Anthracnose, caused by Colletotrichum spp., is one of the most common diseases affecting sweet pepper and chilli pepper production worldwide, especially in tropical and subtropical zones. This disease results in severe fruit damage both pre‐ and postharvest. The development of resistant cultivars is the most effective strategy for disease control, which requires knowing the genetic basis of resistance. In this study, we analysed the inheritance of resistance of Capsicum annuum to Colletotrichum scovillei at two fruit development stages. The ripe and unripe fruits were inoculated by conidia suspension, and anthracnose severity was evaluated for 8 days using a score scale. It was found that the inheritance of resistance has independent expression in ripe and unripe fruits. In both cases, two main genes are responsible for resistance with polygenic effects. Genetic control, with a quantitative aspect, is more affected by dominance than the additive effects, in both fruit development stages of C. annuum.

成熟和未成熟辣椒果实抗炭疽病（Colletotrichum scovillei）的遗传

炭疽病由炭疽病菌引起，是影响全球甜椒和辣椒生产的最常见病害之一，尤其是在热带和亚热带地区。这种病害会导致果实采前和采后严重受损。开发抗病品种是最有效的疾病控制策略，这需要了解抗病的遗传基础。在本研究中，我们分析了辣椒在两个果实发育阶段对炭疽病菌的抗性遗传。成熟和未成熟的果实通过分生孢子悬浮液接种，并使用评分量表评估炭疽病的严重程度8天。发现抗性的遗传在成熟和未成熟的果实中具有独立的表达。在这两种情况下，两个主要基因负责具有多基因效应的抗性。在 C. annuum 的两个果实发育阶段，从数量上讲，遗传控制受优势的影响比加和效应的影响更大。
