；再生芽出鞘率变异最大(8.5%~85.6%，CV=43%)，且与产量显著相关(R2=0.902)。依据再生季产量1350~4500 kg/hm2将再生力划分为4级，其中头季收获后第7天再生芽出鞘率、再生季有效穗数和最高苗期单苗分蘖数的分级准确率分别为68.75%、70.25%和47.38%，可作为核心筛选指标。综合评价表明，‘荆楚优89’、‘E两优88’等16个品种生育期适宜、再生力强、丰产性好，其中‘E两优88’、‘芯香两优3927’等4个品种两季总产超13000 kg/hm2，综合表现最优。本研究明确了鄂东再生稻品种筛选的核心指标与评价体系，筛选出一批适宜规模化推广的优良品种，可为当地再生稻品种选用与高效栽培提供科学依据。未来可结合多年多点试验进一步优化评价体系，强化抗逆与品质性状协同评价。

Abstract:

In view of the lack of suitable varieties for ratooning rice production in eastern Hubei, the evaluation index of ratooning ability is not clear, and the identification methods are not unified，the study aims to screen suitable ratoon rice varieties in eastern Hubei and establish an evaluation system for ratooning ability. A field trial was conducted in Huanggang City in 2023 using 23 hybrid rice varieties as materials. The growth duration, agronomic traits and yield were analyzed, and key indicators for evaluating ratooning ability were identified through regression analysis. The growth period of the tested varieties ranged from 184 to 213 days, with the regeneration bud emergence rate showing the greatest variation (8.5%-85.6%, CV=43%) and significantly correlated with yield (R2=0.902). Based on ratoon season yields (1350 to 4500 kg/hm2), ratooning ability was classified into four grades. Among the indicators, the regeneration bud emergence rate on the 7th day after harvest of the main crop, the number of effective panicles in the ratoon season, and the tiller number per seedling at the maximum seedling stage achieved classification accuracy rates of 68.75%, 70.25% and 47.38%, respectively, allowing them to serve as core screening indicators. 16 varieties, such as ‘Jingchuyou 89’, ‘E Liangyou 88’, were identified as suitable varieties for cultivation. Among them, 4 varieties, including ‘E Liangyou 88’, ‘Xinxiang Liangyou 3927’, Yuxiangyou 8133 and ‘Sheng Liangyou 311’, achieved total annual yields exceeding 13,000 kg/hm2, demonstrating outstanding yield performance. This study identified core indicators for evaluating ratooning ability and screened multiple suitable varieties, providing a scientific basis for selection and production of ratoon rice in eastern Hubei.
