drought is a major constraint to its productivity. Breeding for drought
tolerance requires knowledge of the type and intensity of drought and
the various traits and mechanisms employed by the plant to overcome
the drought effects. The number of traits that are associated with
terminal drought tolerance is overwhelmingly large and needs to be
prioritized and ranked for their strength of contribution to drought
adaptation and to incorporate in breeding programs. Therefore, the
objectives of this study were to understand the relative value of
various putative traits that confer yield advantages under terminal
drought stress in chickpea, and the traits that are amenable for high
throughput and their association with molecular markers. Twelve
chickpea genotypes, selected for contrast in root and shoot strength,
field-based drought tolerance and canopy temperature differences
were grown in terminal drought stressed and optimally irrigated
environments. Root, shoot, soil water, physiological and analytical
yield components were measured at periodical intervals and these
related traits were associated with grain yield through correlations,
regressions and path analysis. Path coefficient analysis revealed that
root traits, RLD and RDW, were associated with grain yield and these
relations were explained well if the active soil water mining zone roots
were considered against yield. Roots of all the depths were associated
closely with the total soil water uptake of the plants except at the
surface and ultimate depths at any given stage.
