Plant disease has long been one of the major threats to world food security due reduction in crop yield and quality. Accurate precise diagnosis plant diseases a significant challenge. Cost-effective automated computational systems for would facilitate advancements agriculture. The objective this paper is explore computer vision based Artificial Intelligence method automating identification yell...
The causal agent of yellow rust (Puccinia striiformis f.sp. tritici) gained special attention in Serbia since the 2013/2014 production year, although its presence genetic collection at Rimski šančevi was noted by Jevtić et al. as early 1997. Considering mode transmission and high ability to overcome host plant resistance, aim this study is highlight factors that influence dynamics occurrence ma...
most part of durum wheat is produced in semitropical dryland regions in iran. heat and drought stresses are the main constraints in these regions. so, identification of durum wheat cultivars with high yield and tolerant to these stresses is the main breeding strategy in dryland agricultural research institute. the genotype capeiti was evaluated at gachsaran agricultural research station from 19...
aftab cultivar originated from national cereal breeding programs .the new cultivar was evaluated in international high rainfall wheat yield trial nursery at gachsaran and gonbad agricultural research stations (2008-2009). due to optimum grain yield and other agronomic traits, the new cultivar was tested in advanced yield trials in gachsaran, ilam, khoram abad and gonbad research stations (2009...
Stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive diseases of wheat worldwide. Planting resistant cultivars is an effective way to control this disease, but race-specific resistance can be overcome quickly due to the rapid evolving Pst population. Studying the pathogenicity mechanisms is critical for understanding how Pst virulence changes...
$ 3 mm long dipteran ( ̄y), commonly known as the fruit ̄y. $ Adult ̄y is yellow-brown in colour, with oval wings and rust-red eyes. $ y180 Mb genome, as four chromosomes X/Y, 2, 3 and 4. $ Genome sequence substantially completed 24 March 2000. $ 120 Mb euchromatic region of genome comprises 13 601 predicted genes. $ Has made signi®cant contribution to understanding of development. $ Large-scale P...
Stripe (Yellow) rust caused by Puccinia striiformis f.sp. tritici (Pst) is important wheat diseases causing serious damage on cultivated susceptible variety. The yellow assessment was conducted during main rainy season of 2018/19 at Ada’a, Lume and Gimbichu using zigzag method assessment. Disease data’s, agro-eological data other parameters were recorded. disease prevalent all dis...
Stripe rust or yellow rust (YR), caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most important diseases of wheat (Triticum aestivum L.). Widespread deployment of resistant cultivars is the best means of achieving durable disease control. The red grain, spring wheat cultivar Napo 63 produced by CIMMYT in the 1960s shows a high level of adult-plant resistance to stripe rust in...
زنگ زرد گندم توسط قارچ puccinia striiformis westend f.sp.tritici ایجاد می شود و از عوامل عمده کاهش دهنده عملکرد کمی و کیفی گندم بویژه در مناطق سرد و مرطوب می باشد. در این مطالعه تغییرات ساختاری و تنوع نوکلئوتیدی برخی از ژن های مقاومت به زنگ زرد در هفت ژنوتیپ گندم نان با درجات متفاوت مقاومت به زنگ زرد بررسی شد. ژن های مقاومت به زنگ زرد با استفاده از آغازگرهای اختصاصی طراحی شده بر اساس توالی های ...
Abstract To develop and optimize protective measures in the CCR conditions, an analysis of epidemic resistance zoned varieties hybrid lines spring wheat to causative agents septoria, brown yellow rust was carried out; effect fungicides, biological agents, their binary mixtures studied for crops. Among selection material wheat, numbers were identified selected as potential genetic sources donors...
