Abstract

This study was carried out to determine relationships between physiological characteristics and yield of some maize varieties. The research was laid out as randomized complete block design with four replications in 2015 maize growing season. Six grain maize varieties which have different properties (PR31D24, Kalipso, 70MAY82, Suerto, P1921, DKC6724) were used as material. According to the obtained results, there were significant differences among varieties in terms of pre-flowering, flowering, post-flowering period’s chlorophyll contents (SPAD readings), leaf area index (LAI) and stomatal conductance. The P1921 variety had highest yield by 15181.0 kg ha-1. The correlation analysis showed that there were significant and positive correlations among grain yield and flowering period’s chlorophyll content. It was determined that there were interrelations between physiological and morphological parameters and these interrelations affects grain yield; in addition, the results indicated that chlorophyll content can be used as selection criteria in maize breeding programs.
