説明
<jats:title>Abstract</jats:title> <jats:p>Selection activities in plant breeding can be carried out only if there is variation in the plant’s genetic materials. Plant volatile compounds are media for interaction between plants and insects, making them potential to be used as a selection parameter in resistant plant breeding programs against insect pests. This study aimed to determine the diversity of chili pepper (<jats:italic>Capsicum</jats:italic> spp.) volatile compounds and to explain its relationship to the main insect pests of chili pepper. The research was carried out at IVEGRI’s research station in Lembang, West Java, Indonesia from March to September 2020. The treatment involved 34 chili pepper varieties. The observation parameters included profiles of volatile compounds measured using GC-MS and incidence of main insect pests (thrips, worms, and fruit fly). The results showed that 87 volatile compounds detected, eight of them, i.e. 3,6-Nonadien-1-ol, (E, Z)-,β-Ocimene, trans-β-Ocimene, 3-Allylcyclohexene, 2,4,6-Octatriene, 3,4-dimethyl-, Neo-allo-ocimene, 1-Octanol and 2-Methylanisole showed a high level of diversity among the chili pepper varieties tested. The results of a simple correlation test showed positive and negative correlations between eight volatile compounds and pest incidence, with a range from -6.80 to 0.87. The relationship between these volatiles compounds and pest incidence will be subject to a further discussion.</jats:p>
