Physiological traits in relation to yield improvement in chickpea (Cicer arietinum L.) under depleting soil moisture environment

Published on

The chickpea genotypes along with F4 progeny lines
differing in their behavior towards drought were evaluated
for seed yield, yield attributes and physiological traits.
Drought decreased the leaf water potential, leaf osmotic
potential and relative water content in both parents and
progeny lines. The parent RSG 931 had more plant water
status as compared to HC 1 under drought condition. The
progeny lines G11, G10, G 04 and G 05 showed the similar
results. Leaf water potential, osmotic potential and RWC
had a significant association with seed yield (r = 0.86, 0.95
and 0.92, respectively). The seed yield decreased in drought
stress condition but decrease in yield of RSG 931 (19.27%)
was less than HC 1 (37.32%). The parent RSG 931 and the
progeny lines G11, G10, G 04 and G 05 had better plant
water status, CTD and photochemical efficiency and these
traits were directly associated with seed yield.
