Description Twenty Pennisetum americanum cvs., identified from > 4000 germ plasm accessions as relatively less susceptible to Claviceps fusiformis, were intermated and the progenies of these crosses were screened for resistance at each generation from F2 to F6. No F2 populations had a mean ergot severity of < 20%, but when individual inflorescences which had little or no ergot were selected at each generation, to provide selfed seed for the next generation, resistance levels increased steadily. At F6, 27 of 98 lines had no more than 1% mean ergot severity, an additional 29 F6 lines had mean ergot severities of 2-10%, and susceptible checks showed 76-95% severity. This assembly of resistance factors is indicative of the rich genetic diversity in the P. americanum collection
