Molecular Characterization of Early Maturing Sugarcane Clones Using Microsatellite Markers

Sugarcane is an important cash crop of the entire world including India. It alone contributes to 75% worldwide sugar trade. Molecular markers are powerful tools and provide basis for estimation genetic variability start reasonable breeding program. Microsatellite have unique ability determine extent divergence among sugarcane genotypes. The objective this study was evaluate 12 early maturing clones using 11 SSR markers. A total 55 alleles were found during amplification primers out which 21 34 shared. number shared per locus ranged from two five in case primer NKS 1 nine ten 34. Similarly no. one 34, three six 57. pairs 8 generated considerably greater percentage alleles. PIC values revealing allelic diversity frequency genotypes varied 0.034 48 0.778 9 with average 0.549. Pair-wise combinations CoSe15451 CoSe15452 showed highest similarity value coefficient (0.890). lowest be 0.490 pair CoBln15501 CoSe01421. dendogram based on marker analysis grouped into four clusters shows had maximum between each other.
