Abstract:

'Hanfu' Apple cultivar(Malus×domestica) and its parents were used in this research to study its self-compatibility and identify their S-genotypes. The pollination test in the field showed that the 'Hanfu' is self-compatible, and its female parent 'Dongguang' is also self-compatible, but its male parent 'Fuji' is self-sterile as known. The S-genotype of 'Hanfu' was identified as S1S9 by the PCR-based method. Also, the S-genotypes of all 'Dongguang' cultivars which are homonym were identified except the 'Toko' which came from Japanese and was named as 'Dongguang' in Chinese. The results showed the S-genotype of 'Dongguang' from Liaoning Research Institute of Pomology is S2S19, showing no relationship with 'Hanfu', and the S-Genotypes of 'Dongguang' cultivars from Shenyang Agricultural University, and Jilin Research Institute of Pomology contain S9 allele, suggesting they are probably the female parent of 'Hanfu'.

Key words: Apple, 'Hanfu', Self-fruitfulness, S-genotype, Identification
