Identification of rice blast resistance genes in the rice varieties developed with DNA-markers assistance
Abstract
Eight rice varieties of the Far East breeding have been studied by the method of DNA-typing to establish the presence of rice blast resistance genes. Six varieties possess one gene each: the varieties ‘Khankaysky 429’ and ‘Khankaysky 52’ possess the gene Pi -2, the varieties ‘Rassvet’, ‘Lugovoy’ and ‘Dolinny’ possess the gene Pi -ta, the variety ‘Almaz’ possesses the gene Pi -z. The genes Pi- 1 и Pi- b have not been found in the studied varieties. The scheme of crossing among the varieties and collection samples has been suggested for pyramiding resistance genes in the hybrids.
