Molecular Diversity and Disease Resistance in Sugarcane

Saccharum is a complex genus characterized by high ploidy levels and composed of at least six distinct species S. officinarum, S. barberi, S. sinensis, S. spontanum, S. robustum and S. edule. Principal Component Analysis in ten accessions of sugarcane (Saccharum officinarum L.) was conducted; analysis of variance indicated highly significant differences among the accessions for all the traits. Principal Component Analysis (PCA) is a way of identifying patterns in data, and expressing the data in such a way as to highlight their similarities and differences. Micro propagation is a technique to produce disease free plants. The aim of the present study was to investigate the response of three sugarcane accessions for callogenesis and organogenesis.
