A set of 37 genotypes selected from a survey of over 200 diverse germplasms, for their diverse drought tolerance mechanisms, were analyzed in this study for root physiological traits that are indicative of different drought resistance mechanisms. The genotypes include controls such as the drought sensitive IR64 and Nipponbare, along with the drought resistant Nagina 22 (N22) and Bengal landraces to identify distinguishing phenotypic features of resistant accessions. Anatomical traits studied include total areas of the cross-sections of the stele, cortex, aerenchyma, cortical-cell, and xylem tissue; the number of aerenchyma, xylem vessels, cortical cell file number and size that together …
