Abstract Restriction map variation in two 5-6-kb chloroplast DNA regions of five diploid Aegilops species in the section Sitopsis and two wild tetraploid wheats, Triticum dicoccoides and Triticum araraticum, was investigated with a battery of four-cutter restriction enzymes. A single accession each of Triticum durum, Triticum timopheevi and Triticum aestivum was included as a reference. More than 250 restriction sites were scored, of which only seven sites were found polymorphic in Aegilops speltoides. No restriction site polymorphisms were detected in all of the other diploid and tetraploid species. In addition, six insertion/deletion polymorphisms were detected, but they were mostly unique or species-specific. Estimated nucleotide diversity was 0.0006 for A. speltoides, and 0.0000 for all the other investigated species. In A. speltoides, none of Tajima's D values was significant, indicating no clear deviation from the neutrality of molecular polymorphisms. Significant non-random association was detected for three combinations out of 10 possible pairs between polymorphic restriction sites in A. speltoides. Phylogenetic relationship among all the plastotypes (plastid genotype) suggested the diphyletic origin of T. dicoccoides and T. araraticum. A plastotype of one A. speltoides accession was identical to the major type of T. araraticum (T. timopheevi inclusively). Three of the plastotypes found in the Sitopsis species are very similar, but not identical, to that of T. dicoccoides, T. durum and T. aestivum.

The inheritance of seedling resistance to isolate RLR 213/78 of rye leaf rust (Puccinia recondita f. sp. secalis) and race 30 of wheat leaf rust (P. recondita f. sp. tritici Rob.) was investigated in six inbred lines of rye (Secale cereale). Inbred line UM8116 was used as the susceptible parent in crosses. Inbred lines UM8003, UM8071 and UM8301 each have a single gene and UM8336 and UM8340 each have two genes for resistance to rye leaf rust. For resistance to wheat leaf rust UM8071 has a single gene, UM8003 and UM8340 each have two genes and UM8301 and UM8336 each have three genes. UM8295 is heterogeneous for reaction to both rusts. One of the genes in UM8340 may condition resistance to both rusts. The genes for resistance to RLR 213/78 appear to be independently inherited while some of the genes conferring resistance to race 30 may be identical or very closely linked. The potential of rye as a source of disease resistance for wheat and triticale improvement is discussed.Key words: Secale cereale, disease resistance, wheat leaf rust
