Stripe (yellow) rust disease caused by Puccinia striifarmis f. sp. tritici, is a catastrophic wheat in wheat-growing regions around the world. The objective of this study was to investigate potential sources stripe resistance and yield loss forty local varieties at four locations Egypt (Sakha, Mutubas, Qillin Biyala), under yellow pressure compared ‘Morroco’ variety, as control. To determine sl...

The fungus Puccinia striiformis f. sp. tritici (Pst) is an important threat to wheat production because it can cause stripe rust. present study aimed to identify new rust resistance genes and provide a theoretical practical basis for breeding varieties with broad spectrum, stable, durable resistance. Wheat leaves inoculated Chinese yellow 34 were collected at different time points tran...

abstract to study virulence and molecular polymorphism variation of puccinia striiformis westend. f.sp.tritici eriks. (yellow rust disease agent) in iran, 86 isolates were collected from all around the country. race determination was carried out according to johnson et al. (1972) method. in addition, isolates were analyzed by aflp method by four primer combinations . according to the results of...

Elacatinus gobies of the Caribbean have undergone rapid speciation along ecological axes, and particular species from this genus act as 'cleaners' that remove ectoparasites from larger coral reef fish, termed 'clients'. Evolutionary shifts in habitat use, behavior and lateral body stripe colors differentiate cleaners from ancestral sponge-dwelling lineages. High-contrast stripe colors associate...

Puccinia striiformis f.sp. tritici (Pst) is the causal agent of stripe (yellow) rust on wheat. It seriously threatens wheat production worldwide. The obligate biotrophic fungus is highly capable of producing new virulent races that can overcome resistance. Studying the inheritance of Pst virulence using the classical genetic approach was not possible until the recent discovery of its sexual sta...

Areca nut (Areca catechu L.) is one of the leading plantation commodities in Jambi Province which has high economic value and plays an important role as a source foreign exchange for country. plants are most widely located Betara District, West Tanjung Jabung Regency. To increase yield areca nut, it necessary to know diseases that attack percentage disease attack. It useful control nut. This st...

QTL mapping of adult plant resistance to stripe rust in the Fundulea 900 × Thatcher RIL population | Xiaocui Yan, Huimin Zheng, Peipei Zhang, Gebrewahid Takele Weldu, Zaifeng Li, Daqun Liu Agricultural Journals

A study was conducted to assess the durable resistance in a near isogenic line of spring wheat (Triticum aestivalis L.), possessing resistance gene Yr-18 to some isolates (race specific resistance) of stripe rust (Puccinia striiformis f. sp. tritici), namely Thatcher Yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...

We report here the release of four germplasm lines of hard red spring (HRS) wheat (T. aestivum L.) [Yecora Rojo Yr36– Gpc-B1 (Reg. no. GP-793, PI 638740), Yecora Rojo Lr47 (Reg. no. GP-791, PI 638738), Kern Lr47 (Reg. no. GP-792, PI 638739), and Anza Lr37/Yr17/Sr38 (Reg. no. GP-795, PI 638742)] and one durum wheat (T. turgidum L.) [UC1113 Yr36– Gpc-B1 (Reg. no. GP-794, PI 638741)], isogenic for...
