Abstract

Path of productivity is an approach that helps in the identification of the traits that are responsible for the productivity of the top genotypes. The ten top potential-derived F1s and ten least potential-derived F1s were considered as two groups and their means for each character were expressed as per cent deviation from the overall mean of the derived hybrids. These per cent deviation values help in identifying the important yield contributing traits responsible for high productivity seen in top potential genotypes as well as low productivity seen in least potential genotypes. In the top potential genotypes, the yield-attributing traits showed a positive per cent deviation from the group mean and in the ten least potential genotypes the yield-attributing traits showed a negative per cent deviation from the group mean.

Conclusion

The deviation of positive or negative would reflect on the nature of genes ultimately contributing towards the yield. Two sets of genotypes differing in their paths to productivity can be used in hybridization to bring together the different genes responsible for higher yields that are present in them. Superior segregants can be isolated later from such a cross. With the comparison of both the top and bottom crosses, we may say that there is a modified path of productivity for the superiority and inferiority of genotypes.
