[Molecular genetic analysis of soriz genome (Sorghum oryzoidum)]

Molecular-genetic analysis of soriz genotypes (Sorghum oryzoidum), its paternal form Sorghum bicolor (L.) Moench (grain sorghum), possible parents (Sorghum sudanense (Piper.) Stapf. (Sudan grass) and Oryza sativa L. (rice planting)) and the nearest relatives has been carried out using microsatellite (MS) loci of sorghum and rice. Based on these data genetic distances have been calculated. It was shown that soriz do not bear DNA fragments of rice, but contains in its genome DNA fragments belonging to the Sudanese grass indicating that the origin of soriz is associated with Sorghum sudanense.
