Ecotypes生态型 Ecotypes are genetically differentiated subspecies that are well adapted to a particular set of environmental conditions. >A genetically distinct geographic variety,population or race within species (or among closely related),which is adapted to specific environmental conditions. Typically,ecotypes exhibit phenotypic (differences (such as in morphology or physiology)stemming from environmental heterogeneity(异质性)and are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor
