Race analysis of Puccinia striiformis f.sp. tritici in Iran-2017

Stripe rust of wheat, caused by Puccinia striiformis f. sp. trirtici (Pst) is an important disease in many parts of Iran. Over last two decades several epidemics have occurred in Iran causing the breakdown of widely utilized sources of resistance in wheat cultivars. Fifty isolates were collected from different parts of Iran during 2017. Eight isolates of Pst. from 2017 have been processed to date for race analysis. Infection types were assessed on a 0-9 scale 16 and 18 days after inoculation...Read complete abstract

Development of high yielding and disease resistant wheat cultivars by Cereal Crops Research Institute Pirsabak Nowshera after de

The Cereal Crops Research Institute (CCRI) is situated on the left bank of River Kabul, near village Pirsabak, 3 km east of Nowshera at an elevation of 288 m above sea level on the intersection of 74? E longitude and 32? N latitude. In July 2010, a devastating flood destroyed all the available germplasm, machineries, laboratories, and field equipment. After the flood research activities were restarted with full motivation, dedication and hard work in collaboration with PARC, ICARDA, CIMMYT,...Read complete abstract

Incorporation of rust resistance (especially stem rust race Ug99) from rice to wheat through Wheat ? rice crossing

Rust is the single largest factor limiting wheat production in Pakistan. According to the FAO reports, countries in the predicted immediate pathway of Ug99 grow more than 65 million hectares of wheat, accounting for about 25% of global wheat harvest.
Rice, a member of the same family (Poaceae) is not attacked by any rusts. Wheat, an allo-hexaploid is responsive for wide crossing. It has previously been successfully crossed with its several wild relatives and different other crop...Read complete abstract

Preliminary results on stem rust disease in a winter wheat landrace population from Central and Western Asia

Stem rust (Puccinia graminis f. sp. tritici) is a fungal disease that can significantly reduce wheat yields and quality. The goal of this study was to screen 281 winter bread wheat landraces genotypes for their reaction to stem rust disease in seedling and adult plant stage.
For seedling stage, the experiment was carried out under greenhouse conditions in Field Crops Central Research Institute in Ankara, Turkey during 2017 growing season. The genotypes were grown at 20?4?C under...Read complete abstract

Rust reactions of lines in a wheat crossing block developed by the Bahri Dagdas International Agricultural Research Institute in 2014

Rusts and drought are the principal yield-limiting factors for wheat production in the Central Anatolian region of Turkey. The aim of the study was to determine resistance sources in a crossing block of drought tolerant lines. Seedling tests involving all three rusts were carried out at CRIFC, Yenimahalle, in 2014. Inoculations were made with local Pgt (avirulent on differentials with Sr24, Sr26, Sr27 and Sr31), Pt (avirulent on differentials with Lr9...Read complete abstract

Rust reactions of wheat lines developed by another culture

Turkey is an important producer of bread wheat. Fungal diseases, including the rusts, limit production. Resistant varieties are the main strategy for rust control. In this study 33 doubled haploid lines developed by anther culture and 9 standard cultivars were evaluated for seedling (YR, LR, and SR) and adult plant reactions (YR) to rusts at the Central Research Institute for Field Crops at Yenimahalle and Ikızce in 2014. For adult plant reactions the genotypes were inoculated with local...Read complete abstract

Rust responses of some Turkish, white grained, bread wheat genotypes in preliminary yield trials

Bread wheat is the most important cereal crop in Turkey. Rusts (caused by Puccinia spp.) are the most significant diseases affecting wheat yield and quality on the Central Anatolian Plateau. The purpose of this study was to identify the reactions of 198 Turkish, white seeded, winter wheat genotypes developed by the Central Research Institute for Field Crops (CRIFC) and entered in preliminary yield trials. Adult plant and seedling tests were conducted for stripe rust whereas only...Read complete abstract

Aecial infection status of Berberis spp. in Kastamonu province of Turkey

Berberis species are important alternate hosts and generate new races of stem rust fungus, Puccinia graminis f. sp. tritici and yellow (stripe) rust fungus Puccinia striiformis. Berberis species are common in Kastamonu province of Turkey. In 2016 and 2017, surveys were conducted in Kastamonu province in order to elucidate aecial infection status of Berberis species in this region. In 2016, the central region and A?l?, Ara?, Daday, ?hsangazi, Seydiler, Ta?k?pr? and Tosya regions and in 2017...Read complete abstract

Rust resistant spring wheats from Kazakhstan and Siberia: Genotype prediction as a basis for effective resistance breeding

Northern Kazakhstan and Western Siberia are major high latitude spring wheat growing regions on the Eurasian continent. Rust epidemics can cause serious crop losses in this region. For this purpose, the Kazakhstan-Siberian network for wheat improvement (KASIB) was created in 2000. Seventy wheat cultivars and lines from a KASIB nursery were characterized for seedling and adult plant resistance (APR) to leaf rust using Australian pathotypes in greenhouse and field experiments. A molecular...Read complete abstract

Identification and characterization of winter wheat germplasm resistant to stem rust in Kenya and Turkey

A diverse set of winter wheat germplasm was screened for resistance to stem rust in large-scale trials in Kenya and Turkey during 2009-16. The study aimed to select resistant material and characterize types of resistance and possible genes, as well as evaluate agronomic traits and resistance to other diseases to select superior variety candidates and parental lines. The study material was comprised of various Facultative and Winter Wheat Observation Nurseries (FAWWON), which are developed...Read complete abstract
