Description Not Available
In the present investigation, the insertional polymorphisms of retro-elements were studied in the Musa germplasm available at ICAR-NRCB field gene bank using IRAP markers. The maximum number of polymorphic bands were produced by the primer pair Nikita and LTR 6150 (48) followed by LTR 6149 and 3′LTR (47) and minimum of 35 bands were produced by the primer pair Sukkula and LTR 6150. The bands produced were scored as 0 (absent) and 1 (present) and the resultant binary data was subjected to diversity analysis. The dendrogram consisted of two major clusters with members of Eumusa and Rhodochlamys in one indicating their genetic closeness and members of the genus Ensete in another cluster. Results of principal coordinate analysis were congruent to those obtained in hierarchial cluster analysis. The molecular markers used in this study could reveal intra and inter-group diversity among the Musa germplasm accessions with similarity co-efficient ranging from 0.41 to 0.99. IRAP marker system has performed excellently clustering the accessions based on both genomic and subgroup levels. The entire germplasm was found to be robust with no duplications indicating the diverse group of accessions available at ICAR-NRCB field gene bank. It has also exhibited high polymorphism and hence could be effectively used to detect the genetic relatedness among diverse genome of Musa.
