Selection of a Representative Core Collection from the Chilean Common Bean Germplasm

Race Chile is an important component of the genetic structure of the common bean (Phaseolus vulgaris L.). The germplasm bank of the Instituto de Investigaciones Agropecuarias INIA contains 1200 accessions distributed mainly into two Active Working Germplasm Banks at INIA La Platina (Santiago) and at...

The germplasm bank of the Instituto de Investigaciones Agropecuarias INIA contains 1200 accessions distributed mainly into two Active Working Germplasm Banks at INIA La Platina (Santiago) and at INIA Quilamapu (Chillán) and also the Germplasm Base Bank at INIA Intihuasi (La Serena).
