Evaluación de la Resistencia a la Sarna Polvosa en Genotipos de Solanum Phureja Bajo Condiciones Controladas a Partir de Tubérculos Semilla

Abstract: RESUMENSe realizó un bioensayo con 88 genotipos de Solanum phureja para evaluar la respuesta a la sarna polvosa de la papa. Para la obtención del material vegetal, se sembraron tubérculos en bolsas plásticas de 3 kg de capacidad. Cada planta fue inoculada a los 25 días después de siembra, con una aplicación directa a la raíz de 10 g de suelo infectado a una concentración de 7 x 10 6 quistosoros. Después de los 50 días de la inoculación, en estado de floración, se observó la presencia de agallas en raíces. Las … Show more

“…tuberosum Group Phureja contains diploid genotypes with short day adaptations and lack of tuber dormancy [27,28] and has a biodiversity center in the south of Colombia [29]. This group is an important commodity for small-scale farmers [30] and constitutes important germplasm with prospective use in potato breeding programs, providing a source of resistance to late blight and powdery scab [31,32], and high-quality nutritional value [33,34]. Recent studies have characterized late blight resistance [31], frying quality at harvest [35], sugar contents [36], hydroxycinnamic acid contents [37] and anthocyanidin contents in tubers [38].…”
