Fig. 2From: Linkage disequilibrium mapping for grain Fe and Zn enhancing QTLs useful for nutrient dense rice breedingGenotype-by-trait biplot graph showing 102 genotypes in two main principal components for three traits. Fe: grain iron content; Zn: grain zinc content; yld: grain yield (kg/ha); PN: panicle number; DFF: days to 50% flowering. The dot numbers in the figure represent the serial number of the genotypes enlisted in Table 1Back to article page
