a AAFC, indoor controlled conditions at Agriculture and Agri-Food Canada; VES, natural outdoor conditions at Valcartier Experimental Station.

b P, first mapping population (cross C96-1-2856); D, second mapping population (cross C94-1-2516).

c corresponds to the range of bud phenology stages explained by each principal component (indeed, PCA were performed from means of stages of three blocks for each environmental condition).
