Identification of Phytophthora capsici resistance and main agronomical traits of pepper resources from AVRDC

22 pepper germplasm materials introduced from AVRDC were evaluated for resistance to Phytophthora capsici isolate of Guangdong Province by root-irrigation method and their major agronomic characters were observed concurrently.The result showed that 18 materials were resistant to the isolate ZLT0566 which was isolated from Guangdong.Among them,7 resistant resources showed immune or highly resistant level.A similar results were obtained by the field assessment.However,most of the resistant materials introduced had too small fruit except Bangchang,a cultivar from Thailand,which had some commodity values due to its larger fruit size.It is necessary to improve the fruit characteristicof these resistant materials.
