Abstract excerpt

Wheat line Tr129 is resistant to stem rust, caused by Puccinia graminis f. sp. tritici (Pgt). The resistance in Tr129 was reportedly derived from Aegilops triuncialis, but the origin and genetics of resistance have not been confirmed. Here, genomic in situ hybridization (GISH) showed that no Ae. triuncialis chromatin was present in Tr129. Genetic and phenotypic analysis was conducted on F2 and DH populations from...
