Abstract:

At present, governments at all levels are closely monitoring food security and continuously introducing incentive policies to promote increased production. Regenerated rice, as a production measure to increase yield, is receiving attention from the government and planting entities. This article compares the regeneration ability and yield of seven hybrid medium rice varieties as regenerative rice, selects suitable varieties of regenerative rice for the Jiangnan region along the Yangtze River in Anhui, and promotes the improvement of local rice yield. The results showed that Xinliangyou 611 and Liuliangyou Xiang11 had strong regeneration ability, high yield, and the best overall performance; Xinliangyouxiang 128, Youliangyou 2152 and Quanyou 1606 have strong high node regeneration ability, and their yield performance during the regeneration season is higher than that of the control; The first season rice of Hanyou 116 and Hanyou 73 has higher yield, average regeneration ability, and lower yield in the regeneration season. Comparing the regeneration ability and yield performance of different rice varieties, when selecting regenerated rice varieties, the varieties with higher panicles per hectare in the first season will have higher yields in the two seasons.
