Wheat is a crop with spring and winter types and wide adaptability to different climate conditions. The wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (VRN) genes play pivotal role in determining spring and winter types. In this study, 395 Iranian wheat landraces were characterized with specific primer pairs designed based on VRN-...

Sumintary. A spring wheat (Triticumo aestivumin) and(I anl obligate winter wheat (Triticumt compactutm) variety were each grown for 5 weeks in controlled environments at 20 and 250. The threshold for flower induction in the winter wheat was 4 to 5 weeks at 20, whereas the spring wheat had no low temperature requirement for flowering. Changes in the levels of carbohydrate and nitrogen fractions ...

low temperature (lt) acclimation, phenological development and vernalization requirement are known to influence the expression of frost tolerance (ft) in winter cereals. a phenotypic study was undertaken to determine the interrelationship between developmental stages and ft in hardy winter wheat and rye cultivars acclimated under field condition in the cold and temperate regions of iran. winter...

Members of the grass subfamily Pooideae are characterized by their adaptation to cool temperate climates. Vernalization is the process whereby flowering is accelerated in response to a prolonged period of cold. Winter cereals are tolerant of low temperatures and flower earlier with vernalization, whereas spring cultivars are intolerant of low temperatures and flower later with vernalization. In...

wheat, a globally important food crop, is widely grown in various regions of the world. wheat’s wide adaptation to different climatic conditions is strongly controlled by vernalization (vrn), photoperiod (ppd) and earliness per se (eps) genes. in this study, 395 iranian wheat landraces were characterized by applying markers for the vernalization genes vrn-b1, vrn-d1, and vrn-b3. based on specif...

Vernalization is one of the most important traits for the adaptability of wheat; detecting variation in genes regulating the response of wheat to vernalization is of importance for classifying winter phenotypes. Ecotilling is a high throughput reverse genetics approach for detecting single nucleotide polymorphisms (SNPs) in the genes of a natural population. To simplify methodology and decrease...
