Phakopsora Pachyrhizi Diversity and Rust Resistance in Soybean Genotypes in Uganda

Abstract: 
The objectives of this study were twofold: (i) to validate use of SSR markers in assessing Phakopsora pachyrhizi diversity in Uganda and (ii) to assess elite soybean lines for resistance to rust in diverse locations in Uganda. A dendogram constructed from the similarity data of the isolates from the five locations grouped the isolates into two clusters. The first cluster consisted of isolates from MUARIK, Iki Iki and Mubuku and the other cluster consisted of isolates from NaCRRI and Nakabango. Maksoy 3N had the lowest rust score of 2.9 while Duiker had the highest mean score of 4.0.
Les objectifs de cette étude étaient de deux ordres: (i) valider l’utilisation des marqueurs SSR dans l’évaluation de la diversité de Phakopsorapachyrhizi en Ouganda et (ii) évaluer les lignées élites du soja pour la résistance à la rouille dans des endroits divers en Ouganda. Un dendrogramme construit à partir des données de similitude des isolats provenant des cinq sites a rassemblé les isolats en deux groupes. Le premier groupe se composait des isolats provenant de MUARIK, IkiIki et Mubuku et l’autre groupe se composait d’isolats provenant de NaCRRI et Nakabango. Maksoy 3N a obtenu le score le plus bas de la rouille de 2,9 tandis que Duiker a obtenu le plus haut score moyen de 4,0.

The 2012 RUFORUM Biennial Conference is the third 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 stakeholers 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. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under Integrated Crop Management
