Abstract
The identification of self-incompatibility genotype (S-genotype) will be useful for selection of pollinizers and design of crossing in cultivar improvement of sand pear. This paper reported the identification of self-incompatibility genotypes of seven Chinese and two Japanese sand pear cultivars using PCR-RFLP analysis and S-RNase sequencing. The S-genotypes of these cultivars were determined as follows: Huali 1 S1S3, Shounan S1S3, XizilĂĽ S1S4, Qingxiang S3S7, Sanhua S2S7, Huangmi (Imamuranatsu) S1S6, Huali 2 S3S4, Baozhuli S7S33, Cangxixueli S5S15. S-RNase alleles (S1 to S9) in sand pear could be identified effectively by PCR-RFLP analysis.
