Abstract

To investigate the genetic properties of some physiological and agronomical characters in maize, a six-parent diallel cross, excluding reciprocals, was grown in a randomized complete block design with three replications under two different environments (irrigated and rainfed) in the Research Station of Dezful, Iran. High narrow-sense heritability estimates were observed for relative water loss, excised leaf water retention, number of seed per plant, seed weight and number of ear per plant. Additive gene action was found to be predominant for relative water loss, excised leaf water retention, seed weight and number of ear per plant. The results of combining ability analysis revealed that the genotype k1515 was the best general combiner for improvement of osmoregulation, and k18 × k1264 and k19 × k1264 were the best specific combination for improvement of osmotic adjustment and stress tolerance index.
