Abstract

                                The present study with special reference to "Northerns" cotton has as its aim an analysis of some economic characters of the cotton boll such as shedding interval, maturation period, seed and lint weights and lint length in relation to the flower- ing period and to the development of the flower on primary or second- ary fruiting branch. The cotton plant experiences a gradual rise in atmospheric temperature during the period of the development of its bolls and a very common observation is a general decrease in the values of some of the boll characters as the season advances (8, 17). It is also sought to present in this paper some aspects of variation of the cotton boll with reference to its position on the plant.
