“…El uso de tubérculos libres de enfermedades permite alcanzar el máximo de potencial productivo (Frost et al 2013). En países con niveles masivos de producción comercial, el uso y flujo constante de semillas de papa de alta calidad es imperativo (Guenthner et al 1991).…”

Bajos niveles productivos de papa en el Perú y otros países de la región son atribuidos al poco uso de semilla de calidad y reciclaje de tubérculos contaminados. Por ello hay consenso en la necesidad de incorporar tecnologías de producción de semilla de calidad que sean efectivas y eficientes pero que sean consecuentes con la realidad de la papa en Latinoamérica. Este estudio examinó un sistema tecnológico de producción de semillas desarrollado por la compañía americana CETS de Wisconsin. Este sistema usa cámaras de crecimiento llamadas fitotrones donde los parámetros de crecimiento son todos controlados automáticamente. Las plantas pueden producir mini-tubérculos entre 60 y 70 días, permitiendo hasta seis cosechas por año. Para validar el uso de esta tecnología diez variedades nativas de ocho especies cultivadas de papa fueron usadas. Los resultados demostraron que las plantas completaron sus ciclos fenológicos y fisiológicos dentro de los rangos de tiempos establecidos. La producción de tubérculos fue variable, en algunos casos fue muy alta (Solanum x ajanhuiri) pero en otros fue solo moderada (S. phureja). En resumen, el sistema de CETS ofrece una posibilidad para la producción de semilla de calidad en variedades de papas nativas de la región. Este sistema podría también tener impacto en otras áreas como conservación de biodiversidad, mejoramiento genético e investigación básica.

Valuing Disease Prevention in a Vegetatively Propagated Annual Crop: Benefits From the Montana Seed Potato Certification Program

2020

We examine the economic costs of potato virus Y (PVY) and benefits to commercial potato growers from using screened seed. To do so, we use a quantile regression model to explore disease spread. We use this model to predict disease prevalence and corresponding losses in commercial potato operations with and without a screening and certification program in place. Our analysis suggests that this screening is very important; the amount of PVY in seed in the summer test is the strongest predictor of PVY in the winter test of the variables in our model. The amount of PVY in the seed can have major effects on commercial potato grower revenues and profitability. Using data and models from Idaho, a major purchaser of Montana seed, we estimate the annual benefit from Montana’s program to Idaho to average $205 per acre or $22 million for the state.

Integrated Control of Potato Pathogens Through Seed Potato Certification and Provision of Clean Seed Potatoes

2013

Long-term data sets are rare in agriculture, and the impact of plant diseases on food production is challenging to measure, which makes it difficult to assess the impact of policy changes or research-based disease control efforts. Despite this challenge, it is clear that one of the largest impacts of biological research on food security over the past century has been in production of vegetatively propagated fruit and vegetable crops such as potato. The yield and quality of these crops is higher in countries that have effective plant propagation and certification systems. Of these systems, seed potato production and certification is among the most developed. We analyzed a dataset from a century-old seed potato certification program in Wisconsin to assess the efficacy for potato disease control and the cost of this program compared to other disease control and potato production costs. We found that over the past century, certification has gradually reduced the incidence of mechanically transmitted vascular potato pathogens that lack insect vectors to undetectable levels, and much of this reduction occurred prior to the use of tissue culture and the development of immunoassays. Rejection of seed lots from certification is now rare, with Potato virus Y (PVY), a virus spread nonpersistently by numerous, noncolonizing aphid species, and farmer errors being the main causes of rejection. PVY level increases occurred in 2000, coincident with the first detection of a new invasive vector, soybean aphid, in the Midwest. The increased PVY incidence was more pronounced in varieties that exhibit mild foliar symptoms. Starting in 2004, a decrease in PVY incidence occurred following comprehensive science-based changes to early generation seed potato production. The cost of the certification program has not increased in two decades, and the fees charged are comparable to those in 1913. The cooperative nature of the seed potato certification program has contributed to its sustainability across generations. However, looming soilborne disease problems are not easily addressed by certification and will likely cause significant challenges in the future.
