Land races are important because of their role in sustainable agriculture, organized cropping, providing resistant genomes for stress conditions and also as a confident backbone for breeding programs. In 1998, during differnet expedition programs in Ardabil province small populations of species B.lomatogona were detected and their seeds were collected (five samples). The seeds of species B.maritima were collected from different regions of Khozestan, Hormozgan and Ardabil provinces (nine samples). Beet land races (red beet and fodder beet) which are used by people for their consumption and for cattle feeding, were collected from different regions of the country (160 samples). Since 1998 during four years, each year the seed of some of the accessories after germination ans thousand seed wheight determination were planted in Kamalabad research station. Morphological caracters such as leaf and petiol color were recorded. At harvesting time, root shape, root skin color, root flesh color and root ring color were recorded and technological caracters such as sugar content, impurities and mollases were determined. From each accessory one hundred roots were selected to be used in seed propagation. In addition to field evaluation, all the accessories were sampled for ploidy level determination which based on the results all of them were diploid.
