Abstract

Kharouf, Sh., Sh. Hamzeh and M.F. Azmeh. 2021. Races Identification of Wheat Rusts in Syria during the 2019 Growing Season. Arab Journal of Plant Protection, 39(1): 1-13. Wheat rust diseases, caused by Puccinia striiformis f. sp. tritici (stripe or yellow rust), P. triticina f. sp. tritici (leaf or brown rust) and P. graminis f. sp. tritici (stem or black rust) are important factors affecting both durum and bread wheat production in Syria. Considerable losses were caused by these diseases, especially stripe rust, estimated at more than one million metric tons, in the 2010 season, out of 5 million anticipated production. Therefore, it is essential to monitor and follow the movement of these three rust physiological races. In the 2019 growing season, 165 wheat fields were surveyed, and 312 samples were collected and characterized. Ten races of stripe rust were identified in ten locations, of which, four represent new record in Syria, namely the races 16E154, 69E150, 264E46 and 258E64. In addition, four races of leaf rust were identified in four locations, one of which (BKLP) is a new record in Syria. In addition, three previously recorded stem rust races were identified from three different locations. It should be mentioned that the newly recorded races of stripe rust are able to overcome resistance genes Yr1 and Yr5, on which the resistance of durum wheat cultivars such as "Cham3" depended, with a disease severity of 40S recorded in the same locations. It is also worth noting that the stripe rust race 462E128 (warrior) was not detected in the isolates studied. Likewise, the stem rust race Ug99 was also not identified, and because of the aggressiveness of this race, continuous inspection through field surveys accompanied with pathogenicity tests is essential during the coming seasons.

2019年叙利亚小麦锈病品种鉴定
Kharouf、Sh.、Sh.Hamzeh和M.F.Azmeh。2021.2019年生长季节叙利亚小麦锈病的种族鉴定。《阿拉伯植物保护杂志》,39(1):1-13。小麦锈病是影响叙利亚硬粒小麦和面包小麦生产的重要因素。这些疾病造成了相当大的损失,特别是条锈病,在2010年季节,预计产量为500万吨,估计损失超过100万公吨。因此,有必要监测和跟踪这三个锈生理小种的运动。在2019年的生长季节,对165块麦田进行了调查,收集并鉴定了312个样本。在10个地点鉴定出10个条锈病小种,其中4个代表叙利亚新记录,即16E154、69E150、264E46和258E64。此外,在四个地点发现了四个叶锈病小种,其中一个(BKLP)是叙利亚的新记录。此外,在三个不同的地点发现了三个先前记录的茎锈病小种。值得一提的是,新记录的条锈病小种能够克服硬粒小麦品种(如“Cham3”)抗性所依赖的抗性基因Yr1和Yr5,在相同位置记录的疾病严重程度为40S。同样值得注意的是,在所研究的分离株中没有检测到条锈病小种462E128(战士)。同样,茎锈病小种Ug99也没有被鉴定出来,由于该小种的攻击性,在接下来的季节里,通过实地调查和致病性测试进行持续检查是至关重要的。关键词:条(黄)锈,叶(褐)锈,茎(黑)锈,小种鉴定,小麦,叙利亚
