| Abstract: | The resistance to sheath blight (SB) of Shanyou 63 and the field invasion of the disease were surveyed and the correlation between infection of SB and yield loss was analyzed. The results showed that Shanyou 63 was of medium resistance to SB, and its resistance became effective in the medium-late growth stages. In general, the infecfion degree of SB was below grade 2, which had not much influence on grain yield. Through the demonstration of using the medium resistance of Shanyou 63 to control SB, it is concluded that the technique is effective, and it can decrease the times and amount of germicides applied. |
