2023年皖西南地区水稻新品种筛选试验

Screening test of new rice varieties in southwest Anhui Province in 2023

为筛选适宜皖西南地区种植的水稻新品种,本研究对Y两优9826等24个水稻新品种的生育期、种植表现以及产量等进行比较,研究分析其综合表现。结果表明,各品种生育期120~138d,多数品种生育期130d,有效穗数200.1万~330.3万/hm^(2),结实率70.4%~92.8%;各品种实际产量为7851.0~12426.0 kg/hm^(2)。综合各品种生长表现,品种林两优1771、荃优879、万丰优818、玮两优8612和晶两优8612的产量较高,综合性状好,可在该地区进行推广种植。

In order to screen suitable new rice varieties for cultivation in the southwestern region of Anhui province,this study compared the growth period,planting performance,and yield of 24 rice varieties including Y Liangyou 9826.The results showed that the growth period of each variety was 120-138 days,with most varieties having a growth period of 130 days.The effective panicle number was 2.01 million to 3.303 million/hm^(2),and the seed setting rate was 70.4% to 92.8%;the actual yield of each variety was 7851.0-12426.0 kg/hm^(2).Based on the growth performance of various varieties,the selected varieties,Linliangyou 1771,Quanyou 879,Wanfengyou 818,Weiliangyou 8612,and Jingliangyou 8612 had high yields and good comprehensive characteristics,and could be promoted as new rice varieties in the region.
