"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 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. This record contains an extended abstract accepted under the theme plant breeding".
Inheritance of resistance to bacterial blight and implication for rice improvement in Uganda
Abstract:
Bacterial blight caused by Xanthomonas oryzae pv.oryzae, is
a destructive disease of rice worldwide. Resistant varieties are
the best option to avert the disease. Thirty resistance genes
identified face a wide genetic diversity exhibited by the
pathogen. Information on local isolates is not available and
genetic mechanism for resistance harbored in Ugandan
germplasm is unknown. Experimental sites were Makerere
University and NaCRRI. Differential cultivars from Africa Rice
were used to group Ugandan isolates. Seven parents were
crossed into a half diallel to produce F1 and F2 progenies for
determining the inheritance of resistance through inoculation.
Preliminary results are reported.
La brûlure bactérienne causée par Xanthomonas oryzae
pv.oryzae, est une maladie destructrice du riz à l’échelle
mondiale. Les variétés résistantes sont la meilleure option pour
éviter la maladie. Trente gènes de résistance identifiés font
face à une grande diversité génétique exposés par l’agent
pathogène. L’information sur les micro-organismes locaux n’est
pas disponible et le mécanisme génétique de résistance hébergé
dans le matériel génétique ougandais est inconnu. Les sites
expérimentaux ont été l’Université de Makerere et NaCRRI.
Les différents cultivars de riz pour l’Afrique ont été utilisés
pour les isolats du groupe ougandais. Sept plantes parents ont
été croisées pour produire des descendants F1 et F2 pour la
détermination de l’héritage de la résistance par inoculation. Les
résultats préliminaires sont rapportés.
