Abstract:

Baigengzhan is a new thermo-sensitive inbred rice variety carrying xa-5 gene against the virulent pathotype V of rice bacterial blight and blast, derived from the local breeding material with fine quality and high yield. It showed good resistance to the virulent pathotype V of rice bacterial blight and blast, grain quality as provincial standard level 3, and high yield equaled to the control variety Yuxiangyouzhan in the regional trial of Guangdong Province. Baigengzhan can be planted as early season rice in all Guangdong Province except northern area, particularly suitable for the epidemic area of the virulence pathotype V of bacterial blight, such as Jiangmen, Yangjiang, Zhanjiang and Leizhou Peninsula.

Key words: rice, Baigengzhan, breeding, pathotype V of rice bacterial blight
