  • a Fruit shape category for each accession was visually defined (see “Materials and Methods” and Supplemental Table S1). Attributes included in LDA: fruit shape index, distal end protrusion, widest width position, the proximal end blockiness at 20% of the height from the top of the fruit, rectangular, distal angle at 20% along the boundaries from the tip of the fruit, and proximal eccentricity. A description of the attributes is given in Brewer et al. (2006) and Gonzalo et al. (2009).
