Yams (Dioscorea spp., Dioscoreaceae), grown either for their starchy tubers or medicinal properties, are important crops in the tropics and subtropics. Yams broaden the food base and provide food security and income to over 300 million people. They are vegetatively propagated and comprise both di...

For a mixture of reasons certain tropical crops which are important as primary or secondary food staples are relatively underresearched. The modem tools of molecular and cellular biotechnology offer the opportunity not only to make substantial gains in our knowledge of these crops, but also to ov...

Cassava, yam, and plantain are staple food crops essential to food security in the humid and Sub-humid tropics of Africa. However, these crops have long growth cycles, high perishability and slow multiplication rates of propagation materials, and they are subject to a number of biological stresse...

Wild relatives of cassava (Manihot spp.) and yam (Dioscorea spp.) have many attributes of importance to the genetic improvement of the cultivated species. Some crosses between cassava and its wild relatives have led to poly ploids (crosses to M. />laziovii and M. epruinosa) and resistance to two ...

Plant breeders face the difficult task of having to select for traits that are often under complex genetic control and subject to edapho-climatic influences. Electrophoresis of protein extracts from plant tissue, using different kinds ofsupport media and buffer systems, allows separation of the m...

Plant reproduction is a core process in plant breeding. For decades, one can even say for centuries, plant reproductive biology has largely been a matter of observation, description, and philosophical speculation. Only in the last two decades has it entered the experimental phase, and it is in th...
