Abstract

Verticillium wilt caused by Verticillium dahliae is one of the most devastating diseases of cotton worldwide but little is known about resistance of cotton to V. dahliae for phenotypic quantifying. The aim of the current study was to phenotypically characterize resistance of 18 advanced cotton lines to defoliating pathotype (Vd-34) of V. dahliae. Experiments were set up in a greenhouse in two consecutive years. Phenotyping of plant response to V. dahliae was quantified by assessing five agronomic traits (defoliation rate, plant height, root weight, stem diameter, biomass) and internal vascular discoloration. Reaction types were established using area under the disease progress curve (AUDPC). The defoliating pathotype Vd-34 induced significant (P ˂ 0.01) reductions in all the examined agrononic traits. Overall reductions in root weight, defoliation rate, plant height, biomass and stem diameter were detected as 42.33, 34.13, 33.56, 32.31 and 26.63%, respectively. Based on the AUDPC values, of the 18 advanced cotton lines, AntV-17, AntV-19 and AntV-20 were detected as moderately resistant to the defoliating pathotype of V. dahliae, while the others showed moderately susceptible, susceptible and very susceptible reactions. The disease quantifying parameters (AUDPC, rAUDPC and vascular disease score) significantly (P ˂ 0.01) and positively correlated with the reductions in the examined agronomic traits. To our knowledge, this is the first detailed phenotyping for resistance to defoliating pathotype of V. dahliae in cotton and reveals new knowledge to quantify cotton resistance to V. dahliae.

先进棉花品系抗大丽轮枝菌落叶病型的表型特征

由大丽轮枝菌（Verticillium dahliae）引起的轮枝枯萎病是全球棉花最具毁灭性的病害之一，但人们对棉花对大丽轮枝菌抗性的表型量化知之甚少。本研究旨在从表型上描述 18 个先进棉花品系对大丽轮枝菌脱叶病型（Vd-34）的抗性。实验连续两年在温室中进行。通过评估五个农艺性状（落叶率、株高、根重、茎直径、生物量）和内部维管变色，对植物对大丽蚜的反应进行表型量化。通过病害进程曲线下面积（AUDPC）确定反应类型。脱叶病原型 Vd-34 导致所有受检农艺性状显著降低（P ˂ 0.01）。根重、落叶率、株高、生物量和茎径的总体下降率分别为 42.33%、34.13%、33.56%、32.31% 和 26.63%。根据 AUDPC 值，在 18 个先进棉花品系中，AntV-17、AntV-19 和 AntV-20 被检测出对大丽花落叶病病原型具有中度抗性，而其他品系则表现出中度感病、感病和极感病反应。病害量化参数（AUDPC、rAUDPC 和维管束病害评分）与所考察的农艺性状的减少呈显著正相关（P ˂ 0.01）。据我们所知，这是首次对棉花对大丽花病毒（V. dahliae）落叶病病原型的抗性进行详细的表型分析，揭示了量化棉花对大丽花病毒（V. dahliae）抗性的新知识。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
