About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Plant Breeding"
Morphological and genetic characterization of mango varieties in Mozambique
Abstract:
Mangoes are economically important for Mozambique because
of adequate climatic conditions and international market
opportunities. This study compare morphological and AFLP
characterisation of 30 mango varieties from the Umbeluzi
research station, including some commercial varieties. The total
variation was lower using quantitative (89.4% similarity) than
qualitative data (60% similarity). The combined quantitative and
qualitative dendrogram had a total variation of 63% similarity
and clustered varieties in three subgroups based on high fruit
weight, high Brix content and low fruit weight. AFLP
characterisation used seven primers combinations, generating
207 data points and detecting 74.9% polymorphisms with an
average of 30 fragments per primer combination. The total
variation was low (72.49% similarity) and the dendrogram
showed five subgroups based on low fruit weight, dwarfness
and low Brix content, commercial varieties, high fruit weight
and roundish fruit shape. The combined morphological and AFLP
dendrogram was more accurate in clustering varieties based
on geographic origin within the country and from outside.
Les mangues sont économiquement importantes pour le
Mozambique en raison des bonnes conditions climatiques et les
opportunités du marché international. Cette étude compare la
caractérisation morphologique et AFLP de 30 variétés de
mangues de la station de recherche Umbeluzi, incluant certaines
variétés commerciales. La variation totale était inférieure en
utilisant une quantitative (89,4% de similarité) que des données
qualitatives (60% de similarité). Le dendrogramme combinés
quantitative et qualitative a une variation totale de la similarité
de 63% et variétés regroupées en trois sous-groupes en fonction
du grand poids de fruits, de la haute teneur en Brix et du faible
poids du fruit. La caractérisation AFLP a utilisé sept combinaisons
d’amorces, produisant 207 points de données et détectant de
polymorphismes de 74,9% avec une moyenne de 30 fragments
par combinaison d’amorces. La variation totale était faible (72,49% de similitude) et le dendrogramme a montré cinq sousgroupes
en fonction du poids faible des fruits, de la petitesse de
fruit et une faible teneur Brix, les variétés commerciales, le grands
poids des fruits et la forme arrondie fruits. Le dendrogramme
combinés morphologiques et AFLP a été plus précis en matière
de regroupement des variétés en fonction de leur origine
géographique dans le pays et à l’extérieur.
