Abstract

A non-destructive method has been developed to select common bean (Phaseolus vulgaris L.) plants whose growth is less effected at a suboptimal temperature. Shoot weight was determined at a suboptimal (14°C) and optimal temperature (20°C), 38 days after sowing and accessions identified with a significantly lower than average weight reduction at 14°C compared to their weight at 20°C. Weight of primary leaves and of the shoot was correlated with seed weight at both temperatures, but no correlation was found between shoot weight reduction at 14°C and seed weight.
