Plant Resistance Gene

AC Taber is a hard red spring wheat cultivar that has had long-lasting resistance to the leaf rust fungus Puccinia triticina. The objective of this study was to determine the chromosome location of the leaf rust resistance genes in AC Taber. The leaf rust-susceptible cultivar Thatcher was crossed with AC Taber to develop an F6 recombinant inbred line (RIL) population. The RILs and parents were evaluated for segregation of leaf rust resistance in five field plot tests and in two seedling tests to race BBBDB of P. triticina. A genetic map of the RIL population was developed using 90,000 single nucleotide polymorphism markers with the Illumina Infinium iSelect 90K wheat bead array. Quantitative trait loci (QTLs) with significant effects for lower leaf rust severity in the field plot tests were found on chromosomes 2BS and 3BS. The same QTLs also had significant effects for lower infection type in seedlings to leaf rust race BBBDB. The gene on 2BS was the adult plant resistance gene Lr13, and the gene on 3BS mapped to the same region as the adult plant resistance gene Lr74 and other QTLs for leaf rust resistance. Kompetitive allele-specific PCR assay markers linked to the 2BS and 3BS regions were developed and should be useful for marker-based selection of these genes.

Differential Cultivars

Host resistance is the most economical way to manage wheat stripe rust caused by Puccinia striiformis f sp tritici The cultivar Claire was released in 1999 and until recently remained highly resistant to the disease in the United Kingdom While Claire was considered durably resistant to stripe rust in New Zealand it is now categorised as moderately susceptible The present study investigated whether racespecific resistance was responsible for this breakdown in resistance and whether cv Claire retains useful durable resistance A rust culture from cv Claire was compared with a pre2005 culture on a set of differential cultivars The seedling resistance in cv Claire was racespecific Greenhouse and field experiments suggest that the adult plant resistance in cv Claire has been reduced in the presence of a more virulent stripe rust population Remaining adult plant resistance is insufficient to provide adequate control of stripe rust in New Zealand wheat crops
