Many farmers have shown keen interest in several lines including IT00K-1263, IT97K-1069-6 and<br />
IT16 because <strong>of</strong> their yield per<strong>for</strong>mance, drought tolerance, grain color and size. These lines are early<br />
maturing and dual purpose producing more leaves which farmers are able to pick and consume be<strong>for</strong>e<br />
pods are harvested. In 2011, three varieties: IT-16, IT00K-1263 and IT97K-1069-6 were released in<br />
Mozambique.<br />

G x E analysis<br />
The yield data obtained from the 16 improved breeding lines that were tested in all five countries<br />
were subjected to GGE biplot analysis. Data from Tanzania were not included in the final analysis<br />
due to some discrepancies in yield values. The results <strong>of</strong> the GGE biplot analysis showed the lines<br />
that per<strong>for</strong>med relatively well in some environments compared with others. It also identified locations<br />
best suited <strong>for</strong> cowpea production. According to the analysis, seven genotypes, namely IT97K-1069-6,<br />
IT89KD-288, IT98K-166-4, IT97K-819-118, IT96D-610, IT98K-491-4 and IT99K-216-24-2 were the<br />
most responsive to the environments. Following a comparison <strong>of</strong> genotypes with an ‘ideal’ one, it was<br />
observed that IT98K-128-3, IT98K-311-8-2 and IT98K-626 were most desirable as they were closest to<br />
the ideal.<br />
The best lines as identified by the analysis <strong>for</strong> certain locations were not necessarily the same as those<br />
selected by farmers at those locations. Other attributes than yield were taken into consideration while<br />
lines were being selected. It is interesting to note that farmers in Tanzania and Mozambique selected<br />
