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...

A procedure based on acid polyacrylamide gel electrophoresis (acid PAGE) has been described. Resolution of phaseolin bands appears to be relatively superior to that obtained with basic PAGE system. The procedure discriminates S, T, C, M and B types of phaseolins; S, T and C have been reported pre...

The Musa germplasm bank established in Colombia has accessions tolerant to Yellow Sigatoka and is located at over 1310 meters above sea level. This germplasm has been characterized using morphological descriptors. However it is has been difficult to identify some accessions due to mutations and e...
