A field experiment was conducted on thirteen (13) Musa hybrids derived from 4n x 2n crosses, three (3) checks and two (2) plantain landraces to evaluate phenology, growth characteristics and yield performance in a humid agro ecological zone of Nigeria. Fifteen (15) phenotypic characters were sign...

Banana germplasm collections serves as a source of useful genes for banana breeding. However, insufficient and/or inaccurate information on the ploidy level of the germplasm renders its utilization in breeding difficult. The objective of this study was to determine and validate the ploidy level o...

In the last 45 years, IITA has played a pivotal role in the genetic improvement of cassava for resourcepoor farmers in sub-Saharan Africa (SSA). More than 400 varieties have been developed that are not only high yielding but also resistant to diseases and pests. Many of these improved varieties h...

African food system Yam (Dioscorea spp.) is a multispecies, clonally propagated crop cultivated for its starchy tubers. About 10 species are widely cultivated around the world, but only D. rotundata, D. alata, and D. cayenensis are the most widely cultivated species in West Africa, accounting for...

In Thailand cassava breeding is the responsibility of the Rayong Field Crops Research Center of the Department of Agriculture (DOA), and of Kasetsart University (KU). From 1975 to 1992, six cultivars have been released for industrial use, i.e. Rayong 1, Rayong 3, Rayong 60, Rayong 90, Sri Racha 1...
