Abstract

Following the downy mildew survey in 2000, a unique scientific collaboration between Eritrea, ICRISAT and the Centre for Ariz Zone Studies (CAZS) at Bangor, Wales, UK, has produced valuable data on the resistance of 70 pearl millet genotypes to an Eritrean isolate of the pathogen (Sclerospora graminicola). Screening of the genotypes, which included Eritrean landraces and promising new cultivars from ICRISAT populations, was done in a tropical greenhouse at the CAZS. Susceptible control genotypes 7042(S) and HB 3 showed approximately 50% infection (rather less than expected), and the resistant control genotype P 7-3 proved surprisingly susceptible to this isolate of the pathogen. The Bultug Keren landrace was particularly susceptible with an overall mean infection of 79.5%. Three introduced male-sterile lines (ICMA 98333, ICMA 92444 and ICMA 00888) had 0% infection, while three other introductions (ICMA 99111, P 1449-2 and P 310-17B) showed <2% downy mildew incidence.
