Abstract

An experiment was conducted to study the correlation and path analysis of fifteen cashew genotypes in DCR, Puttur. Results indicated that in correlation studies nut yield per tree has shown highly significant positive correlation with apple yield per tree and the traits viz., sex ratio and number of nuts per panicle had significant positive correlation with nut yield per tree. Path coefficient analysis revealed that the traits, canopy spread, sex ratio, nut weight and apple yield per tree showed direct positive effect on nut yield per tree indicating the utilization of these parameters in crop improvement programme to evolve high yielding cashew varieties.

Correlation, Path analysis, Cashew, Genotype

Conclusion

Based on the above results it can be concluded that nut yield can be improved by selecting accessions having more sex ratio, number of nuts per panicle and apple yield per tree. Because these characters had shown significant positive correlation with the nut yield per tree. Results of the phenotypic path analysis revealed that, out of eleven characters studied, four characters showed positive and direct effect on nut yield per tree at phenotypic level viz., canopy spread, sex ratio, nut weight and apple yield per tree.
