“…CIP has adapted and recommends participatory varietal selection using mother and baby trials that include a gender dimension for trait preferences (De Haan et al 2019;Mudege et al 2017). The method consists of a series of trials conducted in multiple farmers' fields under local management practices (baby trials) and a demonstration trial that is managed centrally and with recommended agronomic practices (mother trial).…”

Root and tuber crop breeding is at the front and center of CIP’s science program, which seeks to develop and disseminate sustainable agri-food technologies, information and practices to serve objectives including poverty alleviation, income generation, food security and the sustainable use of natural resources. CIP was established in 1971 in Peru, which is part of potato’s center of origin and diversity, with an initial mandate on potato and expanding to include sweetpotato in 1986. Potato and sweetpotato are among the top 10 most consumed food staples globally and provide some of the most affordable sources of energy and vital nutrients. Sweetpotato plays a key role in securing food for many households in Africa and South Asia, while potato is important worldwide. Both crops grow in a range of conditions with relatively few inputs and simple agronomic techniques. Potato is adapted to the cooler environments, while sweetpotato grows well in hot climates, and hence, the two crops complement each other. Germplasm enhancement (pre-breeding), the development of new varieties and building capacity for breeding and variety testing in changing climates with emphasis on adaptation, resistance, nutritional quality and resource-use efficiency are CIP’s central activities with significant benefits to the poor. Investments in potato and sweetpotato breeding and allied disciplines at CIP have resulted in the release of many varieties some of which have had documented impact in the release countries. Partnership with diverse types of organizations has been key to the centers way of working toward improving livelihoods through crop production in the global South.

“…As such, targeted breeding for end-user preference has been proposed to address this challenge. 3,4 Furthermore, promoting potato varieties without considering the needs of disadvantaged social groups, such as women and youth, who are typically the target beneficiaries of public breeding programs, may reduce acceptance and adoption rates. For example, one of the persistent disparities between male and female farmers is the lower adoption of modern varieties by households with female heads than by households with male head.…”

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.

Determinants Influencing Selection of Potato Varietal Technology and the Role of Gender in Farm Decisions in Bhutan

Potato is a primary food and cash crop in Bhutan. The adoption of new varieties has faced some challenges. To address this situation, farmers’ needs and priorities were investigated through varietal demonstration and a field survey in seven of the main potato-growing districts of Bhutan. The role of gender in farm decisions and operations in relation to potato farming was also assessed. Nine quality determinants significantly ( χ 2 = 376.54, P < 0.001) influenced farmers’ selection of potato varieties. These determinants, in order of their relative preference, were as follows: high productivity (15.5% by weight of mean rank), high market value (13.4%), red-skinned (12.7%), marketability (11.6%), large tubers (11.3%), late-blight resistant (11.3%), micronutrient content (8.8%), short-duration (8.3%) and good taste (7.2%). Potato productivity (yield) and preference vote data were significantly correlated ( R = 0.395, P < 0.01) for female farmers but not for male farmers. Similarly, the involvement of female farmers in farm decision-making processes was significantly ( P < 0.001) higher than when compared with their male counterparts. However, both genders were equally involved in physical farm operations. Bhutanese potato cropping is highly driven by commercially driven (market) preferences such as yield, colour and size as opposed to subsistence preferences such as micronutrient content. Understanding farmers’ priorities during the development of new potato variety is critical for varietal selection for adoption. Furthermore, understanding the role of women in farm decision-making processes is crucial for adoption of new varietal technology in potato production. These findings may serve as an evidence-based insight to guide research and policy interventions in Bhutan and in similar agroecologies.
