Interpretive Summary: Increasing heat stress significantly affects crop quality traits, including seed nutritional content of chickpea (also called garbanzo beans). To evaluate the impact of heat stress on seed quality, eight chickpea lines were grown under normal and heat stress conditions. Many of the seed quality traits were impacted by heat stress, and the information in this paper will allow breeders to choose the lines that were least impacted, and to understand how nutritional content of chickpea seeds need to be tested to ensure they will be nutrition when grown by farmers in a hotter climate.

Technical Abstract: Increasing occurrences of episodic heat stress significantly affect crop quality traits, including those of chickpea (Cicer arietinum L.). To evaluate the impact of heat stress on seed quality, eight chickpea genotypes were cultivated under control (25/15°C) and heat stress (35/20°C) conditions. The genotypes exhibited notable genetic variation in seed carbon (C, %), protein (%), phosphorus (P, %), potassium (K, %), magnesium (Mg, %), sulfur (S, %), and manganese (Mn, ppm) concentrations under both conditions. However, no significant variation occurred for seed iron (Fe, ppm), zinc (Zn, ppm), and copper (Cu, ppm) concentrations under control conditions or seed Fe under heat stress conditions. The genotype (G) × temperature (T) interaction was significant for all traits except seed K. Correlation analysis revealed positive correlations between seed C and protein, seed Mg and P, and seed protein and Mg under control conditions. Under heat stress, significant correlations occurred between seed Mg and S and seed protein and P. In contrast, significant negative correlations occurred between seed Ca and K under control conditions and seed Ca and K and seed Fe and Cu under heat stress conditions. Heat stress adversely affected nutritional quality and seed yield traits, emphasizing the need for further research to develop heat-tolerant chickpea cultivars with improved seed nutritional traits.
