Phenotypic predictors of dent maize grain quality based on different genetics and management practices

Sammanfattning

Attempts to determine phenotypic predictors to identify high quality maize grain for different uses are noteworthy. This study aimed to assess the relationships among maize grain quality and some phenotypic characteristics of dent maize cultivars in response to various irrigation regimes (6-day and 12-day intervals), planting dates (20 June and 21 July), and nitrogen rates (0 and 184 kg ha(-1)), in a two-year experiment. Principal component analysis suggested that grain yield, hundred-grain weight and stem biomass were highly correlated with starch, oil and most fatty acid concentration variables. Grains per ear was the only variable correlated with amylose, protein and amino acids. Using regression tree analysis, stover yield (R-2 = 0.47, P
