ANALYSIS OF GENETIC VARIATION IN DIFFERENT BANANA VARIETY (MUSA) SPECIES BY RANDOM AMPLIFIED POLYMORPHIC DNA.

Banana plant is one of the most important food crops in the world. It also has rich source of carbohydrates, vitamin-B and also provides good source of essential ions and nutrients. The multipurpose use of this plant has attracted the global attention which promotes many researchers to conduct preliminary studies on genetic diversity of this plant. The current study was focused to study the DNA finger print and asses the genetic diversity among the varieties of banana. A total of five banana cultivars were collected in and around Coimbatore. The DNA was isolated from the samples and confirmed by random agarose gel electrophoresis with respective markers. The dendrogram was constructed using a 1D advanced software, D Gel DAS (Digital Gel Documentation Analysis Software).The coefficient ranged for Rasthali and Pooven is 0.749.Red banana and Nendran false between 0.857. The highest coefficient is showed by Grand nine variety of 0.873.
