Information about landrace diversity has practical implications for its preservation, efficient management and effective utilization in breeding programmes. The objectives of the study were to (i) compare molecular and agronomic diversity estimates of two divergent landraces (AA007/92 and AA098/9...

An AFLP genetic variability study of the Colombian collection of lulo Solanum quitoense and related species of section Lasiocarpa was carried out. The aim was to elucidate the genetic polymorphism of such collection and interspecific affinities. Two primer combinations, E-ACG/M-CAT and E-ACG-M-CT...

Germplasm of the calabash tree (Crescentia cujete L.) was collected in five major regions of Colombia, i.e. the Andes, Caribbean, Amazon, Orinoco, and Pacific regions. Collecting this multipurpose tree was guided by the indigenous knowledge of farmers and artisans in each region. Large variation ...

The cassava core collection was selected to represent, with minimum repetitiveness, the potential genetic diversity of the crop. The core (630 accessions) was chosen from the base collection (over 5500 accessions) on the basis of diversity of origin (country and geographic), morphology, isozyme p...

Angular leaf spot (ALS), caused by the fungus Phaeoisariopsis griseola (Sacc.) Ferr., is one of the most important diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical bean producing areas. The common bean accession G 10474 has been widely resistant to P. griseola, includin...

Congruity and recurrent backcross interspecific hybrids between common bean (Phaseolus vulgaris L.) and tepary bean (P. acutifolius A. Gray) were compared for the amount of introgression occurring between genomes by amplified fragment length polymorphism (AFLP) markers. A total of 60 genotypes we...

Corky ringspot disease (CRS) resistance is an ideal target trait for breeding using marker-assisted selection (MAS) due to the high variability in field disease incidence that complicates screening for resistance. To develop molecular marker(s) associated with CRS resistance, a linkage map was co...

Progress in the breeding of plantain and banana has been restricted by the complex genetic structure and behaviour of cultivated polyploid Musa. Genetic improvement has been hindered due to the large amount of space required for growth and maintenance of plant populations, in addition to the long...
