AN INVESTIGATION ON CORRELATION AND REGRESSION ANALYSIS FOR FIELD AND ITS COMPONENTS IN GOSSYPIUM HIRUSTUM L.

Abstract

Three cultivars of Gossypium hirustum L. viz. Qalandari, TH-1100, and TH-1174 were grown during summer 1985-86 to examine the association among seed cotton field and its contributing traits. The study indicated that plant height had positive correlation with branches and seed cotton yield/plant whereas branches /plant revealed high positive association with bolls/plant and significant positive correlation with seed cotton yield, but negative correlation with days to boll formation. Bolls/plant showed positive and highly significant correlation with seed cotton yield/plant. The seed cotton yield/plant had negative significant association with days to boll formation. Days to flowering showed positive and significant correlation with days to boll formation. However, other traits had positive or negative relation among them but not so pronounced. It is suggested that plant height, branches, bolls/plant and days to boll formation are desirable characters in selection criteria.
