Description Chickpea is a cheap source of protein and micronutrients to the poor and vegetarian population living in south-
Asia and sub-Saharan Africa. Due to changes in climatic conditions and cropping systems, the crop is being
exposed to severe drought and heat stress during its reproductive period, which leads to significant yield losses
and fluctuations in grain nutrient accumulation. The study was conducted with 140 diverse genotypes under nonstress,
drought, and heat stress conditions to estimate their effects on grain nutrient (protein, Fe and Zn) contents
and identify the marker-trait associations. Analysis of variance revealed highly significant differences among
genotypes for nutrient content under respective planting conditions. The seed yield was negatively associated
with the grain Fe (r =
