COMMON BEAN LINE SELECTION FOR DROUGHT RESISTANCE

摘要

Common bean (Phaseolus vulgaris L.) is a legume grown worldwide for its economic, social importance and high nutritional value. However, abiotic factors, such as drought, can compromise the development of the crop and reduce its production. The effects of water deficit have been studied, supporting selection of lines more adapted to this adverse condition. Thus, the determination of drought resistance parameters is essential to ensure efficiency in the process of selecting potential genotypes for drought resistance. This work aimed to evaluate 121 common bean lines collected in Brazil in field conditions, and to select bean lines with drought resistance.
