Genotype and environmental influence on root quality and shelf life of Philippine sweetpotato.

Philippine sweet potato production is highly seasonal and yields remain low (5 t/ha) in spite of new high yielding varieties. Some drawbacks include poor eating quality and short shelf life. Data on dry matter, starch, sugar and protein contents were recorded on 9 cultivars grown during the wet and dry seasons. Shelf life at room temperature was also recorded over a 3 month period. Dry matter content was highest in V15-70 and was not correlated with starch and sugar contents. Protein content was low, ranging from 2.2 to 3.95%. Fresh roots of OPS99, VSP1 and VSP5 had a short shelf life (<1 month) while others such as V37-151 had a longer shelf life (<3 months).
