Comparison test of new single-cropping semilate hybrid rice varieties

In this paper, a comparison test of 12 new introduced semilate hybrid rice varieties was conducted by using the design of single factor random block and with “Fengliangyou No.4” as control. The results showed that the yield of “Huifengyou3518” and “Guangliangyou1393” were significantly higher than that of control by 21.55% and 19.78%, respectively. Moreover, the above two varieties showed good comprehensive characters and could be continuously extended and demonstrated in future.
