Chili pepper genotypes assay approach for resistance to Aphis gossypii (Hemiptera: Aphididae)

The cotton aphid (Aphis gossypii), is one of the most devastating insect pests for chili pepper that damages crop and transmits several viruses. Thus far, there no commercial cultivar with effective resistance to aphids (CA). present study aimed develop a reliable practical screening protocol in peppers tropical areas. Three no-choice test methods i.e., seedling cage, detached leaf, clip cage tests have been developed. experiment was conducted randomized complete block design (RCBD) four replications greenhouse at Gunung Putri, Bogor, West Java, Indonesia. Seven genotypes belong species Capsicum annuum L. provided by Department Agronomy Horticulture, IPB University, Indonesia were used this study. Chili observed through number progeny, fecundity among genotypes. Two consistently showed low infestation while other highest three methods. All high heritability value (90%–91%), indicating evaluated could be determine correlation between leaf significant (r = 0.84, P ? 0.05). Therefore, as assay CA infestation. These information will helpful development resistant cultivars future.
