PRJDB5527 Molecular basis for adaptive traits underlying local adaptation in Abies sachalinensis Two parents (No.236 and No.336) were selected from progenies that are produced by crossing high-altitude trees (1100-1200m alt.) and low-altitude trees (530m). One parent (No.236) were selected from progeny that high-elevation tree A33 sired by the low-elevation pollen mixture C1. The other parent (No.336) selected from progeny that high-elevation tree A39 sired by the low-elevation pollen mixture C1. Reciprocal hybridization (No.236 x No.336 and No.336 x No.236) was conducted in 2011 and their progenies were used for QTL mapping of local adaptation along the altitudinal gradient in Abies sachalinensis.
