Chlorophyll and Canopy Temperature Depression as a Tool to Monitor Physiological Status of Cicer Arietinum L. Genotypes under Normal and Heat Stress Environment

Environmental mortification and mounting temperature are investigated to be the prime cause of the catastrophe of agriculture. Chickpea is a cool-season crop that is badly damaged by heat stress. In the present research, IR and SPAD-502 plus meters are used to evaluation of chickpea germplasm in a heat stress environment before the stress and strain symptoms were visible. Experiments performed November (normal-sown) and December (heat-sown) month of the year 2019 at the Department of Botany, Campus C. C. S. University, Meerut Uttar Pradesh. Tolerant genotypes (JG 11, JAKI 9218) which is Desi shows higher canopy temperature depression and chlorophyll content while the susceptible genotype i.e., JGK 2 which is Kabuli shown lower canopy temperature depression and chlorophyll values. Tolerant genotypes showed lower % decline values of grain yield plant−1 (5.0 and 7.0% decline) as compared to susceptible genotype which has the higher % decline value i.e., 41%. Results have concluded that chlorophyll content and leaf canopy temperature depression are sophisticated tools for the early selection of heat-tolerant chickpea genotypes.
