Genetic improvement for protein content and some agronomic traits in a white maize population [electronic resource].

Includes reference

This study was carried out at Gemmeiza and Sids Experimental Stations, Agricultural Research Center (ARC), Egypt. During the two- successive seasons from 2011 and 2012. In 2011 summer season, at Gemmeiza Agricultural Research Station, the S1 recurrent selection procedure was applied in the new improved cycle (Co) in the white population (AED Pop.). One hundred and twenty one ears with enough seeds were selected and each was divided into two parts, the first one was assigned for evaluating all studied traits and protein analysis. The second part was kept as remnant S1 seeds for developing the second cycle for each population. In 2012 summer season, at Gemmeiza and Sids Research Stations, one evaluation trial was conducted. The trial was executed Randomize Complete Block Design (RCBD) with three replications. Data were recorded for grain yield its component and protein yield. Mean squares of the protein yield (kg/fed), yield components and agronomic characters were highly significant for all studied traits, indicating that the 121 S1 progenies of the original cycle (Co) for this population were different in such traits. Mean squares of genotype x location interaction were highly significant for all characters, indicating that the 121 S1 progenies were differed in their protein yield and the behavior of these progenies were significantly differed from location to another in this respect for this population. Genotypic and phenotypic variances of protein yield (kg/fed) of 121 S1 progenies were 2921.92 and 3050.52 at Gemmeiza and 5884.95 and 6403. 74 at Sids, respectively.
