| dc.description.abstract | The demand for potato varieties (Solanum tuberosum L.) with acceptable yield and
processing characteristics is increasing in Kenya. However, most potato varieties and
promising clones have not been adequately evaluated. In this study, three advanced potato
clones (393385.47, 393385.39 and 391691.96) and five established Kenyan varieties (Tigoni,
Desiree, Dutch Robyjn, Kenya Karibu and Kenya Sifa) were evaluated for processing into
fresh and frozen French fries. All the 8 cultivars had acceptable physical tuber
characteristics, dry matter content (≥ 20 %) and specific gravity (≥ 1.070). A linear positive
correlation was established between tuber specific gravity and dry matter content (r= 0.97).
All the cultivars made highly acceptable French fries (freshly prepared or frozen), with
clones 393385.47 and 393385.39 having lower acceptability scores. The five varieties (Tigoni,
Desiree, Dutch Robyjn, Kenya Karibu and Kenya Sifa) and clone 391691.96 can also be used
for processing fresh or frozen chips to supplement variety Tigoni that is currently the most
preferred for processing in Kenya. This will reduce over reliance on a single potato variety
for this rapidly expanding industry, and thus safeguard availability and quality of raw
materials. | en_US |
