Greenhouse evaluation of potato seedlings for leaf roll virus resistance

  • J. P. MacKinnon
Article

Summary

A practical greenhouse method of screening potato seedlings for leaf roll virus resistance is described. Infected seedlings could not always be detected by symptoms, but nymphs ofM. persicae recovered virus from inoculated plants and transmitted it toP. floridana. Best results were obtained when recovery tests were made 3 or 4 weeks after seedlings were infected.

P. floridana was more susceptible and provided a better source of virus for aphids than any of the potato seedlings tested. Also, upper leaves of potato seedlings grown from seed or from infected tubers provided a better source of virus than middle or lower leaves from the same plants.

Resumen

Se describe un método práctico de invernadero para seleccionar plántulas de papa por su resistencia al virus que causa la rosca de hoja. Plántulas infectadas no siempre pueden ser identificadas por los síntomas pero las nimfas deM. persicae extraeron el virus de plantas infectadas y lo transmitieron aP. floridana. Se obtuvieron los mejores resultados cuando los ensayos de extracción fueron llevados a cabo 3 o 4 semanas después de la infección.

P. floridana era más susceptible y dió una mejor fuente de virus para los áfidos que todas las plántulas de papa con que se experimentó. También, las hojas las hojas superiores de plántulas de papa obtenidas de semilla o de tubérculos infectados eran mejor fuente de virus que las hojas centrales o bajas.
