While the fast track entries were recovered <strong>and</strong> cycled through the evaluation scheme, lines selected<br />
previously under a parallel project were advanced <strong>and</strong> are at the point <strong>of</strong> release. Across four sites including<br />
two on-farm sites in the north <strong>of</strong> Malawi (CHS <strong>and</strong> BOK), small red seeded lines out-yielded the local check<br />
CAL 143 by as much as 50% (Table 6-17). Although not the most preferred type in Malawi, small red beans<br />
do appear in local mixtures. The national program is considering the release <strong>of</strong> SER 83 <strong>and</strong> SER 45.<br />

A total <strong>of</strong> 1007 lines were first evaluated for adaptation <strong>and</strong> photosensitive response under irrigation<br />
at Harare Research Station in August 2008. Not all lines were adapted, <strong>and</strong> those that excelled were<br />
planted again in two sets, one under water stress <strong>and</strong> the other under irrigation in February 2009 at<br />
Gwebi Variety Testing Centre. However, the crop in the irrigated field was partly grazed by antelopes<br />
during the trifoliate stage. Drought in the water stress treatment was not severe as expected since some<br />
unexpected rains were received during the early podding stage, but 200 lines were selected under these<br />
drought conditions.<br />
