Research Abstract

Drought reduces faba bean yield in many parts of the world.
Therefore, it is necessary to develop drought-tolerant faba bean cultivars. Plant breeders need to screen for drought-tolerant germplasm using fast and reliable screening tools, e.g., chlorophyll absorbance, thermo-imaging camera system, and electrical root capacitance. A set of faba bean genotypes was used to screen for drought tolerance. Leaf temperature depression (LTD), measured with the thermo imaging system, was significantly correlated with both dry regrowth weight (r = 0.423), dry matter 1 (r = 0.629), and fresh regrowth weight (r = 0.573). Moreover, root capacitance (RC) was significantly correlated with fresh weight 1 (r = −0.516). Genotypes S062 and S252 were considered drought tolerant. These two lines can be used in breeding programs to develop drought-tolerant cultivars. On the other hand, RC and LTD could be used as non-destructive screening tools for drought tolerance.
