SNP Markers Associated with Duration of Wheat Phenological Stages
Common wheat SNP markers identified in whole-genome association and QTL analysis linked with heading, flowering, and maturity times
This page summarizes the results obtained in our lab
The heading time is defined at the moment when 70% of the plants in the plot had emerged with the ear from the tube by one-half, and it was calculated as the number of days from seedling to heading (corresponding to stage GS55). The phenological stages were evaluated following the Zadoks classification (Zadoks, Chang & Konzak, 1974).

The maturity was determined by hard grains, yellowing, and drying of the ears and stems (corresponding to stage GS92). The phenological stages were evaluated following the Zadoks classification (Zadoks, Chang & Konzak, 1974).
