abstract: A study was undertaken to identify the morphophysiological
traits associated with water-logging tolerance in pigeonpea [Cajanus cajan L. (Millsp.)].The formation of
aerenchyma cells, lenticels, and adventitious roots in the
tolerant genotypes were found to be associated with waterlogging tolerance in pigeonpea. The tolerant genotypes,
namely, ICP 5028, ICPH 2431, ICPL 87119, ICPH 2740, ICPL
149, ICPL 20241, and MAL15, exhibited varying responses
to hypoxic conditions. Formation of aerenchymatous cells
was common in all the water-logging tolerant genotypes.
Besides this, five tolerant genotypes (ICP 5028, ICPH 2431,
ICPL 87119, ICPH 2740 and MAL 15) developed lenticels,
while ICPL 149 and ICPL 20241 formed prominent
adventitious roots. None of these traits was present in the
susceptible genotypes. These traits developed only when
exposed to water-logging stress and facilitated oxygen
supply from stem to roots helping in respiration of the
suffering plants. Potential breeding strategies to develop
pigeonpea genotypes with enhanced levels of waterlogging
tolerance are discussed.
