The red colour of pepper fruits is determined by the y+ dominant allele and the yellow colour by the y recessive allele. The capsanthin-capsorubin synthase (CCS) gene is activated specifically during the final stages of pepper fruit ripening. RFLP and specific-PCR polymorphisms derived from the CCS gene were analysed in a F2 progeny of a red by yellow-fruited cross. They cosegregated completely with fruit colour. Our results support the hypothesis that the yellow phenotype might result from a deletion of the CCS gene. These specific markers were integrated into the genetic map and will be useful for marker assisted plant breeding.
辣椒果实的红色由显性等位基因y+决定，黄色由隐性等位基因y决定。辣椒红素 - 辣椒玉红素合酶（CCS）基因在辣椒果实成熟的最后阶段被特异性激活。在一个红色果实与黄色果实杂交的F2后代中分析了源自CCS基因的限制性片段长度多态性（RFLP）和特异性聚合酶链反应（PCR）多态性。它们与果实颜色完全共分离。我们的结果支持这样的假设，即黄色表型可能是由于CCS基因的缺失导致的。这些特异性标记已整合到遗传图谱中，将有助于标记辅助植物育种。
