摘要:

梨轮纹病是由葡萄座腔菌属(Botryosphaeria)真菌引起的梨主要病害之一,主要危害梨叶片、枝干和果实,严重影响梨的产量和品质,给产业造成重大经济损失。本研究通过离体叶片接种法,采用三个不同地区来源的菌株,对2025年4个梨杂交组合的519株F1代和15个梨品种叶片进行接种,采集了接种后3、5、7、9天的病斑直径数据,并根据抗性分级标准,评价了各F1代的抗性水平。结果显示,所有杂交组合后代抗感分离明显。本数据集将为研究梨轮纹病抗性遗传规律、相关分子标记筛选、发掘抗病相关基因等提供基础支撑,并为杂交亲本选配及抗病品种培育奠定基础。

Abstract:

Pear ring rot is one of the main pear diseases caused by Botryosphaeria fungi, which mainly harms pear leaves, branches, and fruits, seriously affecting pear yield and quality, and causing significant economic losses to the industry. This study used an in vitro leaf inoculation method to inoculate 519 F1 generation and 15 pear varieties of 4 pear hybrid combinations in 2025 with strains from three different regions. Data on lesion diameter were collected at 3, 5, 7, and 9 days after inoculation, and the resistance level of each F1 generation was evaluated according to the resistance grading standard. The results showed that the offspring of all hybrid combinations exhibited significant separation of resistance and susceptibility. This dataset will provide basic support for studying the genetic laws of pear ring rot disease resistance, screening related molecular markers, discovering disease-resistant genes, and laying the foundation for hybrid parent selection and disease-resistant variety cultivation.
