Abstract

The root-knot nematode, Meloidogyne enterolobii, is an important pathogen of numerous crops, including the so-called pulses. Hence, it is necessary to identify genetic resistance, as it is the most efficient, cost-effective, and environmentally sound way to manage nematodes in the field. The objective of this study was to screen a Brazilian germplasm collection of pulse crops (peas, chickpeas, and lentils) comprising accessions from the Embrapa Germplasm Bank and commercial cultivars against M. enterolobii under glasshouse conditions. The experiment was conducted with 23 treatments (genotypes), i.e., 14 pea, six chickpea and one lentil genotype, and two tomato cultivars, ‘Rutgers’ (susceptible) and ‘Nemadoro’ (resistant). Each plant (replication) was inoculated with 5000 eggs and second-stage juveniles (J2) of M. enterolobii and evaluated 65 days after inoculation, considering the following variables: gall index, egg mass index, number of eggs per g of roots, and reproduction factor. The experiments were conducted at two independent time points (summer and autumn/winter). Results showed that all 23 plant genotypes were susceptible to the nematode, with pea genotype ‘Itapuã’ being intolerant to infection. Cultivation of pulse crops has been steadily increasing both in Brazil and worldwide. Our research findings make a valuable contribution to the ongoing efforts to identify genetic resistance to nematode pathogens that can significantly affect the productivity of these crops. By identifying and developing resistant genotypes, pulse crop yields can be safeguarded, and sustainable agricultural practices can be supported.

巴西豆类（豌豆、鹰嘴豆和扁豆）基因型对根结线虫 Meloidogyne enterolobii 的反应

根结线虫（Meloidogyne enterolobii）是许多作物（包括所谓的豆类）的重要病原体。因此，有必要确定遗传抗性，因为这是田间管理线虫最有效、最经济、最环保的方法。本研究的目的是在玻璃温室条件下筛选巴西豆类作物（豌豆、鹰嘴豆和扁豆）的种质资源，其中包括 Embrapa 种质资源库和商业栽培品种对肠线虫的抗性。实验采用 23 种处理（基因型），即 14 种豌豆、6 种鹰嘴豆和 1 种扁豆基因型，以及两种番茄栽培品种 "Rutgers"（易感）和 "Nemadoro"（抗性）。每株植物（重复）接种 5000 粒卵和肠孢霉第二期幼虫（J2），接种 65 天后进行评估，评估变量包括：虫瘿指数、卵块指数、每克根中的卵数和繁殖系数。实验在两个独立的时间点（夏季和秋冬季）进行。结果表明，所有 23 种植物基因型都易受线虫感染，其中豌豆基因型 "Itapuã "不耐受线虫感染。巴西和全世界的豆类作物种植面积都在稳步增长。线虫病原体会严重影响这些作物的产量，我们的研究成果为目前鉴定线虫病原体遗传抗性的工作做出了宝贵贡献。通过鉴定和开发抗性基因型，可以保障脉冲作物的产量，支持可持续农业实践。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
