“…For example, a variety with low mealiness would be desired for mashed potato (usually prepared for children), while the reverse would be true for chips preferred by the youth. 28 More research is therefore required to identify optimal mealiness for varying products to target the specific segmented demand. However, mealy and good smell were considered nice to have characteristics, thus underscoring their importance.…”

BackgroundPotato varieties have diverse biophysical characteristics, so it is important for breeders to have the capacity to choose those that meet the preferences of end users, such as mealiness, firmness, potato taste; among others. Combining user preferences with descriptive information on the sensory characteristics of boiled potatoes can contribute to the improvement of consumer‐driven varieties. This study aims to factor in the preferences of end users to improve the prospects for varietal acceptance, adoption, and discrimination of genotypes in potato breeding.ResultsThe priority quality traits of the boiled potatoes were determined by evaluating gender and livelihood using the G+ tool. Potato genotypes were discriminated by penetration and the procedure was repeatable between cooking replicates at 40 min of cooking. Instrument‐based texture parameters, such as penetration peak force (hardness/firmness) and area (area under curve representing energy needed to penetrate) of boiled potato tubers, are significantly associated with sensory attributes such as fracturability and hardness in mouth. An attempt to discriminate genotypes using NIRS revealed that the average performances observed of the calibration for yellow color (r2 = 0.70), homogeneity of color (r2 = 0.48), moisture in mass (r2 = 0.40) as well as uniformity of texture (r2 = 0.56), suggested that these models could be used for initial breeding screening purposes.ConclusionsThe acceptance traits of the boiled potato can be integrated in the potato breeding program/product profile. NIRS shows great potential to predict potato color. The NIRS models are also promising for predicting some texture attributes.This article is protected by copyright. All rights reserved.

Public breeding programs are pushing to implement demand-led breeding to increase variety adoption, while tackling multiple challenges for increased production under climate change. This has included the improvement of variety target product profiles involving multiple stakeholders. A special case involves the unexpected and rapid spread of the Shangi potato variety in Kenya. This variety was not an especially outstanding variety and the levels of its traits did not exceed the expected thresholds defined in the target product profile for table potato in East Africa. By examining the customer segments looking at gender but also social contexts of smallholder and disadvantaged farmers such as access to markets, inputs, and labor, it became apparent that ready availability of potatoes for consumption, processing, or planting was of prime importance. Given the storage and market constraints, Shangi's very short dormancy, which had been assumed to be a negative trait for farmers, women cottage processors and consumers, was actually meeting the needs for available product and planting material. Consequently, this provided these groups increased control over their productive activities. The case study presented here analyzes different components of potato variety change in Kenya. It explores the challenges and tradeoffs faced by public sector breeding programs and how gender analysis from a broader inclusion perspective can uncover the underlying causes of varietal adoption. Focusing on the Shangi potato variety, the case study reveals a series of lessons learned that have re-shaped the definition of breeding priorities.
