To transfer multiple desirable alien genes into common wheat, we previously reported a new trigeneric hybrid synthesized by crossing a wheat - Thinopyrum intermedium partial amphiploid with wheat - Psathyrostachys huashanica amphiploid. Here, the meiotic behavior, chromosome constitution, and stripe rust resistance of F5 derivatives from the wheat - Th. intermedium - P. huashanica trigeneric hy...

Nonhost resistance is often conceptualized as a qualitative separation from host resistance. Classification into these two states is generally facile, as they fail to fully describe the range of states that exist in the transition from host to nonhost. This poses a problem when studying pathosystems that cannot be classified as either host or nonhost due to their intermediate status relative to...

Puccinia triticina f. sp. tritici (Eriks.), the causal agent of leaf rust, causes substantial yield losses in wheat production. In wheat many major leaf rust resistance genes have been overcome by virulent races. In contrast, the prehaustorial resistance (phr) against wheat leaf rust detected in the diploid wheat Einkorn (Triticum monoccocum var. monococcum) accession PI272560 confers race-inde...

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, ...

Hundreds of quantitative trait locus (QTL) have been reported in diverse types hexaploid wheat (Triticum aestivum L.) populations but direct comparisons QTLs different studies and are still challenging due to the lack physical positions for most QTLs. Here, we used International Wheat Genome Sequencing Consortium (IWGSC) RefSeq v2.0 map all markers associated with leaf spot (Ls), rust (Lr), str...
