The unpredictability and large fluctuation of the climatic conditions in rainfed regions do affect spring wheat yield and grain quality. These variations offer the opportunity for the production of better quality wheat. The effect of variable years, locations and sowing managements on wheat grain yield and quality was studied through field experiments using three genotypes, three locations for ...

Wheat stripe rust poses a serious threat to wheat production. An effective prediction method is important for food security. In this study, we developed model based on vegetation indices and meteorological features. First, time-series Sentinel-2 remote sensing images data, phenology (jointing date) was estimated using the harmonic analysis of combined with average cumulative temperature. Then, ...

Uncovering the genetic basis of agronomic traits in wheat landraces is important for ensuring global food security via the development of improved varieties. Here, 723 wheat landraces from 10 Chinese agro-ecological zones were evaluated for 23 agronomic traits in six environments. All accessions could be clustered into five subgroups based on phenotypic data via discriminant function analysis, ...

Plants of six wheat varieties (Damani, Hashim-8, Gomal-8, DN-73, Zam-04, and Dera-98) were grown under three water regimes i.e. 100% Field Capacity (FC), 35% FC and 25% FC. Results of this experiment showed highly significant difference among wheat varieties in all the studied traits and water stress conditions decreased them significantly. The superior variety Hashim-8 which indicated higher r...

Genetic improvement of grain yield is always an important objective in wheat breeding. Here, a genome-wide association study was conducted to parse the complex genetic composition of yield-related traits of 105 elite wheat varieties (lines) using the Wheat 90K Illumina iSelect SNP array. Nine yield-related traits, including maximum number of shoots per square meter (MSN), effective number of sp...

Root architecture traits are an important component for improving water stress adaptation. However, selection for aboveground traits under favorable environments in modern cultivars may have led to an inadvertent loss of genes and novel alleles beneficial for adapting to environments with limited water. In this study, we elucidate the physiological and molecular consequences of introgressing an...

To meet the increased demand for wheat consumption, wheat cultivation in Sudan expanded southward to latitudes lower than 15°N, entering a new and warmer environment. Consequently, wheat breeders developed several wheat genotypes with high yields under these environmental conditions; however, the evaluation of the end-use quality of these genotypes is scarce. In this study, we assessed the end-...
