Rapid Multiplication and Dissemination of Sweetpotato Varieties with High Yield and ß-Carotene Content

The project aimed at reducing food insecurity, poverty and malnutrition among small-scale farmers in eight districts of central Uganda. This was to be achieved through increased multiplication, distribution, production and consumption of sweetpotato varieties that are not only high yielding and virus resistant but also rich in ß-carotene (a precursor …

Diallel analysis of root dry matter content in sweetpotato

There has been much emphasis on breeding for increased sweetpotato storage root yields, but less on the dry matter yield, and its inheritance. High dry matter content (DMC) is associated with consumer preferences, and is important for processing industry. This study was conducted to determine the type of gene action …

Effect of GxE Interaction on Root Yield and Betacarotene Content of Selected Sweetpotato (Ipomoea batatas (L) Lam.) Varieties and Breeding Clones

A multilocational field trial involving nine sweetpotato clones of diverse origins was conducted across four different locations to investigate GxE interaction effects on commercial root yield and beta-carotene pigment content in roots. None of the high-yielding cultivars had satisfactory stability, according to biplots for total root yield based on the …
