Abstract
The purpose of this study was to determine whether P60 could induce resistance in local Aceh chili varieties to begomovirus and compared with national varieties. This research was conducted at the Experimental Garden and Laboratory of Genetics and Plant Breeding in the Eastern Sector, Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh, from Maret to Juli 2021. This study used a factorial randomized block design. The tested factors consisted of two factors, the main factor (P0 = without giving P60 and P1 = giving P60). The second factor consisted of four local Aceh chili varieties, namely: V1 = Odeng, V2 = Lanyoe, V3 = Super Lamando and V4 = Lamando Lapaben and one national variety, namely V5 = Baja F1 as a comparison variety. The best local variety Aceh Lamando Lapaben for resistance response, incubation period, disease intensity, disease incidence, stem diameter, and crown width. The best local variety Aceh Lanyoe on plant height and dichotomous height parameters. Giving P60 can reduce the percentage of disease incidence 52.00% and slow down the process of emergence of disease symptoms (incubation period) 27.11 DAP. The best treatment treatment combination was the Lamando Lapaben variety, namely 1.41 Umg-1 protein.
