Improving preharvest sprouting resistance in durum wheat with bread wheat genes
Preharvest sprouting (PHS) of durum wheat (Triticum turgidum ssp. durum (Desf.) Husn.) is an important problem in Japan, where the rainy season overlaps with the harvest season. Since there are few PHS-resistant genetic resources in durum wheat, we introduced an R-gene for red seeds, the MFT gene, and the QPhs-5AL QTL, all of which are associated with PHS resistance, into durum wheat from a PHS...
متن کاملBreeding for Salt-Resistance Using Transgressive Segregation in Spring Wheat
Hybrid populations (F3) derived from cross between four moderate salt-resistant spring wheat (Triticum aestivum L.) were assessed for transgressive segregation of salt-tolerant genotypes allowing germination and emergence at 350 mM NaCl for 30 days. The achieved Selection intensity was the order of 0.24-0.27 in these segregation populations (22-25 seedlings from 9000 seeds). Assessment of trans...
متن کاملDetection of QTLs for traits associated with pre-harvest sprouting resistance in bread wheat (Triticum aestivum L.)
Pre-harvest sprouting (PHS) is one of the serious problems for wheat production, especially in rainy regions. Although seed dormancy is the most critical trait for PHS resistance, the control of heading time should also be considered to prevent seed maturation during unfavorable conditions. In addition, awning is known to enhance water absorption by the spike, causing PHS. In this study, we con...
متن کاملDiversity of Resistance Gene Analogues in Rust Resistance and Susceptible Bread Wheat Varieties
Fungal diseases, especially leaf and stripe rusts are wheat yield reducing factors in Iran and the world. In this study, genetic diversity of 20 wheat varieties with different response to leaf and stripe rusts were studied using primers designed based on the conserved regions of plant disease resistance genes. The banding patterns of polymorphic markers were scored as dominant and number of amp...
متن کاملThe Effect of High Temperature Treatment on Wheat Streak Mosaic Virus Resistance and Certain Resistance-Related Chemicals in Bread Wheat
Background and Aims: To evaluate the effect of temperature on wheat streak mosaic virus (WSMV) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using Adl-Cross (resistant) and Marvdasht (susceptible) cultivars. Materials and Methods: Results showed that incubation at 32C changed the gene expression for resistance ...
