Abstract

Two native and three high yielding potato varieties available in Bangladesh were studied cytogenetically   at molecular level to get a preliminary idea about their genomes. These varieties possess 2n = 4x = 48   chromosomes. Each variety has definite centromeric formula. Presence of maximum metacentric   chromosomes suggested their karyotypes as symmetric type. The range of individual chromosomal and total   length of 2n chromosome complements was also distinct in five varieties. Heteromorphicity regarding   centromeric position suggesting the occurrence of structural aberration in respective homologous pairs. Seven   primer combinations were used for RAPD finger printing. A few common RAPD bands suggested the   sharing of genomic fragments among five varieties. However, each variety showed specific characteristic   RAPD bands. Therefore, each variety has characteristic karyotype and RAPD markers.
