Stem rust of wheat caused by Puccinia graminis Pers. f.sp. trtici Eriks and E. Henn., is the most damaging fungal disease both common ( Triticum aestivum L.) durum turgidum L., ssp. Durum) wheat. Continuously emerging races virulent to many commercially deployed qualitative resistance genes have remarkable loss worldwide threaten global production. The objectives this study were evaluate response a panel 283 lines assembled International Maize Wheat Improvement Center (CIMMYT) multiple stem...
Identifying a stable high-yielding variety is challenging. This paper reports and durum wheat candidates identified using AMMI, GGE biplot models, stability parameters. Twenty-five lines were evaluated in 13 environments 2018 2019 triplicate row-column design. stability, analyses conducted packages the R statistical software. AMMI indicated highly significant effects of environments, genotypes, their interactions on grain yield. The highest proportion total sum squares accounted for by...
Abstract Many of the major stem rust resistance genes deployed in commercial wheat ( Triticum spp.) cultivars and breeding lines become ineffective over time because continuous emergence virulent races. A genome‐wide association study (GWAS) was conducted using 26,439 single nucleotide polymorphism (SNP) markers 280 durum [ turgidum L. subsp. Durum (Desf.) Husnot] from CIMMYT to identify genomic regions associated with seedling races TTKSK, TKTTF, JRCQC, TTRTF field TKTTF JRCQC. The...
Abstract Optimum seeding rate and row spacing are important for uniform crop establishment harvest of quality seed. Field experiment was conducted at three locations in 2014 2015 to study the influence seed on multiplication factor yield durum wheat. Triplicate split plot design used. The highest found a 125 kg ha −1 with 10 cm but not significant rates 100 spacing, 75 20 2014, 150 Debre Zeit. At Chefe Donsa, (4.75 ton) harvested . Minjar, affected by rate. Seed higher 50 ratio (97.3)...
Stem rust caused by the fungus Puccinia graminis f.sp. tritici Eriks. & E. Henn. ( Pgt ) threatens global production of both durum wheat Triticum t urgidum L. ssp. (Desf.) Husnot and common aestivum L.). The objective this study was to evaluate a recombinant inbred line (RIL) population from cross between susceptible parent ‘DAKIYE’ resistant ‘Reichenbachii’ developed International Center for Improvement Maize Wheat (CIMMYT) 1) seedling response races JRCQC TTRTF 2) field bulk current...
