| Abstract | Potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), is a key pest of potato and the vector of “Candidatus Liberibacter solanacearum,” the pathogen associated with zebra chip disease. Development of potato cultivars with genetic resistance to potato psyllid would enable cost-effective control of this pest with reduced use of insecticides. To facilitate the development of resistant cultivars, the objective of our study was to screen germplasm accessions of Solanum verrucosum for resistance to potato psyllid. The susceptibility of S. verrucosum germplasm accessions to potato psyllid was highly variable in choice prescreening assays and no-choice performance assays. Compared with the susceptible potato cultivar, ‘Russet Burbank,’ several S. verrucosum populations exhibited strong resistance to potato psyllid. The S. verrucosum accession, PI 195170 was highly resistant to potato psyllid, and is a potential source of genetic resistance for the development of resistant potato cultivars.El psílido de la papa, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), es una plaga clave de la papa y el vector de “Candidatus Liberibacter solanacearum,” el patógeno asociado a la enfermedad de la papa rayada (zebra chip). El desarrollo de variedades de papa con resistencia genética al psílido, permitiría un control costo-efectivo de esta plaga con el uso reducido de insecticidas. Para facilitar el desarrollo de variedades resistentes, el objetivo de nuestro estudio fue probar introducciones de germoplasma de Solanum verrucosum para la resistencia al psílido. La susceptibilidad de las introducciones del germoplasma de S. verrucosum al psílido de la papa fue altamente variable en ensayos de la selección antes de la evaluación, y en el comportamiento de los ensayos de no selección. Al compararlas con la variedad susceptible de papa “Russet Burbank”, varias poblaciones de S. verrucosum exhibieron fuerte resistencia al psílido. La introducción PI 195170 de S, verrucosum fue altamente resistente al psílido y es una fuente potencial de resistencia genética para el desarrollo de variedades resistentes de papa. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
