Conclusion
Wide genetic diversity in the 7 mineral elements in 20 brown
rice accessions was discovered in 2 years. These mineral elements
were affected by genotype as well as environment. The effects of
genotype environment interaction should also be considered in
different environments. Moreover, we discovered 17 QTLs involved
in the accumulation of 5 mineral elements. This study provided
new information on the understanding of the contributions of
the genotype and environment interaction effects to the complex
traits such as mineral contents in the brown rice. The results will
also be useful for developing rice varieties high in the mineral
nutrients in the grains by molecular breeding.
