Bangladesh Agricultural Research Institute (BARI) released seven variants of Allium L. such as BARI piaz-1, BARI piaz-2, BARI piaz-3, BARI piaz-4, BARI piaz-5, BARI patapiaz-1 and BARI chive-1 were analyzed to know the mitotic nature of interphase nuclei and prophase chromosome by using aceto-orcein staining. All the Allium variants of the analysis showed homogeneous staining nature in both interphase and prophase that categorized as ‘diffuse type’ and ‘Continuous Type’, respectively but differ in presence of nucleoli number in interphase. The details of the current analysis indicate that mitotic behavior of interphase nuclei and prophase chromosome of BARI variants of Allium are mostly similar and stable in character.
