ABSTRACT
Beans play a significant role in food security owing to its nutritional value and generation of income. However, output of beans in Western Kenya is hindered by diseases, pests, soil infertility and unfavorable weather resulting to low productivity. Of the many diseases of beans, common bacterial blight (CBB) caused by Xanthomonas axonopodis pv. phaseoli (Xap) is a disease of economic importance in common beans (Phaseolus vulgaris L.). Due to the fact that chemicals have not been effective against CBB, the use of resistant genotypes is a central management strategy. The current study was carried out in the field and in the green house of KALRO-Kakamega in 2013 and 2014 to screen nine bean genotypes for resistance to common bacterial blight disease. Experiments were conducted in randomized complete block design with three replications in a 9×2×2 factorial factor during the greenhouse and field screening and 4×2×2×2 field experiment when assessing the role of soil amendments and method of cropping on disease incidence and severity. During growth, data on plant height, number of pods/plant, length of pods and size and number of CBB spots was taken. Yield parameters were also assessed. During the study, the isolates that were recovered from leaf samples were categorized as Xanthomonas like, with regard to their yellow pigment and convex mucoid morphology. Reaction to Xap was assessed as the number of spots on the leaves and diseased leaf area (DLA). The findings from the experiment revealed a significant variation (P
