李自交亲和性及S单倍型在后代中的分离对日本果树科学研究所新育成的品种“蜜蔷薇”（S B S g）进行了研究。5株蜜蔷薇自花授粉后平均坐果率为11.2%。这一结果证实了“蜂蜜罗莎”是自交亲和的。自交后代分离出S B S B b和S B S g两种S单倍型，表明S B -单倍型是自交亲和的主要原因。S-RNase的表达分析表明，S B -RNase基因在花柱中转录。因此，S-RNase基因的转录抑制与“蜜玫瑰”S B -单倍型的自交亲和性无关。
Self-compatibility and segregation for S-haplotype in progenies in Japanese plum (Prunus salicina Lindl.) cultivar 'Honey Rosa' (S b S g ), recently released from the National Institute of Fruit Tree Science, Japan, were investigated. The fruit set rate of five 'Honey Rosa' trees after self-pollination was 11.2% on average. This result confirmed that 'Honey Rosa' is self-compatible. The progenies of the self-pollination segregated into two S-haplotypes, S b S b and S b S g , suggesting that the S b -haplotype is responsible for self-compatibility. Expression analysis of S-RNase showed that the S b -RNase gene was transcribed in the style. Therefore, it appeared that inhibition of transcription of the S-RNase gene is not responsible for the self-compatibility in the S b -haplotype of 'Honey Rosa'.
