Distribution pattern of the gene density and the number of QTLs and MQTLs on the rice genome. The outermost circle represents the chromosomes position on the rice genome in Mb. The black head arrow indicates the centromeric position of the chromosome. The second circle with red color outlines the gene density on the rice genome. The third and fourth inner circles with green and blue colors display the number of QTLs and MQTLs, respectively.
