经多点试验指出，二系杂交稻组合“衡两优一号”在海拔1000～1400m，年均温13．9～14．7℃的温凉地区表现出比该区域现有推广三系组合“汕优64”增产11．69％～19．19％，每公顷产量7770～10935kg，生育期与对照相当或缩短，抗性强，适于类似区域推广。栽培措施上予以改进，产量将进一步提高。
The results of multi-point experiments showed that the hybrid rice combination “Hengliangyou No.1” showed a higher yield than the existing three-line combination in the region in warm and cool areas with the average annual temperature of 13.9 ~ 14.7 ℃ at the altitude of 1000 ~ 1400m. “Shanyou 64” increased yield 11.69% ~ 19.19%, yield per hectare 7770 ~ 10935kg, growth period and the control of the equivalent or shortened, strong resistance, suitable for similar areas to promote. Cultivation measures to be improved, production will be further increased.
