Abstract
Studies on inoculum densities of the chickpea wilt pathogen F. oxysporum f.sp. ciceris race 1 and 2 with 3 chickpea cultivars representing early wilter (highly susceptible), late wilter (moderately susceptible) and resistant were conducted in a glasshouse at 25°C. Highly susceptible cv. JG 62 showed 100% mortality at 15 days for race 1 and 17 days for race 2 at higher inoculum density. At the low inoculum density, the wilting was delayed and at this inoculum level 2 other cultivars showed no mortality. The wilt resistant cultivar cv. WR 315 and moderately susceptible cultivar cv. K 850 remained completely free from wilt symptoms for up to 60 days while cv. JG 62 wilted in 27 days with F. o. f.sp. ciceris populations ranging from 4233 to 4667 propagules/g soil. Xylem browning in the root and collar region was recorded in cv. K 850. The F. o. f.sp. ciceris population of race 1 and 2 increased with age of the plant in soils with wilt susceptible, moderately susceptible and resistant chickpea cultivars. Moderately susceptible and resistant cultivars supported the multiplication of F. o. f.sp. ciceris propagules in the soil though the plants were free of wilt symptoms for up to 60 days after planting. The multiplication ratio was higher at low inoculum density of the propagules compared with the higher inoculum density for both the races of F.o. f.sp. ciceris. As the inoculum density increased the multiplication ratio decreased.
