Four morphological types of cassava clone MCol 2215 (Venezolana) have been observed in El Carmen de Bolivar, Colombia. Therefore, tissues from leaf apical meristems and from root tips were assessed by electrophoresis using 4 isoenzymes as genetic markers (esterase, diaphorase, acid phosphatase, o...
En El Carmen de Bolivar, Colombia, se han observado 4 morfotipos de yuca clon MCol 2215 (Venezolana); por tanto, se evaluaron tejidos provenientes de meristemas apicales foliares y de brotes o puntas radicales mediante electroforesis usando 4 isoenzimas como marcadores geneticos (esterasa, diafor...
Five new marker genes in cassava are described; they control the following traits: chlorophyll production in seedlings, stem growth habit, stem collenchyma color, root parenchyma color, and leaf lobe shape (pandurate vs. normal). Names were proposed for each loci and dominant and recessive phenot...
In large ex situ germplasm collections, such as that maintained at CIAT for cassava, it is common to observe duplicates. The presence of duplicate clones increases the cost of conservation without contributing to representation or the available genetic base for crop improvement. To identify group...
Esterase isozymes were chosen for fingerprinting CIAT`s cassava germplasm colleciton, because of (1) their technical repeatability; (2) high polymorphism (i.e., many alleles per locus); and (3) high numner of bands detectable in cassava clones (i.e., at least a few loci are expressed). A total of...
Genetic studies of two isozyme loci have been carried out in root tips of eight cassava F1 progenies using polyacrylamide gel electrophoresis. Two loci, esterase-1 (East-1), the most distant cationic region, and glutamate oxaloacetate transaminase-1 (Got-1), the most proximal anionic region, were...
