Abstract

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.
