Results <strong>of</strong> selection within the fast track nursery were less successful in the program in Melkassa in the<br />
sense that no line convincingly out-yielded a local check, Nasir. This variety proved to be quite drought<br />
tolerant, likely due to its history <strong>of</strong> selection. First, it was originally selected in Honduras in a region<br />
that is subject to drought, <strong>and</strong> thus could have experienced drought pressure during its development.<br />
Secondly, a Mexican race Durango accession is among its parental lines, <strong>and</strong> race Durango has been<br />
a source <strong>of</strong> drought tolerance.<br />
On the other h<strong>and</strong>, recombinant inbred lines introduced as part <strong>of</strong> a PhD thesis proved to be quite<br />
successful for the identification <strong>of</strong> high yielding navy beans for Ethiopia’s export market, both in<br />
managed drought trials in which they out-yielded the check amply (data not shown), <strong>and</strong> in regional<br />
trials (Table 6-16), although in 2010 rainfall was plentiful <strong>and</strong> yield data do not reflect drought in this<br />
particular year. Selections 23 <strong>and</strong> 80 were especially stable, yielding 11% <strong>and</strong> 12% more than the elite<br />
check Awash-Melka across environments, <strong>and</strong> 29% <strong>and</strong> 19% better in the lowest yielding environment<br />
(Pawe). (Awash-Melka was distributed as an elite variety under Objective 8.) Disease data were taken at<br />
