Sensory Evaluation of Cycle 8 Taro Lines

In its effort to support sustainable growth of Samoa’s taro export market, SROS is currently involved in the project ACIAR PARDI/2011/004 – ‘Developing a clean seed system for the market-ready taro cultivars in Samoa’, funded by the Pacific Agribusiness for Development Initiative (PARDI).
SROS’s role in the project are as followed:
  • Conduct field trials on site using appropriate experimental design for sampling of corms for sensory and nutrient analysis
  • Screen new varieties for sensory and nutrient content and partial processing

Phase 1 started in February 2013 with the establishment of the field trials for the nine new taro lines (seedlings) from Cycle eight with Samoa 1 and Samoa 2 as controls. Plant agronomic details along with corm evaluation data was collected for eight months and completed with the sensory evaluation exercise which took place on Friday 11th October 2013.


The Honorable Prime Minister and members of the Organic Farming Advisory Committee were part of the panel of assessors who evaluated the taro lines mainly for taste to determine which lines continue on to Phase two. Phase two will include the replanting of selected taro headsets before undergoing the final sensory and nutritional evaluation upon harvest.
Taro used were harvested at 8 months and for each variety, the taro was uniformly cut, cooked at its appropriate cooking time and cooled before presented to the participants for evaluation.
Results from the evaluation were statistically analysed and four out of nine lines were considered good enough to go through to Phase 2. At the end of Phase two another sensory evaluation exercise will be conducted again for a final selection of the best taro lines (taste and yield) for nutritional evaluation and recommendation for mass multiplication.
