A marker-assisted background selection (MABS)-based gene introgression approach in wheat (Triticum aestivum L.) was optimized, where 97% or more of a recurrent parent genome (RPG) can be recovered in just two backcross (BC) generations. A four-step MABS method was developed based on 'Plabsim' computer simulations and wheat genome structure information. During empirical optimization of this meth...

Northern areas of the western United States are one of the most productive wheat growing regions in the United States. Increasing productivity through breeding is hindered by several biotic stresses which slow and constrain targeted yield improvement. In order to understand genetic variation for stripe rust (Puccinia striiformis f. sp. tritici), Septoria tritici blotch (Mycosphaerella graminico...

Bu çalışmada 59 buğday (55 ekmeklik ve 4 makarnalık) genotipi sarı pas, kahverengi kara külleme fusarium başak yanıklığı hastalıklarına dayanıklılık genleri ile yüksek protein, gluten mukavemeti bin tane ağırlığı gibi kalite özellikleri ilgili allele özel 14 basit dizi tekrarları (SSR) primeri taranmıştır. Araştırma sonuçlarına göre, protein Gpc-B19 alleli (UHW89 primeri) genotipte, pas Lr34 (X...

Puccinia striiformis f. sp. tritici (Pst) causes wheat stripe rust (also called yellow rust, Yr), one of the most important diseases worldwide. Characterization virulence in Pst populations is essential for developing cultivars with effective and durable resistance to control disease. A total 138 races, including 120 races that were not previously reported, identified from collections made Cana...

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a devastating disease of wheat in Turkey and worldwide. This pathogen can overcome known resistance genes negatively affect the production. The objectives this study were to determine virulence patterns stripe rust isolates collected from coastal areas (Aegean Mediterranean regions) Turkey, examine genetic diversity populations simp...

The knowledge of genetic variability, combining capability, and gene activity are vital in enhancing wheat productivity. Six diverse genotypes, Anmol91, Fatehjung16, Khattakwal, Auqab2000, PR128, Abaseen 2021, KT06, crossed with three strip rust-resistant lines, i.e., YR5, YR10, YR15, employed line × tester hybridization. analysis determined that the general ability (GCA) specific (SCA) varianc...
