Abstract

In this experiment the recurrent selection method in two cotton (Gossypium hirsutum L. var. latifolium Hutch) cultivars for resistance to ramulose was utilized. In the 2nd selection cycle there was a significative increase in resistance level fo HR 102 cultivar. A considerable increase in resistance level of about 20.56% at the end of third cycle of recurrent: selection was observed. Therefore the improved population from HR 102 could be utilized in any breeding program to raise ramulose resistance in cotton.
