Genus of Secale contains one cultivar rye and five wild species in the territory of Georgia, Caucasus ecoregion. Historically, cultivar rye (Secale cereale) was distributed in the territories of Georgia from lowlands to high mountain areas at high altitudes of 2300 m. S. cereale had 14 varieties in many areas of Georgia and 5 varieties are distributed only on territories of Caucasus ecoregion. Some varieties had erosion and degradation and their seed material are distributed to genbanks. Two semi-wild ryes (S. segetale and S. vavilovii) growing as weedy rye in the fields with wheat and barley from lowlands at elevations higher than 1400 m and are related to semi-arid climates in eastern and south territories of Georgia. Two wild species (S. anatolicum and S. montanum subsp. kuprijanovii) are located on high forest zone and on subalpine meadows at higher elevations of 2300 m to lesser and Western Greater Caucasus Mountains. Another wild species (S. sylvestre) grows on lowlands at 200 m from Black Sea dunes in Georgia. Morphometric analysis revealed similarity between cultivated rye and these wild species. This hypothesis was proposed that cultivar rye forms can arise as a result of interspecific hybridization processes between studied wild species.
