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"
Pyramiding Fusarium root rot resistance genes and validation of SSR PVBR87 in common bean
Abstract:
This study determined effectiveness of pyramided Fusarium
root rot (FRR) resistance genes and validated association of
SSR PVBR87 marker with FRR resistance in common bean.
A double cross (DC) involving four resistance sources was
used to accumulate FRR resistance genes into one background.
The DC F1 and each resistant line were crossed to two
susceptible cultivars. Parents, F1 and F2 populations were
subjected to FSP-3 in a screenhouse. Two single cross (SC) F2
populations were screened with SSR PVBR87 marker. Fiveparent
crosses performed better than single crosses. SSR
PVBR87 marker showed association with FRR resistance in
the two SC F2 populations.
Cette étude a déterminé l’efficacité des gènes pyramidés de
résistance de la putréfaction de racine de Fusarium (FRR) et
a validé l’association du marqueur SSR PVBR87 avec la
résistance de FRR dans le haricot ordinaire. Un double
croisement (DC) impliquant quatre sources de résistance a été
employé pour accumuler des gènes de résistance FRR au
second plan. Le F1du double croisement DC et chaque lignée
de résistante ont été croisés à deux cultivars sensibles. Les
parents et les populations F1 et F2 ont été soumis à FSP-3 dans
un milieu d’observation. Deux populations F2 de simple croix
(SC) ont été examinées avec le marqueur SSR PVBR87. Les
croisements de cinq parents se sont exécutés mieux que les
croisements simples. Le marqueur SSR PVBR87 a montré
l’association avec la résistance FRR dans les deux populations
F2 de SC.
