Abstract
Comparison of chickpea (Cicer arietinum L.) genotypes for morphological and biochemical attributes was done.
Morphological characters viz. Plant height, number of branches and number of leaves were recorded highest in
chilling tolerant genotypes at early stages of development (30 and 60 DAS) whereas at later stages (90 and 120
DAS) these characters were recorded highest in chilling sensitive genotypes. Pollen viability percentage at 5
and 10oC temperatures were recorded highest in chilling tolerant genotypes as compared to sensitive genotypes.
Biochemical characters viz. electrolyte leakage (%), total soluble sugars and total free amino acids were
recorded highest in chilling tolerant genotypes as compared to sensitive genotypes.
