1. Enhancing cowpea productivity and
production in drought-prone areas in sub-
Saharan Africa

7. Six elite cowpea lines introduced from IITA
showed complete immunity to Striga gesnerioides
in Magaria-Niger where the infestation was the
highest. These resistant lines are: IT98K-1092-1,
IT99K-573-1-1, IT98K-628, IT99K-1122,
IT97K-205-8, and IT97K-499-38.
8. In Nigeria seven IITA developed elite breeding
lines also showed no Striga emergence during the
two dates of planting: IT99K-573-1-1,
I T 9 9 K - 11 2 2 , I T 9 9 K - 4 9 4 - 6 , I T 0 4 - 2 2 7 - 4 ,
IT00K-1207, IT97K-819-118 and IT99K-529-2.
Two of these (IT99K-573-1-1 and IT99K-1122)
were also immune to Striga in Magaria-Niger.
9. Some farmers attracted to one of the test lines that showed
promise of producing grain in the drought prone area of
Hombolo. This cowpea line was at podding stage during the
second planting when there was terminal drought.

27. Crosses made between drought tolerant lines and some
breeding lines selected through FPVS
Selected lines had:
: lower seed yield reduction due to drought
: high seedling recovery

30. Crosses made
• 38 single crosses, F4 generation in the field
• 88 three way crosses, F3 generation in the field
• Seeds for F5 and F4 generations available
January 2010 for planting in Kano under
irrigation
31. Training
The following students are about completing their MSc
degree programs in plant breeding:
Mozambique: Henriques Colial and John Kaunda
Tanzania: Didasi Tarimo and Kimaro
Nigeria: Habibu Aliyu and Auwalu Adamu Umar
Mali and Niger: Nominated students (Sory Diallo and
Mamadou Diallo, Mali and Mohammed Bouzou and
Moussa Bachari, Niger) could not get admitted for
graduate studies
40. Lessons learnt
• Training at MSc level
• The involvement of farmers, farmers’ groups and other
stakeholders such as extension agents and NGOs help in getting
developed technologies to where they would make necessary
impacts. NGO’s, entrepreneurs and local Government officials
were found helpful in pushing technologies to rural areas where
most cowpea farmers are located.
• Demonstration plots were found useful in getting farmers to
accept improved lines more readily
• Need to survey the diseases of cowpea in ESA.
