Yield evaluation of fourteen populations of climbing bean (Phaseolus vulgaris L.) segregating lines with anthracnose (Colletotrichum lindemuthianum) resistance genes

Common bean is an important low cost and easy access protein source for the Andean region population. Fourteen ‘Bola roja’ and ‘Cargamanto’ climbing bean populations resulting from hybridizing six different regional varieties with anthracnose resistant genotype G2333, were evaluated under greenhouse conditions. With the aim of assessing yield of these hybrids, a completely randomized design was applied for the comparison of the following parameters: 100-seeed weight, number of grains per pod, and number of pods per plant. Te latter was found to be the most important yield indicator. Te study also allowed determining the best evaluated genotypes, which are currently still segregating. Terefore, it is recommended to continue developing line RC₁F₃.
