Morphologic diversity of Phenotypes in Peruvian Maca (L. peruvianum). Distribution of dried Maca hypocotyls in commercial crops of mixed phenotypes originating in Junin (sizes large & small) and Ancash (small size only) assessed on g/hypocotyl basis (with corresponding +/- SD) and number of differently-colored expressed as a percentage of the total counted hypocotyls in the mixed Maca crop (% - in italics)* and two reference values used for comparison only (not included in statistic evaluation)

Values with unlike lower case letters within the columns indicate an existence of differences in hypocotyls’ weight (g) between Yellow, Purple, Red and Black Peruvian Maca phenotypes at statistically significant level (P<0.05), while unlike Roman numbers within the rows (within each phenotype) indicate significant differences (at P<0.01) in weight (g) of dried hypocotyls obtained from Junin (Large and Small) and Ancash (Small only).
derived from 12 commercial sub-samples originating in Junin District, consisting of both Large (“A”) and Small size (“C”) hypocotyls (2008 crop);
derived from 12 commercial sub-samples originating in Junin District representing Small size (“C”) hypocotyls only - (2008 crop);
derived from collection of Maca in Ninacaca, Pasco District (2006 crop) cited in study by Gonzales et al (2006) (No percentage values given);
derived from 3 collections originating in Junin District - cited in previous study by Meissner et al. (2005, 2006). Percentages only, weight of individual hypocotyls was not determined at that time.
Average weight of hypocotyls (g) and Standard Error of Mean (+/- SEM);
