Production of disease-free papaya planting materials of known sex for commercial fruit production

Papaya (Carica papaya L.) is a medium sized fruit crop with a potential to produce fruits throughout the year. The ripe fruits, which are very rich in vitamins A and C, are popularly used for dessert or processed into jam or wine. Due to its nature as a single stemmed tree it can be economically produced in any size of land from kitchen gardens to large plantations. Papaya producers and researchers encounter some very serious challenges. These include unreliable methods of picking the required sex of seedlings at planting time, lack of disease-free planting materials, lack of improved varieties and devastating diseases that are difficult to control. Some immediate and long term remedies need to be sought to save this crop from extinction. The goal of this research is to contribute to efforts to eradicate poverty and hunger in papaya producing regions through improvement of fruit yield and quality. It will address some current production constraints especially production of disease-free papaya seedlings through in vitro culture of merisematic tissues and micro grafting.
La papaye (Carica papaya L.) est une culture de fruits de taille moyenne avec un potentiel à produire des fruits toute l’année. Les fruits mûrs, qui sont très riches en vitamines A et C, sont couramment utilisés pour le dessert ou transformés en confiture ou au vin. En raison de son caractère unique, d’arbre à une tige, il peut être économiquement produit dans toutes les dimensions de la terre de jardins potagers et les grandes plantations. Les producteurs de papaye et les chercheurs rencontrent quelques défis majeurs. Il s’agit notamment de méthodes fiables pour choisir le sexe des plants nécessaires au moment des semis, le manque de matériel végétal exempt de maladies, le manque de variétés améliorées et des maladies dévastatrices qui sont difficiles à contrôler. Certains remèdes immédiats et à long terme doivent être recherchées pour sauver cette culture de l’extinction. Le but de cette recherche est de contribuer aux efforts visant à éradiquer la pauvreté et la faim dans les régions productrices de la papaye par l’amélioration de la production de fruits et de qualité. Il abordera certaines contraintes de production actuels notamment la production de plants de papaye intact de la maladie grâce à la culture in vitro de tissus merisematic et micro greffe.

"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 agronomy".
