Abstract

                                The variation in the characters of cotton bolls picked at different parts of the season is a phenomenon familiar to cotton breeders. A gradual and pronounced decline in the values of these characters with the advance of the season is also a common experience. It often happens that seed material obtained from a portion of the picking period is used to raise the subsequent year's crop. A knowledge, therefore, of the influence of these parental variations on the characters of the progeny will be useful, particularly in breeding work on Cotton. Some aspects of this study are presented in this paper.
