We investigated S-RNase genotypes of 21 wild apples with Neville Corpman, and King of Tompkins 1, 2 and 3 by the PCR-digestion method. M. sylvestris 392390 (T1-2-66) did not contain any known S-RNase allele, and seemed to be useful as a pollinizer. Thirteen individuals (M. baccata (S1-7-15), M. fusca, M. fusca F 50 (T1-16-51), M. orientalis (W1- 11-13), M. pumila Mill, M. pumila Pendula var. elise rathka, M. prunifolia USSR 18, M. prunifolia USSR 24, M. prunifolia USSR P, M. sieversii, M. sieversii (W1-10-49), M. sieversii sdl.2250 and M. sylvestris) contained an unidentified S-RNase allele with a known allele. Although M. baccata 4433 (79091) contained two known alleles, the S16a does not frequently occur in domestic Japanese cultivars. These wild apples also could be useful as pollinizers of cultivars in Japan, except for cultivars having an identical S-RNase allele. We have selected M. baccata 4433 (79091) as a pollinizer for the cultivar ‘Fuji’.

We isolated and confirmed two S-RNases, denoted as mpS1 and mpS2, from apple rootstock 'Marubakaido' (Malus prunifolia Borkh. Var. ringo Asami). These S-RNases contained and conserved five cysteine residues and two histidine residues, which are essential for RNase activity. The mpS1 showed high similarity to S5 (99.1%) of Malus spectabilis, whereas the mpS2 showed 99.5% nucleotide sequence similarity to S26 of (Malus ${\times}$ domestica) and 99.6% to S35 of (Malus sieversii) when compared with reported S-RNases. In amino acid sequences, the mpS1-RNase was almost similar to the S5-RNase of Malus spectabilis, and the mpS2-RNase was similar to the S35 of Malus sieversii, with only one bp being different from the S26-RNase of Malus ${\times}$ domestica. The 57 S-RNases of Malus species were renamed and rearranged containing the new S-RNases, as mprpS35 (mpS2) and mprpS57 (mpS1), for determining S-genotypes and identifying new alleles from apple species (Malus spp.).
