Relationships between grain filling characteristics and grain yield and yield components in maize

This study was carried out to investigate the relationships among grain filling characteristics (duration and rate of grain filling), grain yield and yield components in twenty eight corn hybrids with different maturity. Highly significant correlations were observed between the effective grain filling period and days to silking, kernel weight. Highly positive correlation were detected between the rate of grain filling during the effective grain filling period and kernel weight, kernel width and kernel volume. Significant positive correlations were detected between total grain filling period and rate of grain filling of lower part of the ear, kernel weight and grain yield.
