ABSTRACT

 

The present study was conducted to assess the superior tropical strawberry genotypes in terms of their nutritional quality and shelf life. In this study, eight strawberry genotypes collected from different sources namely FA-006, FA-007, FA-008, FA-015, FA-016, FA-017, FA-022 and BARI Strawberry-1were selected. The study results implied that among eight strawberry genotypes, the maximum amount of reducing sugar (2.07g/100g) and non-reducing sugar (0.90g/100g) content were recorded in the genotype FA-017 and FA-008, respectively. The highest amount of ascorbic acid (29.45 mg/100g) and the highest amount of β-carotene (7.20 IU/100g) content were obtained from the genotype BARI Strawberry-1. The maximum amount of calcium (0.656 %), phosphorus (0.240 %) and potassium (1.580 %) content was recorded in the genotype FA-022 and the maximum sodium (0.166 mg) content was obtained from the genotype FA-007. Under room temperature, the highest shelf life (6.5 days) was recorded in the genotype FA-017. Regression analysis showed that total sugar content increased whereas β-carotene content decreased upon increasing storage duration. Collectively, our results provide a list of strawberry genotypes which could be released as promising varieties with higher nutrient content and storage capacity after large-scale trial.
