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.
Effectiveness of Macropropagation Technology in Production of Disease Free Banana Seedlings in Central and Eastern Kenya
Abstract:
Banana (Musa spp.) is one of the most important food crops
that contribute to the food security of the majority small holders
in Kenya. However, due to diseases, banana production has
not reached its full potential. Fusarium wilt caused by Fusarium
oxysporum f. sp. cubense (Foc); black and yellow sigatoka
leaf spot caused by Mycosphaerella fijiensis and
Mycosphaerella musicola respectively, weevils (Cosmopolites
sordidus) and plant parasitic nematodes have been the major
diseases affecting banana seedlings. In addition, banana
Xanthomonas wilt (BXW) caused by the bacterium
Xanthomonas vasicola pv. musacearum is a disease that rapidly
destroys plantations. Most of these diseases are spread by use
of infected planting material. Macropropagation is a cost
effective seedling production technology which can be
implemented with little capital and skill to provide planting
material. The study was carried out to determine the potential
of the the technology to produce healthy banana seedlings. From
the study, the macropropagation technique has potential for
banana seedlings multiplication only if the mother corms were
healthy.
Le bananier (Musa spp.) est l’une des cultures vivrières les
plus importantes qui contribuent à la sécurité alimentaire de la
majorité des petits agriculteurs au Kenya. Toutefois, à cause
des maladies, la production des bananes n’a pas atteint son
plein potentiel. La fusariose causée par Fusarium oxysporum
f. sp. cubense (Foc), la tache noire et jaune de sigatoka causée
par Mycosphaerella fijiensis et Mycosphaerella musicola
respectivement, les charançons (Cosmopolites sordidus) et
les nématodes parasites des plantes ont été les principales
maladies affectant les semis très jeunes. En outre, le fanage
Xanthomonas de la banane (BXW) causé par la bactérie Xanthomonas vasicola pv. musacearum est une maladie qui
détruit rapidement les plantations. La plupart de ces maladies
se propagent par l’utilisation du matériel de plantation infecté.
La macropropagation est une technologie de production des
semis à un coût efficace, qui peut être mise en place avec peu
de capital et de compétence pour fournir du matériel de
plantation. L’étude a été réalisée afin de déterminer le potentiel
de la technologie pour produire des semis de bananier sains.
D’après l’étude, la technique de macropropagation ne dispose
d’un potentiel de multiplication des semis de bananier que si les
bulbes-mères étaient sains.
