Abstract
La investigación se realizó con los objetivos de evaluar la población final, de G pallida, evaluar el rendimiento, resistencia, tolerancia y susceptibilidad de diez clones de S. tuherosum y seleccionar los clones según los criterios de Cook, se emplearon 10 variedades de papa cultivadas resistentes y tolerantes al G pallida, obtenidas del Banco Nacional de Germoplasma del INIA-Ayacucho, los quistes de G pallida se obtuvieron del laboratorio de Nematología de la Facultad de Ciencias Biológicas de la UNSCH, cada unidad experimental tuvo 0.4 kg/maceta de un sustrato con 1 tubérculo de cada clon, la inoculación y siembra se hizo con 08 tubérculos/semilla de 15 g, sembrando un tubérculo por maceta, 4 sin inóculo (n0) y 4 con inóculo (n1). La población final de G pallida fue baja en los clones 5 y 6; alta en los clones 8 y 10. Los clones inoculados (n1) presentaron 5.56 % menos rendimiento que los no inoculados (n0), el clon 6 muestra mayor diferencia en el rendimiento (18.25%), demostrando que es No tolerante al G pallida, los demás clones son tolerantes. Todos los clones son susceptibles con tres rangos de "I". Según los criterios de Cook, el clon 6 es no tolerante y susceptible.
The research was carried out with the objectives of evaluating the final population of G. pallida; To evaluate the performance, resistance, tolerance and susceptibility of ten clones of S. tuberosum and select the clones according to Cook's criteria, 10 varieties of cultivated potato resistant and tolerant to G pallida were used, obtained from the National Germplasm Bank of INIA- Ayacucho, G pallida cysts were obtained from the Nematology laboratory of the Faculty of Biological Sciences of the UNSCH, each experimental unit had 0.4 kg / pot of a substrate with 1 tuber from each clone, inoculation and seeding was done with 08 tubers / 15 g seed, sowing one tuber per pot, 4 without inoculum (n0) and 4 with inoculum (n1). The final population of G. pallida was low in clones 5 and 6; high in clones 8 and 10. Inoculated clones (n1) showed 5.56% less yield than non-inoculated (n0), clone 6 shows a greater difference in yield (18.25%), demonstrating that it is not tolerant to G pallida, the other clones are tolerant. All clones are susceptible with three "I" ranges. According to Cook's criteria, clone 6 is non-tolerant and susceptible.
