How is the rice variety Feiyou 600?

Feiyou 600 is a hybrid late indica rice variety developed by researcher Cheng Shihua and others in 1999 by crossing Feigai A with R600. This combination has medium tillering ability, large panicles with many grains, a relatively high 1000-grain weight, good yield potential, and relatively low fertilizer requirements. Its resistance to rice blast is significantly better than that of the control, its grain quality is slightly better than that of the control Shanyou 63, and its seed production yield is relatively high. It is suitable for single-season rice cultivation in Zhejiang Province, and in southern Zhejiang it can be grown as continuous late rice. In cultivation, attention should be paid to preventing lodging and controlling bacterial leaf blight. In the 2001 and 2002 Zhejiang Province single-season hybrid indica rice regional trials, the two-year average yield per mu was 523.1 kg, an increase of 6.1% over the control Shanyou 63. The two-year average whole growth period was 133.7 days, 2.4 days shorter than that of the control.
