Fig. 1From: Morphological characterization and genetic diversity analysis of Tunisian durum wheat (Triticum turgidum var. durum) accessionsPrincipal component analysis plot depicting 11 durum wheat landraces within 304 Tunisian accessions using 12 morphological traits under GenAlEx (version 6.501) [25]; (a) Projection of the 12 variables on the PCA plot axes. SS: spike shape, SL: spike length, AL: awn length, SC: spike color, NS: number of spikelets/spike, GlC: glume color, GN: number of grains/spikelet, GSp: grain shape, GSz: grain size, GC: grain color, AC: awn color, SD: spike density; (b) Projection of the 304 accessions on the PCA plot axes. Accessions were color-coded according to their landraces nomenclature, as identified with the morphological characterizationBack to article page
