Strawberry (Fragaria×ananassa Duch.) is rich source of dietary antioxidants, minerals and nutrients.
Dietary antioxidants have been known as beneficial for enhancing the fitness, preventing certain diseases
and even mitigating the effects of ageing. The objectives of the present study were to determine
variability and inheritance of antioxidants, to identify antioxidant rich and productive genotypes, and
to suggest suitable breeding approaches. The genotypes, namely Ofra, Chandler, Festival and Camarosa
showed higher concentrations of dietary antioxidants and therefore could be useful in future breeding.
Results indicate that the effect of the genotypes on antioxidant contents is stronger than that of
the environment. The high heritability (>80%) and low genetic advance as percentage of mean (80%) and high genetic advance as percentage of mean
(>40%). Positive direct effect on fruit yield was highest for phenol content (0.609) which is also fairly close
to its correlation coefficient (0.765) indicating that a direct selection based on phenol content would be
most effective and that the phenol content could be used as a reliable biochemical marker to identify the
productive genotypes having higher amounts of dietary antioxidants. The information could also be used
for developing antioxidant rich cultivars, i.e. ‘Breeding Strawberry for High Antioxidants’.
