The experiments were conducted during kharif 2003 and 2004 seasons
to analyze the genotypic variations in stomatal regulation and root traits and their
association with yield parameters in moth bean (Vigna aconitifolia Jacq.) under
water scarcity conditions of arid zone. Wide range of variations in total dry matter
(TDM), pod yield (PY) and seed yield (SY) were noticed among the 26 genotypes.
Our results suggest that genotypes with thick leaves (low SLA) exhibit more drought
tolerance by keeping their stomata open at lower relative water content (RWC)
in leaves. Significant relationship of specific leaf area (SLA) with both seed yield
(r2= 0.57) and relative water content (RWC) (r2= 0.49) suggested that low SLA
could be an important leaf trait for selecting moth bean genotypes for higher yield
under water-deficit conditions. The strong relationship of specific root weight (SRW,
root weight per unit root length) with TDM (r2= 0.73) and PY (i= 0.56) indicated
that selection of genotypes with extensive root system would enhance the yield
of moth bean under water scarcity conditions of arid zone. This study suggested
that SLA, a cost-effective and easily measurable leaf trait, and/or SRW are the
potential selection criteria to enhance the moth bean yield under rainfed conditions
of the arid zone.
