Assessment of Genetic Variability Estimates of selected Traits in Irish Potato Mutants

Abstract

For an effective potato breeding strategy, knowledge of the genetic parameters of traits, such as heritabilities and genetic correlations are essential, hence the need to assess the genetic variability estimates of yield-related traits in Irish potato mutants. Results: It showed that the highest positive heritability percentage (H2) estimates in Mpya and Sherekea mutants were in plant height with 81.51% and 87.7% respectively.Conclusion: Tuber number exhibited high heritability estimates displaying that induced mutation was successful in the development of new potato genotypes which be used in future breeding programs.
