  3. Research Background Cowpea (a poor man’s meat), is an economically important legume crop grown widely in the Semi-Arid regions. Fresh pods Fresh pod meal Fresh pods read for market Cowpea bread Quality grains Cowpea flour

  4. Background Cont’d Storage pests Cowpea aphid Foliar chewing pests Cowpea leaf blight The major constraints to production and productivity of cowpea Cowpea scab

  5. Research Objective This study was designed to contribute to enhancement of cowpea production through screening cowpea lines for different crop attributes including agronomic performance, pod and grain yield, and resistance/tolerance to cowpea scab.

  6. Materials and methods Eleven (11) cowpea lines comprising four improved local varieties and seven promising lines were evaluated. Field evaluations for yield and growth attributes were carried out in the second rains of 2010, the two rain seasons of 2011 and in the first rain of 2012

  7. Materials and methods FIELD RESISTANCE / TOLERANCE TRIALS

  8. Research Results Average Means of the agronomic traits of the promising cowpea lines in relation to SECOW 2W measured in 2010 and 2011 growing seasons

  9. Results cont’d Average Means of the yield components and grain yield of the promising cowpea lines in relation to SECOW 2W measured in 2010 and 2011 growing seasons

  10. Results cont’d Differences in weather condition in 2010, 2011and 2012 growing seasons

  11. Results cont’d

  12. Conclusions Majority of the promising lines were either erect or semi-erect Only two promising lines (ACC25 and ACC26) that out yielded SECOW 2W Cowpea lines (SECOW 3B, SECOW 4W, SECOW 2W, ACC11, ACC12 and ACC2 that showed good resistance response
