Abstract:

This paper summarizes the research progress home and abroad identification of indicators in the cotton drought-resistance from seven areas of that morphological index, growth and development indicators, output targets, physiological, biochemical, ecological indicators and integrated indicators. It describes the various aspects of cotton characters on each growth period and growth period of drought stress. The paper proposes the major identification of indicators and methods in the Cotton Drought-resistance. It has practical value on making cotton breeding strategies and drought-resistance farming cultivation in actual practices and achieving a bumper harvest of cotton drought-resistance.
