Abstract: In this study chromosomal preparations were made by smear methodwith flamedrying and differential stained with Giemsa technique.It wasobserved that the karyotypes of T.monococcum and T.boeoticum werevery similar.Both of them possessed a pair of small satellites and C-bands on centromere regions.However,the intercalary and telomericbands showed some disparity.No significant differences were found ei-ther their peroxidase isozyme patterns or their esterase isozyme pat-terns at early stages of seedling.Thus it...
