Genetic Dissection of Growth and Eco-Physiological Traits Associated with Altitudinal Adaptation in Sakhalin Fir ( Abies sachalinensis ) Based on QTL Mapping
(1) Background: The genetic basis of local adaptation in conifers remains poorly understood because of limited research evidence and the lack of suitable genetic materials. Sakhalin fir ( Abies sachalinensis ) is an ideal organism for elucidating the genetic basis of local adaptation because its alt...
