Synthetic hexaploid wheat (SHW) is a valuable resource for breeding because it possesses more desirable traits, such as better yield and abiotic and biotic stress tolerance than common wheat. In this study, our group developed a SHW line, named ‘SynDT’, which has markedly better characteristics than Korean bread wheat ‘Keumkang’. The SynDT line is thermotolerant as it rapidly expresses heat shock proteins under heat stress. In addition, this line exhibits resistance to leaf rust by inducing the expression of antifungal enzymes, mainly chitinase, along with the rapid and high expression of pathogen-related genes. Moreover, it possesses the favorable traits of its parent wheat lines Triticum durum #24 and Aegilops tauschii #52. Therefore, the SynDT wheat line can be used as a breeding material for improving local common wheat cultivars.

Summary:Lengths of seedlings aboveground parts of nine wheat varieties grown in greenhouse were reduced by 4-20%. They were tested during April at around 20 o C after twice daily treatments with glyphosate based herbicide (0.5 ml in 1l water solution, 0.5 dl on 0.5 m 2 ). When results of permanent artificially and daily lighted trials were compared, four groups of varieties were recognized same as was when near isogenic lines containing different leaf rust resistance genes (Lr NILs) were focused in winter. Growth of variety Pobeda decreased more when seedlings were not permanent lighted which confirmed the common herbicide effect. Tolerance of other varieties was again explained by enzymatic degradation of glyphosate and chlorophyll inhibition by consequential phosphorus acids. Varieties Simonida, Tavita and Rapsodia were similar by reaction to glyphosate as Lr 1 and Lr 21 NILs. NS 40S contained Lr 3a with increased hydrolytic stability compared to Lr 24 but able to cleave external single phosphorus for the difference of Lr 19 or Lr 29. Their final effect was similar to previous stated of Lr 15 NIL during the winter. Varieties Gora and Metka had gene Lr 19, Enigma Lr 29 while Ilina Lr 24. Focusing herbicide residua transfer in seed probability, accounting optimal time for recovering ability of chlorophyll and temporary higher temperatures necessary for Lr genes even parasite free activity the varieties Gora, Metka and Enigma appeared to be possible solution for glyphosate apply near wheat heading in semiarid regions.
