Abstract

The experimental material comprised of 50 genotypes of Gossypium arboreum was grown during Kharif 2021-22 under rainfed conditions at Research Area of Cotton Section, Department of Genetics and Plant Breeding, CCSHAU, Hisar with the objective to determine correlation coefficient and path analysis. Randomized block design was used with three replication and each genotype was grown in single row of 6 m length with a spacing of 67.5 × 30 cm. These genotypes were evaluated for eight morphological, six physiological and three biochemical traits. The correlation studies revealed that seed cotton yield per plant showed highly significant and positive correlation with plant height, number of bolls per plant, boll weight and number of seeds per boll and also, positive and significant correlation with crude protein content. Furthermore, Path analysis indicated that maximum value for direct effects were observed for number of bolls per plant followed by boll weight, relative water content, seed oil content, proline content, number of monopods per plant. Therefore, selection should be done on the basis of these studied traits for further enhancement of seed cotton yield in future cotton breeding programme.

Conclusion

Correlation and path analysis are effective statistical tools for plant breeders as these tools aid in identification of suitable traits to be used as selection criteria for improvement of yield of a crop. Correlation analysis indicated that simultaneous selection based on plant height, number of bolls per plant, boll weight and number of seeds per boll will aid in improvement of seed cotton yield since these traits had significant positive correlation with seed cotton yield per plant. Furthermore, path analysis revealed that number of bolls per plant had positive and high direct effect on seed cotton yield per plant. Therefore, direct selection for this trait will accelerate the improvement of yield in desi cotton.
