Target Region Amplification Polymorphism (TRAP) for Assessing Genetic Diversity in Sugarcane Germplasm Collections
Target region amplification polymorphism (TRAP) is a fairly new PCR-based molecular marker technique which uses gene-based information for primer design. The objective of this study was to evaluate the utility of TRAP markers for assessing genetic diversity and interrelationships in sugarcane germplasm collections. Thirty genotypes from the genera Saccharum, Miscanthus, and Erianthus were used ...
متن کاملEvaluation of microsatellite markers for genetic diversity analysis among sugarcane species and commercial hybrids
Increasing sugar productivity is the main concern of sugarcane (Saccharum officinarum) breeding programs. The complexity and size of the sugarcane genome is a major limitation in genetic improvement. Characterization of sugarcane wild germplasm provides essential information on genetic diversity that breeders utilize for crop improvement. The objective of this study was to evaluate the utility ...
متن کاملPhylogenetic relationships among Saccharum clones in Pakistan revealed by RAPD markers.
Forty sugarcane genotypes (clones), including elite lines, commercial cultivars of Saccharum officinarum and S. barberi clones, were fingerprinted with 30 RAPD markers, using a PCR-based marker assay. The genetic distance for RAPD data was determined according to Nei, and relationships between accessions were graphed in a dendrogram. Genetic distance values ranging from 16.2 to 86.3% were obser...
متن کاملGenetic studies of "noble cane" for identification and exploitation of genetic markers.
Forty genotypes (clones) of sugarcane, including elite lines, commercial cultivars of Saccharum officinarum and clones of S. barberi were fingerprinted with 50 SSR markers using a PCR-based marker assay. Nei's genetic distances for SSR data were determined and relationships between accessions were portrayed graphically in the form of a dendrogram. Genetic distance values ranging from 0.60 to 1....
متن کاملMolecular characterization of Miraflores peach variety and relatives using SSRs
Some traditional peach varieties, originated from the region of Aragón (Spain), were analysed by SSRs (Simple Sequence Repeats). The aim of this research was to characterize 19 clones related to ‘Miraflores’ variety, with unknown pedigrees, to assess their genetic diversity and to elucidate their possible relationships with 10 traditional peach varieties. Twenty SSR primer pairs with high level...
