Experiments were conducted at Arsi Negele, Ethiopia, during the 1988 and 1989 rainy seasons to determine a suitable combination of sorghum panicle trimming (a method used to remove pollinated spikelets), inoculation, and bagging to develop an ergot resistance screening technique. Results showed that the most suitable method was a single inoculation...

... Our findings indicate that a concentration of 10 6 conidia/mL was optimum for infection of the male sterile line used in this study, and that higher concentrations did not result in significantly higher infection levels. Conidial concentrations of ~10 6 conidia/mL were used by Tegegne et al. (1994), Musabyimana et al. (1995) and Reed et al. (2002) in their studies to identify resistant germplasm of Sorghum and other grass genera to C. africana. Workneh and Rush (2006) considered that the use of conidial concentrations of 10 5 and 10 6 conidia/mL in their predictive model may result in an overestimation of ergot severity. ...
