Field experiments was conducted at Agarfa and Sinana District, south eastern part of Ethiopia with the
objective to evaluate faba beans varieties for chocolate spot disease resistant at Sinana and Agarfa district
during the main cropping season of 2014. The experiment was conducted using randomized complete block
design (RCBD) with three replications. The following Eight improved faba bean varieties Mosisaa, Moti,
Gebelcho, Hachalu, Shallo, Tumsa, Wolki and Degaga varieties were used in evaluating their performance.
Disease severity was recorded by 1-9 disease scale with 1 no symptom and 9 heavy infection from the middle
three rows of ten sample plants. Disease incidence was taken by counting the number of infected plants.
AUDPC and PSI were calculated from severity. The data were analyzed by SAS computer software version 9.1.3.
The result reveled that there were variations between the varieties for their chocolate spot resistant. Maximum
Chocolate spot severity, AUDPC and PSI data were recorded at Degaga, Hachalu and Gebelcho varieties at both
experimental sites while minimum disease severity, PSI and AUDPC data were recorded from Tumsa, Shallo
and Wolki varieties with a mean Severity of (11.85%, 20.05%), (11.79, 21.6%) and (13.58, 19.81%) at Sinana and
Agarfa Districts, respectively. The highest disease incidence was recorded from Hachalu (41.99%, 49.79%) and
Degaga (42.38%, 44.3%) at Senana and Agarfa district, respectively; while the lowest disease incidence was
recorded from Tumsa (15.5%, 20.52%) and Wolki (19.89%) varieties at Senana and Agarfa Districts, respectively.
The result of this study shows that Shallo, Wolki and Tumsa varieties were resistant to chocolate spot disease
while Degaga, Hachalu and Gebelcho were susceptible varieties. On the other hand Mosisaa and Moti varieties
were moderately resistant. Therefore from the result, Shallo variety was performing wall as compare to the
other and recommended to the local farmers.
