#Early blight resistant tomato varieties trial

Mountain Magic F1 (Medium)- The most blight resistant tomato we’ve ever seen and the only variety to come through our blight trial unscathed. The sweet tasting fruits are produced in abundance and taste absolutely delicious. Losetto (Cherry) - Resistance to blight is one of the major benefits of this cascading ‘bush’ tomato. Bred for outdoor growing but can be grown at home indoors too! Indeterminate. The collection contains 1 plant each of the following varieties:Ĭrimson Crush F1 (Large)- As well as being resistant to blight this variety provides high yields of great tasting tomatoes weighing up to 200g/4.5lb. Whether outside in the garden or indoors in the greenhouse, we know you will enjoy harvesting these delicious varieties well into the autumn without the fear of blight.The collection contains 3 x 9cm potted plants which all have strong disease resistant qualities. These modern hybrids are all bred for their great taste and unique blight resistance.

Bajo las condiciones del estudio en comparación con la escala de valores de la resistencia, pertenece a una variedad moderadamente resistente con genes de resistencia horizontal a dicha enfermedad fúngica.

La variedad comercial (Santa Cruz Kada Gigante), presentó el porcentaje de infestación promedio (50%) más bajo al ataque del tizón tardío durante la etapa de evaluación desde la inoculación hasta las 120 horas a partir de ahí los foliolos de esta variedad también alcanzó el máximo de infestación. La metodología aplicada fue diseño al azar, seis tratamientos y cinco repeticiones, el experimento consistió en recolectar foliolos sanos de cinco variedades mejoradas y una variedad local de tomate desinfectar e inocular en ambos sitios de la nervadura central de la hoja con Phytophthora infestans con una concentración de conidios 1x10^7/ml en cajas Petri. Para estimar el porcentaje de infestación se registró desde el momento de inoculación hasta la máxima infestación, con una frecuencia de 8 horas hasta la 168 horas. La evaluación se realizó sobre el porcentaje de infestación en foliolos de tomate. Para responder a los bajos rendimientos (económicos y de cosecha) provocados por las enfermedades que atacan al tomate, se considera utilizar variedades de tomates resistentes al tizón tardío (Phytophthora infestans) de tomate (Lycopersicon esculentum Mill) y papa (Solanum tuberosum). A comparison of the study conditions to the scale of resistance values shows it must belong to a moderately resistant variety with horizontal resistance genes to this fungal disease. After 120 hours, the leaflets of this variety also reached maximum infestation.

The commercial variety (Santa Cruz Kada Gigante) presented the lowest average infestation rate (50%) during the evaluation stage from time of inoculation up until 120 hours. After collection, the leaflets were disinfected and inoculated in petri dishes on both sites of the midrib with Phytophthora infestans at concentrations of 1 x 107 conidium/mL. The experiment consisted of collecting healthy leaflets from five improved varieties and one local variety of tomato. The methodology applied was at random and included six treatments and five replications. The percentage of infestation was recorded every eight hours from the time of inoculation until maximum infestation was reached. The evaluation of the percentage of infestation was performed with tomato leaflets over a 168 hour period. In order to respond to the low economic and harvesting yields caused by diseases that attack the tomato, we considered using tomato varieties resistant to late blight (Phytophthora infestans) of tomato (Lycopersicon esculentum) and potato (Solanum tuberosum).
