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"
Characterization of root development in a segregating diploid banana population as a searching basis for resistance to Radopholus similis
Abstract:
Plant parasitic nematodes are recognised as the most serious
pests of bananas wherever they are grown. Nematodes feed,
multiply and migrate inside banana roots causing necrotic and
reduced root systems. Genetic resistance to nematodes provides
a more sustainable management option to poor-resource
farmers. Traditionally, identifying resistance/tolerance of banana
varieties to nematodes depends on evaluating nematode
reproduction and (histo)pathological investigations. New
evidence indicates that there is an effect of root growth
characteristics on resistance observations. Number and root
system size seem to be the critical factors in banana tolerance
to nematodes; plants with higher root numbers and/or vigour
are less debilitated by nematodes. The proportion of primary,
secondary and tertiary roots in bananas depends on the variety
(genome group and ploidy level).
Les nématodes, parasites des plantes, sont reconnus comme
des parasites les plus dangereux de bananes bananes là où ils
sont cultivés. Les nématodes se nourrissent, se multiplient et
migrent à l’intérieur des racines des bananes, causant des
nécrotiques et la réduction des systèmes racinaires. La
résistance génétique aux nématodes fournit une option de gestion
plus durable aux agriculteurs de maigres ressources.
Traditionnellement, l’identification de la résistance et la tolérance
des variétés de la banane aux nématodes dépendent de
l’évaluation et de la reproduction des nématodes (histo) des
enquêtes pathologiques. De nouvelles preuves indiquent qu’il
existe l’effet de la croissance des racines sur les observations
de la résistance. Nombre et la taille du système racine semblent
être les facteurs essentiels de la tolérance aux nématodes de la
banane, les plantes avec un nombre plus élevé des racines et /
ou la vigueur sont moins affaiblis par les nématodes. La proportion de racines primaires, secondaires et tertiaires dans
les bananes dépend de la variété (groupe de génome et le
niveau de ploïdie).
