Breeding Cultivars for Resistance to the African Sweetpotato Weevils, and in Uganda: A Review of the Current Progress.

In sub-Saharan Africa, sweetpotato weevils are the major pests of cultivated sweetpotato, causing estimated losses of between 60% and 100%, primarily during dry spells. The predominantly cryptic feeding behavior of spp. within their roots makes their control difficult, thus, host plant resistance is one of the most promising lines of protection against these pests.

Decision tree scoring system to guide selection for consumer preference in sweetpotato breeding trials.

Background: Previously, a lexicon and protocol for quantitative descriptive analysis (QDA) was established for the Uganda sweetpotato breeding program. The implication of QDA scores for priority sensory attributes on consumer preference should be determined to interpret results efficiently and make decisions effectively. The present study aimed to develop a gender-responsive decision tree to obtain an overall sweetpotato eating quality score to facilitate demand-led targeted breeding selection.
