ASS6 ASS64 ASS110 ASS56 Figure 5-9: Examples of AS-PCR mapping results The identified SNPs from cowpea ESTs linked to important traits have been converted into genetic markers. The converted SNPs are covering several regions of the cowpea genetic map, LG 3 (0 ~ 1.3cM), LG 7 (13~17.8 cM), LG8 (0~1.3cM), LG9 (3.4~7.3cM), and LG10 (40.8~41.7cM), where genes for several important traits may be present. Allele specific PCR primers (AS-PCR) were designed and tested with a cowpea breeding population. Out of the 57 SNP targeted using mismatch approach, amplification for 10 SNP were found to give robust AS-PCR, which is a good success rate for the marker development. Allele specific amplification was observed for at least one of the two alternative alleles at these SNP sites. In this study we found AS-PCR to be an efficient, cost effective and reliable way for SNP validation. Earlier studies in barley also revealed efficient validation of SNPs by allele specific PCR. 102 Engaging Smallholder Farmers | Tropical Legumes II Project
Strengthening capacity of national agricultural research systems scientists Degree-related and short time training activities were carried out during the first phase of TL II. Students from the five countries were trained or their training was supported (as in Mali and Niger below) by the project. The project trained two students from Mozambique at MSc level in plant breeding at Bunda College of Agriculture Malawi. The project paid fully for the students’ training in a different country than theirs. In addition, some technical staff received training in the field on screening for drought tolerance in crops. Farmers also participated in one day workshops where the protocol for PVS was discussed and agreed (Table 10). Training of graduate students in plant breeding Mali:- Siaka Dembele – Screening for virus resistance in cowpea Niger:- Abdou Souleymane – Screening cowpea for aphid resistance These two students are under the AGRA MSc program. Both are registered at the University of Ibadan and are conducting their research in cowpea breeding at IITA with funds from TL II. Nigeria: 1. Auwalu Umar – Genetics of duration of cooking time. This student is to complete his study in June 2011 2. Habibu Aliyu – Aphid resistance in cowpea. This student is to complete his study in August 2011. Mozambique:- Two students from Mozambique were trained in plant breeding at MSc level at Bunda College, Malawi. They are: 1. John Bulassi Kaunda MSc (Breeding) returned to IIAM working on cowpeas in Lichinga, Niassa Province 2. Henriques Victor Collial MSc (Breeding) returned to IIAM Nampula working on both Cowpea and Soybean. Tanzania:- One MSc. Student, Mr. Didas Kimaro completed his research project in September, 2010. All the university fees and direct costs for student, including funds for his research have been paid by the TL II project. Table 5-13: Number of farmers and technicians trained per country Country Number Mali 100 Niger 369 Nigeria 3,500 Mozambique 1,659 Tanzania 469 Total 6,097 5.2.2.15 Workshops Stakeholders meetings held each year at the Sub-regional level of WCA and ESA for cowpea and soybean. For WCA the meetings held in Niamey in 2008, Maradi in 2009 and Kano in 2010. All collaborators from the NARS, ADPs and NGOs such as SNV and Alheri Seeds in Niger were invited and participated actively in the meetings where activities in the previous year was reviewed and plans for coming season were fine tuned. There were also short duration (one day each) meetings with farmers’ groups where reports of experiences in the fields during previous cropping season were discussed. Farmers who wished to participate in the PVS were also identified at such meetings. Progress of Phase 1 103
