An experiment was conducted on correlation and path coefficient analysis for yield and yield
contributing characters in upland cotton with 63 genotypes of cotton for seventeen characters at
Regional Agricultural Research Station, Lam Farm, Guntur, Andhra Pradesh. The character
association analysis revealed that number of monopodia plant-1, number of bolls plant-1, boll weight,
relative chlorophyll content, 2.5% span length, bundle strength and lint yield plant-1 were found to
have significant positive association with seed cotton yield plant-1 at both phenotypic and genotypic
levels. The path analysis indicated that the number of bolls plant-1, boll weight (g), seed index,
2.5% span length (mm) and lint yield plant-1 (g) showed direct positive effects and significant
positive correlation with seed cotton yield plant-1 (g) revealing that due weightage 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 traits to get higher seed cotton yield plant-1.
Key words: Correlation, cotton, path analysis, seed cotton yield.
