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 the theme of Crop Improvement
Mass propagation of selected papaya planting materials through shoot tip culture in Kenya
Abstract:
The objective of this study was to optimise media conditions in
order to develop an efficient plantlet regeneration system of
papaya planting materials. Twelve combinations of different
levels of BAP (0.1, 0.3, 0.5 & 0.7mg/L) and NAA (0.05, 0.1 &
0.2mg/L) were used for shoot regeneration. The highest rate
of shoot multiplication was recorded in 0.5mg/L BAP combined
with 0.1 mg/L NAA. On the other hand, 0.1mg/L BAP combined
with 0.05mg/L NAA produced the longest shoots in the three
local papaya varieties. 2.5mg/l IBA induced about 85% of the
shoots to root. Thus, an efficient plantlet regeneration system
for Kenyan papaya through shoot tip culture was successfully
developed.
L’objectif de cette étude était d’optimiser les conditions du milieu
afin de développer un système efficace de régénération des
plantules de matériel de plantage de papaye. Douze
combinaisons de différents niveaux de BAP (0,1 ; 0,3 ; 0,5 et
0,7 mg / L) et NAA (0,05 ; 0,1 et 0,2 mg / L) ont été utilisées
pour la régénération des pousses. Le plus haut taux de
multiplication des pousses a été enregistré en 0,5 mg / L de
BAP associé avec 0,1 mg / L d’ANA. D’autre part, 0,1 mg / L
de BAP associé à 0,05 mg / L d’ANA a produit les plus longues
pousses dans les trois variétés locales de papaye. 2.5mg / l de
IBA ont induit environ 85% des pousses à la racine. Ainsi, un
système efficace de régénération des plantules de la papaye
kenyane par la culture des bouts de pousse a été développé
avec succès.
