Krankheitsanfälligkeit und Biomasseertrag verschiedener Erbsentypen in einem Gefäßversuch

Summary

Generally, purple-flowered peas are assumed to be less susceptible to soilborne pests. Ten peas were compared regarding tolerance to soilborne diseases and above- and belowground biomass yield on two soils with soil fatigue and a cultivation substrate as a control. In the pot experiment, five purple-flowered and five white-flowered grain and forage peas were tested.
Purple-flowered peas had no higher tolerance to soilborne diseases compared to white-flowered peas. Forage peas were not less susceptible to soilborne diseases compared to grain peas, too. But purple-flowered peas showed a lower decrease in biomass yield among others due to a lower reduction for field emergency on soils with soil fatigue. This may cause a higher tolerance to soilborne pests before pea field emergence and/or a lower susceptibility to a rougher seeding bed.
