To this end, populations of doubled haploid (DH) lines derived by anther culture, and single seed descent (SSD) lines derived by recurrent selfing, from two wheat crosses were evaluated, and compared to each other and the parental lines, for variation for a range of agronomic characters. The results indicated that selection for fitness traits (biomass, grain yield, ear weight) had operated on the SSD populationCollection: AGRIS Collection
