Abstract

Our rapidly changing climate has resulted in a variety of consequences, yet there are currently limited studies that directly link phenotypic variations with fitness effects. This study aims to investigate the transferability of useful genes between related species of Populus through hybridization by performing a cross between parental generations to directly connect stress tolerance genes and phenotype. Interestingly, admixed plants with higher percentages of P. balsamifera ancestry were more sensitive to heat and drought, suggesting that these genes may not be beneficial under stress conditions. Next steps involve conducting molecular work using PCR to determine if the plants of higher fitness inherited specific candidate genes from their parents.
