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 Food Science"
Variation in micronutrient content of orange-fleshed sweetpotato varieties grown in different environments
Abstract:
Field experiments were conducted at three locations in Zambia
to characterize 15 sweetpotato varieties for tuber yield and
micro-nutrient content. Location and variety had significant
effect on tuber yield. Marketable yield ranged from 5.22 -
9.69 t/ha with variety Kakamega recording the least yield.
AMMI analysis also indicated significant effects of genotype
and location for tuber yield. These accounted for 53 and 11%
of the differences. The variety x location effect was significant
for iron, but not zinc. Varieties Zambezi, K566632, 199062.1
and Mayai had high levels of β-carotene.
Des expériences sur le terrain ont été conduites à trois endroits
en Zambie pour caractériser 15 variétés de patate douce pour
le rendement en tubercule. L’endroit et la variété ont eu un
effet significatif sur le rendement en tubercule. Le rendement
de Markatable s’est étendu de 5.22 à 9.69 t/ha avec la variété
Kakamega enregistrant le moindre rendement. L’analyse
d’AMMI a également indiqué des effets significatifs de génotype
et d’endroit pour le rendement en tubercule. Ceux-ci ont montré
53 et 11% des différences. L’effet d’endroit de la variété X
était significatif pour le fer, mais pas le zinc. Les variétés
Zambezi, K566632, 199062.1 et Mayai ont eu les niveaux élevés
du carotène-β.
