  • In a study reported in this paper,the biological characteristics of 76 Ustilaginoidea virens strains from Sichuan-Chongqing region were investigated.Of these strains,12,16,14,9,12,5 and 8 were isolated from Nanchong,Xuanhan,Shuangliu,Fuling,Yongchuan,Bishan and Wansheng,respectively.The biological method was used to analyze the color,sporulation ability and growth rate of the isolates. Significance and correlation analyses of these biological characteristics were performed. Four kinds of color (white,yellow,yellow green and dark green) were detected in these isolates,of which yellow was the dominant pigment,accounting for 52.63% of the total. Isolates originating from different areas had significant difference in growth rate and sporulation;and isolates of different colors were significantly different in growth rate. In addition,sporulation of the isolates was negatively correlated with their growth rate.
