Seedling Resistance

The genetics of seedling resistance to leaf rust (Puccinia recondita Rob. ex. Desm.) was investigated in what (Triticum aestivum L.) introductions PI 268454, PI 58548 and PI 268316, originally collected in Afghanistan, China and Iran, respectively. PI 268454 was heterogeneous for resistance. A selection (PI 268454a) has a gene that confers a 1+ reaction while a second selection (PI 268454b) probably has resistance gene Lr2b. PI 58548 has two genes for resistance, one giving a 1+ reaction and the second a 2+. These two genes interact to produce a; 1 reaction. PI 268316 has three interacting genes, one giving a 1+ reaction, the second a 2+ and a third resistance gene similar to LrB. The gene giving the 1+ reaction was common to all three introductions. PI 58548 and PI 268316 carry different genes for infection type 2+. Backcross lines of the single genes were produced. Implications to breeding for disease resistance of genes interacting to produce different phenotype are discussed.

Aim. The aim of the study was to compare diversity of groups of winter common wheat varieties of the Steppe and the Central Forest-Steppe of Ukraine by storage protein loci and some disease resistance genes and to reveal peculiarities of varieties released after 1995. Methods. SDS and APAG electrophoresis was used to identify genotypes at the Glu-1, Gli-1, and some minor gliadin loci. PCR analysis was employed to study alleles of the disease resistance genes Lr34/Yr18/Pm38/Sr57/Bdv1, Tsn1, Tsc2, TDF_076_2D, and Cre-8. Results. Significant differences in frequencies of alleles at most marker loci were revealed. Nonrandom associations between disease resistance gene alleles as well as storage protein alleles were detected. Conclusions. The retention of a set of predominant alleles of a certain zone in different periods of breeding was confirmed. The appearance of new allele associations in the groups of varieties of the Steppe (in particular Gli-A1g and Glu-B1al) and the Central Forest-Steppe (1AL/1RS and Glu-B1d) in the last two decades was noted. Keywords: Triticum aestivum L., varieties, storage proteins, resistance genes, alleles.
