GENETIC ANALYSIS OF CULTIVATED PHASEOLUS VULGARIS L. CORE COLLECTION OF INIFAP-MEXICO

摘要

Common bean (Phaseolus vulgaris L.) is a basic food for Mexican people and is cultivated up two million hectares annually. Despite the importance of common beans, the broad genetic diversity has been lost due to man and environment impacts (3). The genetic diversity analysis can verify the bean genetic changes to improve conservation strategies (6, 7, 8). Classical criteria to quantify genetic variability are based on either expected heterozygosity or genetic diversity index calculations (11). Molecular marker methodologies have been applied to analyze genetic variability because they are neutral and can be used to analyze evolution and conservation of new morphotypes in crops (7, 8). Molecular markers can also be used to determine historical and geographical relationships among plant species and/or populations (1).
