摘　　要：通过筛选41个具备再生稻生产潜力的品种,考察其生育期的适应性、产量、最终再生率,并采用算术平均法对各项指标进行赋值,综合评价参选品种作为再生稻的生产潜力。结果显示:参选品种生育期均适合长江中下游地区再生稻种植的要求,其中,桃优77、桃优香占在10月初成熟,为三熟制提供了较好的条件;基于赋值量化数据,筛选出筑两优慧占、华浙优1号、悦两优钰占、珂两优1019、玮两优8612等12个品种,作为长江中下游地区再生稻后续验证的品种;再生稻的最终再生率与再生季产量、总产量、总产量赋值、总赋值呈显著或极显著正相关,说明该量化评价方法具有较高的可行性和参考价值。Forty-one ratooning rice varieties with potential productivity were screened out,and the adaptability of growth period,yield and final regeneration rate was investigated.The index assignment was carried out by arithmetic average method to comprehensively evaluate the production potential of the test varieties as ratooning rice.The results showed that the growth period of all varieties was suitable for the requirements of ratooning rice planting in the Middle and lower reaches of the Yangtze River.Taoyou 77 and Taoyouxiangzhan matured in early October,which provided better utilization conditions for the three-cropping system.Twelve varieties such as Zhuliangyouhuizhan,Huazheyou 1,Yueliangyouyuzhan,Keliangyou 1019 and Weiliangyou 8612 were selected as the ratooning rice varieties for further demonstration in the Middle and lower reaches of the Yangtze River based on assignment data.The final regeneration rate was significantly and extremely significantly positively correlated with the yield of the regeneration season,total yield,total yield assignment and total assignment,which show that the quantificational evaluation method has strong feasibility and reference value.
