| Research Abstract |
Carotenoids have healthy functionality. The high content of carotenoids in citrus fruit is an important breeding objective. The content of the carotenoid is different in each cultivar. However the dominant cultivars in Japnan originates in the ancestral cultivar of 14. Therefore, the number of allele is limited to 28. The purpose of this study is that the allele type of 28 is shown in eight carotenoid metabolic enzyme genes and three transcription factor candidate genes that control them, and the allele combination related to the high content of carotenoids is clarified.
Consequently, the sequences of 11 genes related to the content of the carotenoid was decided in the ancestral cultivar of 14. The allele type was decided by the SNP analysis.
