From: Wheat grain width: a clue for re-exploring visual indicators of grain weight
The correlations among Major and Minor (representatives of grain length and width, respectively) and other basic shape factors, and also superior synthetized weight indicators. Major and Minor are the largest and shortest axes of the best ellipse fitted on each grain. Unit of all dimensions is pixel (the enhanced-resolution images of 19,596 grains sampled from all monocultures of early- to middle ripening cultivars grown during two seasons under well- and deficit-irrigation were used).
