McKnight Foundation Collaborative Crops Research Project No: 06-741 the three Tanzania sites. From this study the cowpeas that are resistant at Bihawana are also resistant at Singida and Ismani. In Malawi it appears that Alectra from Bunda and Kasungu are similar but different to Zomba. It has to be also noted that the Alectra samples we have from Malawi are different from the parasite collected further south near Blantyre as in trials some time back at Long Ashton this attacked B301 (Mainjeni, 1999). It has been more confusing to find the result for IT81D-994 as this was resistant to all samples in 2008. There must be something went wrong with the samples delivered to Long Ashton this year. The most reliable method for characterization of these strains would be to go for using molecular markers. Reference: Mainjeni, C. E. (1999) The host range of Alectra vogelii Benth.

Output 1.4: Collaboration in cowpea research increased in Southern Africa Project activities are leading to increased capacity in cowpea research in Malawi and Tanzania and the strengthening of collaboration between institutions in both countries. Within the project, two researchers Abubakar Mzanda from Tanzania and Dr Vernon Kabambe from Malawi participated in a week long statistics training course offered by McKnight Foundation at Centre for Agricultural Research Development (CARD)Bunda College University of Malawi June 15-22, 2009. • Two project staff – Drs J.P. Hella and V Kabamabe attended ASARECA review workshop on climate change. The workshop was held at Naivasha Kenya. • A paper titled “assessment of Cowpea Marketing Efficiency: A case study of selected regions in Tanzania” by Gabriel, M.; Hella, J.P. and Mbwaga, A.M was presented at the Annual Agricultural Economists Society of Tanzania (AGREST) held in Zanzibar and will appear in AGREST conference series Vol. 8. (in press). The proceedings will be ready within and outside the country. Mr Gabriel Martin’s got financial support from the project for his MSc research work • Group dynamics training was conducted for all the farmers in the two participating villages in Mgwangwa. The training was conducted in August 2009. The training was provided on group leadership and operation. This group strengthening included membership and responsibilities, constitution, networking and fund raising to sustain the groups. • During the season an undergraduate student (Ms Elida Kazira )undertook a study on cowpea time of planting x variety x density trial titled - Farmer Participatory Selection of Alectra Resistant Cowpea Varieties in Selected Districts of Malawi). The student has submitted her thesis for examination. • Participatory video workshop was held at INADES Dodoma, where two extension staff from the projects sites Dodoma and Iringa respectively participated and these also went back and trained farmers from the groups at Mangalali Iringa (14 farmers) and Kikombo in Dodoma (12 farmers) 11 2009
