Report on comparison experiment of new hybrid rice combinations

In order to select hybrid rice combinations with high - yield, strong resistance and suitable growth period for double - cropping rice area, summarize advanced cultivation technology and guide local production, five new hybrid rice combinations were chosen in a comparison experiment. The results show that Wuyou308 has the highest yield, increase by 54.6% than CK （ Jinyou207 ）, Xinliangyou6380 has the second highest yield, increase by 37.9% than CK and then the Fuyou21, increase by 35.6% than CK, all the increases reach extremely remarkable level, which means these three combinations can be extended in double - cropping rice area of Liujiang County.
