Abstract


The move towards fruit with high concentration of specific nutritional components will help the breeders to select appropriate genotypes which can be used as key drivers in nutritional breeding. Consequently, the present study illustrated that, wide variation exists in the major nutraceuticals of mango which provides opportunities for genetic gain through selection or hybridization. The study showed wider genetic variability among the genotypes for biochemical components. Genotypes Amrapli, Alphonso, Langra and Aminkhurd are good source of phenols, carotenoids and antioxidants. Total phenols were indicated as the parameter under the control of additive gene which can be considered for further improvement through selection and it is also having a significant positive correlation with total antioxidants and total flavonoids. The a* and b* value of colour can be considered as a direct selection criterion for carotenoids rich genotypes. Thus, the selection may be possible for these traits or can be used as potential parents in hybridization programme for developing nutritionally rich genotypes in mango.
