Novel QTLs in an interspecific backcross Oryza sativa x Oryza glaberrima for resistance to iron toxicity in rice

This study aimed at mapping quantitative trait loci (QTLs) for resistance to iron toxicity

Abstract

Iron (Fe) toxicity is a major constraint in lowland rice. Because of its higher rusticity and adaptability to adverse soil conditions, the African rice Oryza glaberrima constitutes a new potential source of genes for rice improvement.

This study aimed at mapping quantitative trait loci (QTLs) for resistance to Fe toxicity. A set of 220 BC3DH lines derived from the backcross O. sativa (Caiapo)/O. glaberrima (MG12)//O. sativa (Caiapo) was tested in hydroponics in the presence or absence of Fe2+ (0 or 250 mg L−1).
