A
field experiment was conducted with eight fenugreek genotypes comprised of
advanced lines and released varieties viz. UM-71, UM-68, UM-78, UM-80,
UM-90, Rmt-305, Rmt-354 and Rmt-143 to assess the genetic variability under
drought condition. Moisture stress was created by withholding irrigation in one
set of genotypes at active growth stages while other sets were given normal
irrigation. Different physiological, biochemical and antioxidant parameters,
yield and yield contributing parameters were recorded under optimal and limited
irrigation at flowering and pod filling stages. The result showed that
different physiological parameters such as relative water content (RWC),
chlorophyll content, carotenoids and membrane stability index decreased while
biochemical parameters like proline, glycine betaine content and antioxidant
enzymes like superoxide dismutase (SOD) and catalase increased under drought
condition.
