Abstract
With the aim of improving income and nutrition of indigenous highland people in Papua and West Papua provinces of
Indonesia, trials involving introduced and local sweetpotato (Ipomoea batatas L.) cultivars were conducted in the Baliem
Valley and Arfak Mountains (Minyambouw), Indonesia. Tuber yield and other agronomic traits, chemical content and
sensory traits for 17 introduced and three local sweetpotato cultivars were evaluated. Total tuber yield varied from 7.4 to
20.8 Mg ha
–1
in the Baliem Valley and from 1.9 to 14.4 Mg ha
in Minyambouw. The introduced cultivars produced
higher yields than the local cultivars in both regions. Cultivar Papua Pattipi produced the highest yield in the Baliem
Valley, while Sawentar produced the highest yield in Minyambouw. Cultivars varied in dry matter, protein, and betacarotene.
Worembai
was best for tuber flesh colour,
taste, texture and sweetness in the Baliem Valley,
while Helaleke
and
Papua Salosa scored highest for all sensory traits in Minyambouw.
Introduced sweetpotato cultivars adapted well to
both
areas. In order to reduce malnutrition and increase income, it is important to grow several sweetpotato cultivars in
each
food garden, including high yielding cultivars and those with specific nutritional traits, such as high protein, provitamin
A
and anthocyanins.
