Most of the QTL for germination sensu stricto clustered on chromosome 1DS in the region Xgwm1291–Xgwm337. Twenty QTL were mapped to chromosomes 1D, 2D, 4D, 5D, and 7D. Seedling growth was assessed both under non-stressed and under osmotic stress conditions. Seed longevity was evaluated from the relative trait values. To quantify seed vigour, the same traits were measured from batches of seed exposed for 72 h at 43☌ and high (ca. Seed germination (capacity, timing, rate and synchronicity) was characterized by a standard germination test, based either on the 1 mm root protrusion (germination sensu stricto) or the development of normal seedlings. Quantitative trait loci (QTL) controlling germination, seed vigour and longevity, and early seedling growth were identified using a set of common wheat lines carrying known D genome introgression segments.
