Prüfung verschiedener Erbsentypen auf deren Krankheitsanfälligkeit, Biomasse und Kornertrag

Summary

Generally, purple-flowered peas are considered to be less susceptible to soil-borne diseases and pests than white-flowered peas. Besides, forage peas usually produce more aboveground biomass and less grain yields in comparison to grain peas. Tolerance to soil-borne diseases, above- and belowground biomass and grain yields of two white-flowered (forage and grain pea, respectively) and one purple-flowered (forage pea) pea were examined in a field experiment in Bavaria, Germany.
Purple-flowered peas had neither obvious higher tolerance to soil-borne diseases nor more biomass yield compared to white-flowered peas. Furthermore, the grain yields in this experiment were extremely low and there was no significant difference between the two types. A possible cause could be the unsuitable weather conditions, which caused an increased disease pressure and resulted in low grain and biomass yields. Hence, it can be assumed purple-flowered peas are generally not less susceptible to soil-borne pests than white-flowered peas.
