A genetic linkage map of cassava has been constructed with 132 RFLPs, 30 RAPDs, 3 microsatellites, and 3 isoenzyme markers segregating from the heterozygous female parent of an intraspecific cross. The F1 cross was made between ‘TMS 30572’ and ‘CM?2177-2’, elite cassava cultivars from Nigeria and...

Cassava (Manihot esculenta Crantz) germplasm collections are conventionally maintained by continuous vegetative propagation in the field. Tissue culture techniques provide a more convenient way to conserve germplasm. The cassava in vitro gene bank held in trust at CIAT comprises nearly 6000 acces...

Restriction fragment analysis was used to determine the variation of chloroplast DNA (cpDNA) among and within different species of Passiflora. Total DNAs of 35 accessions, representing 12 species, were digested with four restriction endonucleases. Southern blots of the restriction digests were th...

Autor: Fajardo, Diego Angel, F. Grum, M. Tohme, Joseph M. Lobo Arias, M Roca, William M. Sánchez, I.

Genetic analysis based on Random Amplified Polymorphic DNA (RAPD) was carried out on 52 accessions representing 14 species of the genus Passiflora L. using 50 random 10-mer primers. A dendrogram constructed using the Dice similarity coefficient and the UPGMA algorithm based on 626 reproducible po...

Breeding goals of yield increases, root quality improvement, and disease resistance in cassava are considerably slowed down by biological characteristics of the crop, which includes a long growth cycle, a heterozygous genetic background and a poor knowledge of the organization of crop diversity. ...

Random amplified polymorphic DNA (RAPD) analysis was performed on three F1 populations obtained from intraspecific controlled crosses of cassava. Segregation of the RAPD fragments was analyzed to determine if these can serve as genetic markers in cassava for subsequent use in linkage analysis. Se...

The construction of a detailed genetic map of cassava (Manihot esculenta Crantz) will be useful to tag agronomically important trais as well as to isolate and to clone cassava genes in the future. This map will also contribute to the understanding of cassava genomic structure and evolution. As a ...
