โœฆ Synopsis

Triticum miguschovae, a genome addition synthetic, was used as a source for transfer of leaf rust (Puccinia recondita tritici) resistance to common wheat. This synthetic, developed from two wild species Triticum militinae and Aegilops squarrosa, proves a valuable donor of the genes for leaf rust resistance. Leaf rust resistance was transferred from T. miguschovae by both dominant and recessive genes. Stable lines phenotypically similar to their recurrent parents Kavkaz and Bezostaya 1 but differing from them in a high level of leaf rust resistance were obtained. The genes for resistance in 3 selected lines differed from each other and from the known effective genes Lr9, Lr19, and Lr24. The resistance of one of them (line 1229) is controlled by two complementary interacting genes located on chromosomes 7B and 1D was revealed by monosomic analysis.

The genetic nature of resistance to four Australian strains of Puccinia recondita was studied in the cultivar Timgalen and in three entries of the 1963 ISWRN, viz, 25 (W3300) 318 (W3301) and 409 (W3303) . Seedling resistance of Timgalen was controlled by the dominant gene Lr3 and by a recessive gene
