Genetic distances between a priori defined populations of tetraploid wheats.

Bread wheat (Triticum aestivum) is included for comparison. Distances are based on 29 nuSSRs. dCM: durum Central Mediterranean; dNEA: durum Northeast Africa; dNWA: durum Northwest Africa; dSEE: durum Southeast Europe; dSWA: durum Southwest Asia; dSWE: durum Southwest Europe.本数据集纳入普通小麦（Triticum aestivum）作为对照材料。遗传距离基于29个核简单序列重复（nuclear simple sequence repeats, nuSSRs）标记计算得到。其中：dCM代表硬粒小麦地中海中部种群（durum Central Mediterranean）；dNEA代表硬粒小麦东北非种群（durum Northeast Africa）；dNWA代表硬粒小麦西北非种群（durum Northwest Africa）；dSEE代表硬粒小麦东南欧种群（durum Southeast Europe）；dSWA代表硬粒小麦西南亚种群（durum Southwest Asia）；dSWE代表硬粒小麦西南欧种群（durum Southwest Europe）。
