Geographic differences and variation of functional components of brown rice in 690 mini-core collections from global germplasms.

ABSTRACT:

Objective

To understand the geographic differences and variations in the functional components of brown rice cores collected from global rice germplasms.

Methods

Four functional components, γ-aminobutyric acid (GABA), resistant starch (RS), total flavonoids, and alkaloids, in brown rice from 690 mini-core collections from 31 countries from five continents and the International Rice Research Institute, were analyzed using a spectrophotometry colorimetric method, and the results were statistically validated.

Conclusion

The highest average amounts of functional components were obtained in Asian germplasms, except for GABA, and total flavonoids were highest in brown rice from Europe and Oceania, followed by Asia. The highest coefficient of variation for GABA was observed
