Evaluation of Cotton Germplasm for Drought Tolerance: I. Water-Use Efficiency

J.E. Quisenberry and B.L. McMichael


 
ABSTRACT

As part of a continuing effort to develop cotton germplasm with improved drought tolerance, greenhouse and field studies were conducted to evaluate the amount of genetic variation available in water-use efficiency. Water-use efficiency is the amount of biomass produced per unit of water used. Representative germplasm from both commercial varieties and the race collection were used. We found that the amount of genetic variation in this trait is about equal to that found in other more commonly measured quantitative traits.
