A Genetic Linkage Map of Sweetpotato (Ipomoea batatas (L) Lam) Based on AFLP Markers

Genetic linkage maps of Tanzania and Bikilamaliya sweetpotatoes (Ipomoea batatas (L.) Lam), based on amplified fragment-length polymorphism (AFLP) were developed using a two-way pseudo-testcross. At a LOD score of 5, a total of 656 maternal and 469 paternal markers were ordered in 90 and 80 linkage groups, respectively, covering a …

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 …

Effect of temperature on the development, reproduction and mortality of the sweetpotato weevil Cylas brunneus (Fabricius) (Coleoptera: Brentidae)

The sweetpotato weevil, Cylas brunneus, is a serious insect pest of sweetpotato (Ipomoea batatas (L.) Lam.) in East and West Africa. Knowledge on the influence of temperature on development, reproduction and mortality of this pest is important in understanding its potential population growth and geographical distribution. Such knowledge is a pre-requisite …

On-farm evaluation of the impact of drying and storage on the carotenoid content of orange-fleshed sweet potato (Ipomea batata Lam.)

Drying of orange‐fleshed sweet potato was evaluated under African rural conditions. Three locally built dryers (open‐air sun, tunnel and shade) were tested using Resisto and MGCL01 varieties in Mozambique. Total carotenoid losses were low in all dryers being 9.2% on average. After drying, sweet potato chips were stored in a …

Effect of drying and storage on the degradation of total carotenoids in orange-fleshed sweetpotato cultivars

Orange‐fleshed sweetpotato (OFSP) can be used to tackle vitamin A deficiency, a major public health problem in most developing countries. In East Africa, common ways of using sweetpotato include drying and subsequent storage. The aim of the study was to investigate the impact of drying and storage on the total …
