Potato virus Y (PVY) infection is one of the greatest challenges to seed potato production in the United States. To determine how cultivar and seed type affect the development of systemic PVY infection, Russet Burbank and Russet Norkotah Colorado 3 cultivars were grown from two types of pre-nuclear seed (i.e., plantlets and minitubers) and Generation 3 (G3) tubers and challenged with PVY strain Wilga (PVY N-Wi ). Systemic PVY infection was measured by assaying spread of virus from the inoculation site to upper non-inoculated leaves. The Burbank cultivar had a lower incidence of systemic PVY infection compared to the incidence of systemic PVY that developed in the Colorado 3 cultivar. Furthermore, Burbank plants grown from G3 tubers had a lower incidence of systemic PVY infection, as compared to Burbank plants grown from plantlets. Together our results indicate that both cultivar and seed type affect the development of systemic PVY N-Wi infections post-inoculation. ResumenLa infección por virus Y (PVY) es uno de los mayores retos en la producción de semilla de papa en los Estados Unidos. Para determinar cómo afecta la variedad y el tipo de semilla al desarrollo de la infección sistémica de PVY, se cultivaron las variedades Russet Burbank y Russet Norkotah Colorado 3 de dos tipos de semilla pre-nuclear (p. e., plántulas y minitubérculos) y de tubérculos de la Generación 3 (G3), y se inocularon con PVY variante Wilga (PVYN-Wi). La infección sistémica de PVY se midió mediante la detección de la dispersión del virus desde el sitio de inoculación hacia las hojas superiores no inoculadas. La variedad Burbank tuvo la incidencia más baja de infección sistémica de PVYen comparación con la incidencia de PVY sistémico que se desarrolló en la variedad Colorado 3. Aún más, las plantas de Burbank originadas de los tubérculos de G3 tuvieron la incidencia más baja de infección sistémica de PVY, en comparación con las plantas de Burbank originadas de plántulas. Juntos, nuestros resultados indican que tanto la variedad como el tipo de semilla afectan el desarrollo de infecciones sistémicas de PVYN-Wi después de la inoculación.

“…Straw mulching has been shown to be an effective method for controlling PVY spread [139,140,141,142]. While increasing nitrogen levels in the soil may impact overall plant growth, it does not significantly reduce the yield loss associated with PVY infections [143].…”

Potatoes are a cornerstone of global agriculture and a fundamental component of diets worldwide, with plant viruses accounting for nearly half of the emerging crop epidemics. Among these, Potato Virus Y (PVY) poses a formidable challenge to potato farming, leading to significant economic repercussions and threats to food security. Understanding the influence of climate on PVY is pivotal in tackling this viral menace. Climatic conditions, including temperature, precipitation, and humidity, play a key role in the behavior of aphids, the primary vectors of PVY, thereby impacting the disease's prevalence in potato fields. With climate change modifying these key weather variables, there's a looming risk of enhanced PVY spread and a shift in its geographical presence. Recognizing and adapting to these climate-induced changes is vital for formulating effective strategies and sustainable practices to counter PVY's effects, safeguarding potato crops from this major viral threat. This analysis delves into the complex dynamics between climate change and PVY, focusing on how changes in weather patterns influence the virus's behavior and impact, with the aim of enhancing our preparedness and response to this agricultural challenge.
