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"
Developing a broad soybean germplasm base and durable resistance to soybean rust disease in Uganda
Abstract:
Soybean rust, Phakopsora pachyrhizi is a major threat to
soybean production world-wide. In Uganda breeding for soybean
rust resistance has taken priority over other objectives since
the first disease rust outbreak in 1996. Three resistant varieties
Maksoy 1N, Maksoy 2N and Namsoy 4M released by the
soybean breeding programme are showing signs of resistance
breakdown. This calls for broadening of the genetic base of
local breeding material to be able to cope with soybean rust
which is expected to be more severe in countries where it is
endemic. Several other strategies can be implemented to control
soybean rust. These include germplasm enhancement and
breeding for durable resistance. This research seeks to use
durable partial resistance to select candidate genotypes to
incorporate into the breeding programme. Key outputs of the
research will include resistant genotypes, inventories of genetic
variability present in the available soybean germplasm and a
description of rust races in Uganda.
La rouille de soja, Phakopsora pachyrhizi est une menace
importante à la production de soja dans le monde entier. En
Ouganda, la multiplication pour la résistance à la rouille de soja
a pris la priorité au-dessus d’autres objectifs depuis la première
manifestation de cette maladie en 1996. Trois variétés résistantes
Maksoy 1N, Maksoy 2N et Namsoy 4M enregistrées par le
programme de production du soja montrent des signes de
défaillance de la résistance. Ceci demande l’élargissement de
la base génétique du matériel de multiplication local pour pouvoir
faire face à la rouille de soja qui pourrait être plus grave dans
les pays où elle est endémique. Plusieurs autres stratégies
peuvent être mises en application pour contrôler la rouille de
soja. Ceux-ci incluent le perfectionnement du matériel génétique
et la multiplication pour la résistance durable. Cette recherche
cherche à employer la résistance partielle durable pour choisir les génotypes candidats à incorporer au programme de
reproduction. Les produits essentiels de la recherche incluront
des génotypes résistants, des inventaires de la variabilité
génétique actuelle dans le matériel génétique disponible de soja
et une description des lignées de rouille en Ouganda.
