Karyomorphological analysis with differential staining of nine Cicer arietinum L. varieties

摘要

Karyomorphological study of nine varieties of Cicer arietinum L. (chickpea) released from BARI wasinvestigated. The nine varieties have 2n = 16 metacentric chromosomes revealing symmetrical karyotype.The first pair of chromosome in each variety has satellites on short arms. Nine varieties showed more or lesssimilar karyotypes, differed in respect of other karyological features like orcein, CMA and DAPI stainingproperty of interphase nuclei and prophase chromosomes. Therefore, the differential staining property ofinterphase nuclei and prophase chromosomes may be useful to distinguish nine varieties of Cicer arietinumL. in spite of having similar karyotypes.
