- ... Seed dormancy, the main factor contributing to preharvest sprouting (PHS) resistance, is a complex trait and is strongly influenced by environmental growth conditions. In this study, three sets of single chromosome substitution lines, including 36 genotypes, in a durum wheat [ L. ssp. (Desf.) Husn.] background with donor chromosomes originating from three wild emmer [ L. ssp. (Körn. ex Asch. and G ...

- ... Previous studies have shown that there is considerable population structure in cultivated barley (L.), with the strongest structure corresponding to differences in row number and growth habit. U.S. barley breeding programs include six-row and two-row types and winter and spring types in all combinations. To facilitate mapping of complex traits in breeding germplasm, 1816 barley lines from 10 U.S. ...
