| Abstract: | Three isolates from shaanxi major pepper growing regions were tested,which revealed that the pathogen of phytophthora blight of pepper is phytophothora capsici and have not found the other species of phytophthora.Sporangia are very variable in size and shape,ovoid,ellipsoidal ect,Length/breadth ratio 1.5-1.6,cohspicuously papillate,not proliferating internally,caudcous and with a long pedical.The causal organism is able to grow at 1:8×106 of malachite green, host range wide.Besides,the relative virence of three isolates of phytophthora capsici from diverse geographic origins was evaluated,ph1 was the highly virulent and was more appropriate to evaluate resistance. |
