ABSTRACT
Drought
stress is one of the major abiotic stresses in agriculture worldwide. The study
was carried out to investigate the effect of drought stress on carbohydrate
content in drought tolerant and susceptible chickpea genotypes. A field
experiment was carried out at Student’s Instructional Farm in a randomized block design with three
replications and in the laboratory of Department of Biochemistry
during Rabi season of 2013-14 and
2014-15. The tolerant variety accumulated more
carbohydrate content than the sensitive one. Results showed
that carbohydrate content ranged between 61.51 to 66.64 per cent in the year
2013-14 and 61.44 to 66.53 per cent in the year 2014-15. First year experiment
recorded highest carbohydrate content in tolerant genotype K 850 (66.64%) and
the lowest value were recorded in susceptible genotype PUSA 372 (61.51 %). In
the second year experiment maximum carbohydrate content was recorded in K 850
(66.53%) whereas, the lowest value was noticed in PUSA 372 (61.44 %). Analysis
of the data indicates that genotypes diferred significant with regard to
carbohydrate content in both of the years. So, carbohydrate in stress condition can be used as markers for selection
of drought tolerant genotypes.
