CIAT activities in developing biotechnology applications to cassava in the last decade are described. The strategies to identify research topics and implement in house capabilities and an international cooperative effort in cassava biotechnology are emphasized. Successful integration of selected ...
The value of intra- and interracial populations in common bean (Phaseolus vulgaris L.) needs to be determined in order to create useful genetic variation for maximizing gains from selection, broadening the genetic base of commercial cultivars, and making efficient use of available resources. Five...
For many crops with preferential vegetative propagation, or which are sterile, or have seed unresponsive to standard seed storage techniques, in vitro methods can provide a valuable adjunct to other germplasm conservation strategies. Two types of in vitro gene banks are proposed: (i) an in vitro ...
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...
Estado actual del mejoramiento del arroz mediante la utilización de especies silvestres de arroz en CIAT. Este trabajo presenta el uso de especies silvestres de arroz en la obtención de germoplasma mejorado con mayor potencial de rendimiento y una base genética ampliada. Tres especies silvestres ...
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...
