^aA population of 94 F₂ plants derived from a cross between JP-36121 and Ibarakimame 7 was used for construction of a linkage map spanning 2864 cM.

^bA population of 225 RILs derived from a cross between Osuzu and Athow was used for construction of a linkage map spanning 2613 cM.

^cA population of 143 RILs derived from a cross between Ippon_sangoh and Fukuyutaka was used for construction of a linkage map spanning 2470 cM.

^dPolymorphic ratio = number of polymorphic marker loci/number of analysed marker loci.
