ABSTRACT
Blast has been a continuous threat to finger millet production in
semi-arid tropics. The disease is economically important and widespread in
finger millet major growing areas of western, Nyanza and Rift valley in Kenya.
Host resistance is the most economical and effective means of controlling the
disease as finger millet is grown by resource-poor farmers. This study
evaluated a hundred finger millet genotypes for resistance to blast at KALRO (Kenya
Agricultural Research and Livestock Organization) Kakamega and Alupe, Kenya for two seasons in
2011/2012 in a lattice square design for two seasons each. Data on blast
incidence and severity were measured. Data were analyzed using ANOVA (analysis
of variance) and means separated using Duncan multiple range test (DMRT) at p<0.005. The results showed that
disease severity was highest in early maturing varieties and lowest in the late
maturing varieties. The most resistant genotypes were: GBK000702, GBK000513, GBK029869, GULU-E, GBK000752 and Busibwabo.
Pearson correlation analysis between neck severity and physiological maturity
was positively significant (r=-0.47).
A strong positive correlation between finger severity and neck severity (r= 0.87) was observed. These tolerant
genotypes could be utilized as donor parents for breeding durable blast
resistant varieties.
