Summary
Two genes for resistance to Puccinia graminis f. sp. tritici were located in chromosome 2B of Kota wheat. Both were mapped in the long arm. The first designated Sr28 was situated distally to Sr9 and showed 34·6±2·8 per cent recombination with the centromere. The second gene, which was not definitely distinguished from Sr16 either on the basis of recombination or by its response to several pathogen cultures, was inherited independently of the 2B centromere and of Sr9, but showed 38·2±1·9 and 29·2±4·2 per cent recombination with Sr28. Comparisons of present results with those from earlier studies suggested that Kota possesses at least five genes for resistance.
