^aCDC, Chinese differential cultivar; JDC, Japanese differential cultivar
^bThe Pi genes in the CDCs were adopted from Kiyosawa and Ling (1984), Mackill and Bonman (1992), Rai et al. (2011), Hua et al. (2012), and Singh et al. (2015), and those in JDCs from Kiyosawa (1981), Imbe and Matsumoto (1985); and Hayashi et al. (1998). The additional resistance genes in the CDCs given by α, β, γ, δ, and ε those were predicted in the current study by comparison of resistance frequencies between CDCs and JDCs carrying the same Pi genes
^cThe bold-faced ones were recognized as the higher resistance cultivar
