Abstract: The multiple ecological niche of one-species (variety) (MENOS) population is formed by one species (variety),but the ecological units have different temporal,spatial,nutritional,temperature,or water ecological niche.The formation of MENOS population is characterized by its specific object,one species (variety),multiple layer canopy,human being's active adjustment,specific niche breadth,and overlap and separation of ecological units.This paper analyzed the characteristics of the super high yield cotton population with dual ecological niche of one-species (variety) (DENOS).As for the yield components,MENOS has the characteristics of high yield canopy and different yield plants.

Key words: Multiple ecological niche of one-species (variety) (MENOS), Niche breadth, Niche overlap, Cotton
