Abstract

Currently, there are no studies on the cultivation of quinoa (Chenopodium quinoa) in Peru related to the reaction ofMeloidogynespp. Thisstudy aimed to evaluate the reaction of five quinoa cultivars (‘Salcedo INIA’, ‘Choclito’, ‘Huariponcho’, ‘Negra Collana’, and ‘Kcancolla’)toMeloidogyne arenaria, Meloidogyne incognita,andMeloidogyne hapla. The experiment was carried out using a completely randomizeddesign, with five quinoa cultivars and three species ofMeloidogynespp. with six repetitions. Quinoa plants were kept in a mesh house andplaced in polyethylene bags with 3,000 dm³ of sterile soil inoculated with 5,000 eggs + juveniles (J2). After 90 days of inoculation, thenumber of nematodes per gram of root, number of galls, and the reproduction factor (final population/initial population) were determined.All quinoa cultivars were susceptible toM. incognitaand resistant toM. arenariaandM. hapla,except for ‘Negra Collana’, which wassusceptible toM. arenaria, and ‘Salcedo INIA’ and ‘Huariponcho’, susceptible toM. hapla.

藜麦对不同根结线虫的反应

目前，秘鲁藜麦(Chenopodium quinoa)栽培中还没有与meloidogynespp反应有关的研究。本研究旨在评价5个藜麦品种(“Salcedo INIA”、“Choclito”、“Huariponcho”、“Negra Collana”和“Kcancolla”)对红藜麦(eloidogyne arenaria)、黑藜麦(Meloidogyne incognita)和黑藜麦(Meloidogyne hapla)的反应。试验采用完全随机设计，选用5个藜麦品种和3个藜麦品种。重复六次。将藜麦植株置于网眼棚内，放入聚乙烯袋中，放入3000 dm³无菌土壤，接种5000个卵+幼虫(J2)。接种90 d后，测定每克根线虫数、虫瘿数和繁殖系数(最终种群/初始种群)。所有藜麦品种均对toM敏感。不认识的和抵抗的汤姆。arenariaandM。除了“Negra Collana”之外，其他都是很容易受影响的。沙棘菌、沙棘菌和花蓬草对toM敏感。差异。
