Minghui 63 is the new restorer line that I used IR30 as the female parent and Kyu 630 hybridized in the autumn of 1980. It belongs to the basic nutrition type. In the late season, the whole growth period is 137 days. The total accumulated temperature is 2450 ℃ -2500 ℃, which is about 5 days longer than that of IR24. The average total number of leaves is 16.5 leaves and spike length is 23.4 cm. Rate of 86.3%, grain weight of 29.3 grams, the grain was elongated wide, larger than the IR30, 630 than Gui, partial pale leaves, colorless sheaths, canopy leaves straight, slightly wider, the late transfer color, height 100 cm Around, on the ground section is short, not lodging. A strong resilience against wild defeat type A, resistance to rice blast, resistance to bacterial blight and planthopper. Shanyou 63 is Zhenshan 97A and Minghui 63 prepared hybrid
