Phytic acid is considered as the major storage pool for phosphorus in the seeds. Present study was experimented on 60 chickpea genotypes for MIPS gene, antioxidant activity, mineral content and phytic acid content. PCR analysis successfully amplified 400 bp fragment of MIPS gene in chickpea. The average phytic acid content observed across all the genotypes was 59.27 mg/100 g. The mineral content assorted for Fe and Zn was 2.41–129.98 mg/100 g and 313.58–1,490.47 mg/100 g, respectively. Significant association of high phytic acid and its mole ratio to zinc was depicted. The relationship between phytic acid content and mineral bioavailability was strongest in Fe ( r = 0.448**) followed by Zn ( r = 0.959**). This suggest that phytic acid significantly reduce the mineral bioaccessibility. Cluster analysis revealed the distinctness among genotypes on the basis of phytic acid and antioxidant activity and grouped them into seven clusters. Cluster (a) contains low phytic acid genotypes while cluster (b) grouped most of the high phytic acid contenting genotypes. Practical applications Phytic acid chelates micronutrient which prevent their bioavailability. Objectives of plant breeding programs demand enhancement of micronutrient concentration, antioxidant levels with low levels of phytic acid. The present study identified chickpea genotype KWR‐108 with high Fe and Zn contents with average levels of phytic acid. This genotype show prospective food source for commercial applications and can be used as a parent for designing future breeding program.
