Evaluation of several selection procedures for predicting yield performance of progenies in two populations of cotton (Gossypium barbadense L.)

Average, combined and specific indices involving lint yield and its components “seeds per boll” and “lint per seed” were computed for two populations of cotton (Gossypium barbadense) evaluated in two seasons. All indices were constructed to maximize advance in “lint yield”. Indices were evaluated as to their usefulness in identifying high yielding genotypes. Within the limits of this experiment it was shown that:

1. 1.
   Specific indices were superior to yield as criteria for selection in both predicted and actual gains.
