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"
Combining ability analysis of quality protein maize (QPM) and non-PM inbred lines for kernel quality and some agronomic characteristics
Abstract:
The biggest population in Zimbabwe depend on maize as a
source of carbohydrates, yet it is deficient in protein and
therefore makes the population prone to protein malnutrition.
Quality Protein Maize (QPM) has double the amount of lysine
and tryptophanand therefore desirable suitable to combat
possible protein malnutrition. The Zimbabwe maize research
programme is currently using QPM inbred lines whose
combining ability for grain quality and agronomic traits has not
been previously tested and validated. In this study, combining
ability analysis was conducted to identify appropriate QPM
donor inbred lines for use in the development of new QPM
inbred lines and the conversion of non-QPM open pollinated
varieties (OPVs) and inbred lines to QPM. From the study, the
inbred lines CZL082 and CML511 are recommended for use
as donors in the development of new QPM inbred lines and the
conversion of non-QPM inbred lines and OPVs to QPM by
the national maize research programme in Zimbabwe.
La plus grande population du Zimbabwe dépend de maïs comme
source de glucides, toutefois déficient en protéines et de ce fait
rendant la population sujette à la malnutrition protéique. Le maïs
de qualité en protéines (QPM) a une concentration double de
lysine et tryptophanande et est ainsi souhaitable et convenable
pour lutter contre la malnutrition protéique possible. Au
Zimbabwe, le programme de recherche sur le maïs utilise
actuellement les souches pures de QPM dont la capacité de
combiner la qualité du grain et les caractères agronomiques
n’a pas été préalablement testée et validée. Dans cette étude,
l’analyse de l’aptitude à la combinaison a été menée pour
identifier les souches pures de donneur QPM appropriées pour
une utilisation dans le développement de nouvelles lignées pures
de QPM et la conversion des variétés de non-QPM à
pollinisation libre (OPVs) et des lignées pures en QPM. Dans cette étude, les lignées pures CZL082 et CML511 sont
recommandées pour les utiliser comme donneurs dans le
développement de nouvelles lignées de QPM et la conversion
des lignées pures de non-QPM et OPVs en QPM par le
programme national de recherche sur le maïs au Zimbabwe.
