“…Negative associations were existed between sugar content and starch content; protein content and starch content; soluble solid concentration and protein content. This kind of associations were also observed by Dudley and Lambert (1992); Ha (1999), Kumari et al (2006). Many authors stated that soluble solid concentration has been utilised as a rapid, pre-harvest method to determine fresh sweet corn sugar content (Kleinhenz, 2003;Zhu et al, 1992).…”

The objective of this study was to determine genetic variability, heritability, genetic advance, genotypic and phenotypic correlations of yield, yield components and kernel quality traits in seven sweet corn varieties. The present research was conducted during 2009 and 2010 growing season in Eskisehir, midwestern Turkey. The trials were set up in randomised complete block design with four replications. Analysis of variance observed highly significant differences for all the examined traits in both years. Sugar content, soluble solid concentration and number of leaves per plant revealed the highest genotypic and phenotypic coefficient of variation values. The high heritability estimates coupled with high genetic advance for sugar content, soluble solid concentration and starch content. Positive correlations were revealed between yield (husked, dehusked and fresh kernel) and yield components except plant height and 1000 seed weight. Negative correlations were found between kernel quality and yield and yield related traits. It can be concluded that, husked ear weight and dehusked ear weight could be used as the main criteria for yield improvement. It should be unfeasible to develop sweet corn varieties with satisfactory yield potential and improved kernel quality for the different sweet corn markets.

“…After maturity, the 3 plants were harvested and their ears were naturally dried (Yang et al, 2012). Grain protein and oil content was measured for grain samples mixed within each plot by using a MATRIX-1 NIR spectroscope (Bruker Corporation, Germany) according to methods described by Dudley and Lambert (1992).…”

“…Using traditional quantitative genetic and statistical models, Dudley and Lambert (1992) revealed that the grain protein and oil content in maize was controlled by multiple genes with small individual and additive effects (Dudley et al, 1977). Miller and Brimhall (1951) reported that the total grain oil content was not related to the total grain protein content and was instead strongly positively related with grain protein content in the germ.…”

“…Melchinger et al (1986) reported that dominance effects were greater than additive effects for grain yield in maize. It was previously shown that oil content was under the control of additive gene actions (Dudley, 1977;Hussain et al, 2015). Our results were in consistence with previous studies.…”

This study was conducted to analyze the genetic effects for grain yield and some important kernel quality traits in maize. Eight parental lines and their six hybrids were used as plant material. Field experiments to evaluate plant material were carried out in two locations (Çanakkale and Bursa) in 2013. The observed traits were single plant yield, protein content and oil content. Additive, dominance and additive × additive models were utilized to analyze the data. Variance component estimations showed that single plant yield was under the control of dominance type gene action; while protein and oil content were controlled by additive type gene action. High values (> 60 %) of broad (H 2 ) and narrow sense (h 2 ) heritabilities were observed for protein and oil content. The mean of F 1 generation for single plant yield and oil content were higher than the mean of F 2 generation for these traits. Most of hybrids had positive mid parent heterosis (Hmp) and better parent heterosis (Hbp) for single plant yield, while they had negative heterosis values for protein content. Except for one cross (A680×IHO), all of crosses had positive Hmp values for oil content.
