Abstract

The effects of the seed gall nematode ‘Anguina tritici’ (Steinbuch, 1799) on the agronomic characteristics of some bread wheat cultivars were investigated at the Trakya Agricultural Research Institute, Türkiye. An experiment was carried out in two different locations in Edirne in the 2019–2020 growing season. A total of 19 winter bread wheat cultivars were evaluated to assess infected grain number, healthy grain number, infected grain rate and yield. According to the results of the combined variance analysis, a statistically significant difference (p ≤ .01) was found in terms of yield from the application of inoculum. Compared to the control in wheat cultivars, there was a 52.15% decrease in the yield of infected parcels due to the damage of wheat seed gall nematode. The highest yield loss in infected parcels occurred in cv. Damla with 64.22% loss, while the least yield loss occurred in cv. Yüksel cultivar with 19%. Pathological symptoms, curling and twisting of the leaves, were not observed on green plants of cv. Yüksel cultivated in the field.

田间条件下种瘿线虫 Anguina tritici 给小麦造成的谷物产量损失

土耳其特拉基亚农业研究所研究了种瘿线虫 "Anguina tritici"（Steinbuch，1799 年）对一些面包小麦栽培品种农艺特性的影响。实验于 2019-2020 年生长季节在埃迪尔内的两个不同地点进行。共评估了 19 个冬季面包小麦栽培品种的感染粒数、健康粒数、感染粒率和产量。综合方差分析结果表明，施用接种物在产量方面存在显著差异（p ≤ .01）。与小麦栽培品种的对照相比，受感染地块的产量因小麦种瘿线虫的危害而减少了 52.15%。受感染地块产量损失最大的是小麦品种 Damla，损失率为 64.22%。而产量损失最小的是 Yüksel 品种，为 19.5%。Yüksel 栽培品种的产量损失最小，为 19%。在 Yüksel 栽培品种的绿色植株上未观察到叶片卷曲和扭曲等病理症状。在田间栽培的 Yüksel 栽培品种的绿色植株上未观察到叶片卷曲和扭曲等病害症状。

期刊介绍： Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays. Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes. Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
