基于52份优质籼型杂交稻的湖北省再生稻适宜品种筛选
Screening of suitable varieties for ratooning rice in Hubei Province based on 52 high-quality indica hybrid rice
摘要
Abstract
In order to screen the ratooning rice varieties suitable for the climate and mechanical harvesting mode in Hubei Province,52 indica hybrid rice varieties mainly promoted in the Yangtze River Basin were used as materials,and Fengliangyouxiang 1 was used as the control.Field experiments were carried out in Wuxue City in 2024 to analyze the growth period,yield traits,regeneration ability and yield components of each variety.The results showed that the traits of the tested varieties were significantly different,and most of the growth periods were suitable for the light and temperature conditions in Hubei Province.The average yield of the main season rice was 8.25 t/hm2,and 45 varieties/combinations increased yield compared with the control.The average yield of ratooning rice was 3.45 t/hm2,and only 11 varieties/combinations were higher than the control.The average annual total yield was 11.70 t/hm2,and the annual total yield of 33 varieties/combinations was higher than that of the control.Among them,Gongliangyou 892,Zhuyou 995 and Yongyou 4949 ranked the top three of the annual total yield,and Yongyou 4949 had a balanced yield performance in the two seasons.In terms of yield composition,the core determinant of the main season rice was the number of spikelets per panicle,and the core determinant of the ratooning season rice was the number of effective panicles.The increase of the number of effective panicles in the ratooning season rice was likely to lead to a decrease in seed setting rate.The selected varieties/combinations such as Gongliangyou 892 provided materi-al support and a theoretical basis for the layout and breeding of ratoon rice varieties in Hubei Province.关键词
