Estimation of genetic parameters for foot rot resistance in rye (Secale cereale)






Durability of disease resistance: 333-334

Estimation of genetic parameters for foot rot resistance in rye (Secale cereale)

Resistance to foot rot caused mainly by Fusarium spp., Pseudocercosporella herpotrichoides and Microdochium nivale (Monographella nivalis) was studied in 15 hybrids bred by crossing 6 lines from the Petkus gene pool in all combinations without reciprocals and in 11 factorial crosses between 3 Petkus inbreds and 4 inbreds from the Carsten gene pool. Cytoplasmically male sterile lines were used as maternal parents in all cases. Assessment of resistance was at 3 sites in Germany over 2 years.

Genetic analysis of resistance to leaf rust in rye (Puccinia recondita f. sp. secalis) led to the identification of two dominant resistance genes, Pr1 and Pr2. Both genes proved to be effective against a local leaf-rust population as well as a sub...

Three dominant resistance genes, Pr3, Pr4, and Pr5, were identified by genetic analysis of resistance to leaf rust in rye (Puccinia recondita f. sp. secalis). Each of the three genes confers resistance to a broad scale of single-pustule isolates (...

Genes (8) conferring resistance to wheat stem rust (P. graminis tritici) were identified in 4 inbred lines of cereal rye (S. cereale). Two of these, SrB and SrI, are allelic or closely linked.

By conventional genetic analysis, a total of 6 different genes giving resistance to rye stem rust (P. graminis secalis) were identified in 4 resistant inbred lines of rye (S. cereale). Beside their relevance in breeding for resistance, such genes...
