"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 diseases".
Studies into slow rusting resistance among selected wheat lines
Abstract:
Wheat is an important staple crop in East Africa whose
consumption outweighs its production partly due to the
emergence of a virulent strain of Puccinia graminis fsp tritici,
strain ug99 that cause stem rust disease. A study was carried
out at Kenya Agricultural Research Institute, Njoro to identify
sources of resistance to stem rust. Significant differences were
noted for the final disease severity scores and their area under
disease progress curve (AUPDC) values. The following lines
exhibited trace response and least AUPDC values; 1168.6,
SERI.1B*2/3/KAUZ*2/BOW//KAUZ/4/PBW343*2/
TUKURU/5/C80.1/3*BATAVIA//2*WBLL1, SUNCO//
TNMU/TUI and R07 F4-21258 which are entries 1, 7, 19 and
21, respectively. Lines which showed slow rusting
characteristics with least disease and low AUDPC values
included; CWANA 1st SR RESIS. ON - ETH - OS71, MON’S’/
ALD’S’//TOWPE’S’, 87 and WHEAR/VIVITSI//WHEAR (2,
3, 4 and 14, respectively). These elite lines could form the basis
for breeding for durable resistance in wheat. Identified
resistance could also be introgressed into high yielding
backgrounds.
Le blé est une culture vivrière importante en Afrique de l’Est
dont la consommation dépasse la production, en partie à cause
de l’émergence d’une souche virulente de Puccinia graminis
fsp tritici, la souche ug99 qui cause la maladie de la rouille des
tiges. Une étude a été réalisée dans un Institut de Recherche
Agronomique du Kenya, à Njoro pour identifier les sources de
résistance à la rouille de la tige. Des différences significatives
ont été notées pour les critères finals de gravité de la maladie
et de leur région sous les valeurs de la courbe de progression
des maladies (AUPDC). Les lignées suivantes ont exposé la
réponse de trace et au moins les valeurs AUPDC : 1168.6,
SERI.1B*2/3/KAUZ*2/BOW//KAUZ/4/PBW343*2/
TUKURU/5/C80.1/*BATAVIA// 2*WBLL1, SUNCO//
TNMU/TUI et R07 F4-21258 qui sont les entrées 1, 7, 19 et 21, respectivement. Les lignées qui ont montré les lentes
caractéristiques d’enrouillement avec au moins la maladie et
les faibles valeurs AUDPC ont inclus : CWANA premier SR
RESIS. ON - ETH - OS71, MON’S’/ALD’S’//TOWPE’S’,
87 et WHEAR/VIVITSI//WHEAR (2, 3, 4 et 14,
respectivement). Ces lignées d’élite pourraient constituer la base
de reproduction pour la résistance durable dans le blé. La
résistance identifiée pourrait également être incorporée dans
des milieux de haut rendement.
