SASHA Brief 2014: Getting Sweetpotato Varieties to Farmers Faster: The Accelerated Breeding Scheme (ABS)

The shortage of high quality planting material and lack of improved orange fleshed sweetpotato (OFSP) varieties is the most important constraints to sweetpotato production in Sub-Saharan Africa (SSA). Conventional breeding is time consuming hence need for alternative technology such as Accelerated Breeding schemes (ABS). This approach documents solid evidence generated in Peru and Mozambique for efficiently reducing the time (8 to 4-5 years) from crossing to varietal release within a given sweetpotato population. In conclusion ABS is enhancing the efficiency of selection within a given population. Further, combining ABS and Heterosis exploiting breeding schemes (HEBS) appear the best tools offered by selection theory to enhance in this and the next decade to applied breeding of clonally propagated crops.
