Anthelmintic resistance has become a serious world-wide problem and has affected ruminant productivity in many countries. Thus the search for alternative methods of worm control has been an important priority in many small ruminant industries. Manihot esculenta had been shown to reduce trichostrongyloid eggs in infected sheep fed with such fresh leaves for prolonged period of time. Thus, this s...

We examined the stem anatomy of Manihot esculenta Crantz and its hybrid with M. oligantha Pax. Cross-sections were stained with safranin-alcian blue. Manihot esculenta and its hybrid were found to have the same vascular structure in bicollateral bundles with internal phloem, which has been associated with drought resistance in other plant groups. If this association is established for cassava, ...

Cross incompatibility of wild Manihot species with cassava (M. esculenta) can impede their utilization for improving this cultigen. We tested whether compatibility could be determined based on electrophoresis results. Manihot pilosa, M. glaziovii, M. reptans, and M. cearulescens were tested. These species were allowed to hybridize with cassava to determine whether hybridization coincides with t...

Genetic variation at five microsatellite loci was used to investigate the evolutionary and geographical origins of cassava (Manihot esculenta subsp. esculenta) and the population structure of cassava's wild relatives. Two hundred and twelve individuals were sampled, representing 20 crop accessions, 27 populations of cassava's closest wild relative (M. esculenta subsp. flabellifolia), and six po...

Root crop production in Papua New Guinea is reviewed. Crops considered are the major ones (Ipomoea batatas, Colocasia esculenta, Dioscorea aiata, D. escuienta, Xanthosoma sagitti!olium), other significant root crops (Manihot esculenta, Psophocarpus tetragonolobus, Cyrtosperma chpmissonis., Alocasia macro"htza and Solanum tuberosum) and 27 minor crops. For the major and significant crops, aspect...

The main objectives of this study wre to asses the effect of Triadimefon and Hexaconazole on the non-enzymatic antioxidant potentials of Manihot esculenta Crantz during the growth and maturation period. One litre of 20 mg L triadimefon and 15mg L hexaconazole solution per plant was used for the treatment -1 -1 and control was treated with one litre of irrigation water. The treatment was given o...

Cassava (Manihot esculenta subsp. esculenta) is a staple crop with great economic importance worldwide, yet its evolutionary and geographical origins have remained unresolved and controversial. We have investigated this crop's domestication in a phylogeographic study based on the single-copy nuclear gene glyceraldehyde 3-phosphate dehydrogenase (G3pdh). The G3pdh locus provides high levels of n...

We provide the first report on the synthesis of a very productive interspecific periclinal chimera of cassava, with large and edible roots. The epidermal tissue of the chimera was formed by the cultivated species Manihot esculenta (E), and the subepidermis and internal tissue were formed by the wild species, Manihot fortalezensis (F). We used cytogenetics and morphological analyses to determine...
