Correlation and path coefficient analysis for yield and yield contributing characters in American cotton with 56 genotypes for 14 traits was studied during Kharif, 2017-18. The character association analysis revealed that plant height (cm), number of monopodia plant-1 , number of sympodia plant-1 , number of bolls plant-1 , boll weight (g), seed index (g), lint index (g), micronaire value (10-6 g/inch) and uniformity ratio were found to have significant positive association with seed cotton yield plant-1 at genotypic level. The path analysis indicated that the plant height (cm), number of monopodia plant-1 , number of bolls plant-1 , boll weight (g), seed index (g) and micronaire value (10-6 g/inch) showed direct positive effects and significant positive correlation with seed cotton yield plant-1 (g). It is revealed that priority should be given in selection process with more number of bolls plant-1 and more boll weight and there should be economic balance among these characters to get higher seed cotton yield plant-1 .
