Abstract

Response of six chili varieties to anthracnose disease caused by Colletotrichum acutatum and C. gloeosporioides. Chili is one of the horticultural commodities with high economic value. Chili production is constrained by anthracnose diseases. Losses due to anthracnose can reduce the fruits quality and yields lose. This study aims to determine the resistance of several chili varieties to anthracnose. Genetic material was used six varieties of chili. Ripe chilies were inoculated with two types of Colletotrichum isolates, i.e. C. acutatum and C. gleosporides. The experiment was arranged in a factorial randomized block design with three replications. The first factor were chili varieties: Laris, SSP, Habanero, Cibinong, Ekasari, and Kopay. The second factor was two types of fungal isolates. Observations were made on the incidence and severity of disease due to anthracnose. The results showed that both fungal isolates were effective in causing anthracnose disease in chilies. Habanero was very susceptible to anthracnose. Laris and Ekasari were moderately resistant to anthracnose diseases. These findings are important to develop new Capsicum cultivars that are more adaptive to anthracnose disease.

Abstract

Diversity of fruit flies (Diptera: tephritidae) attracted by me lure in CSG-BG germplasm carambolae plantation. Germplasm Garden (KPN) Cibinong Science Center-Botanical Garden (CSC-BG) is one of the gardens that conserve and utilizes Indonesian local germplasm, one of which is carambolae. The current problem in KPN is the attack of fruit flies (Bactrocera spp.). This study was conducted to determine the diversity of fruit flies in the KPN carambola plantation area. A total of eight traps were placed randomly in the plantation area. Each trap contained 1 mL of methyl eugenol pheromone solution. Identification of fruit flies was carried out based on three morphological differences, they were wings, abdomen, and hind legs. There were 317 fruit flies collected and separated into three species, namely Bactrocera carambolae, B. papayae, dan B. umbrosa, of which B. carambolae had a dominance index of 0.74 and abundance index of 85%. Data on the types of fruit flies can be used as primary data to determine the preparation of pest prevention efforts.

Abstract

SSR marker is one of the genetic markers widely applied in plant breeding programs. The application of molecular markers in plant breeding is meant to accelerate the selection of cross-progeny. The research aimed to identify the SSR primers polymorphism between the parent and control that linked to Al tolerance and verify the cross-progeny of five crosses. The result gained from 37 SSR primers used in this study showed that only nine primers are polymorphic. These nine polymorphic primers are RM257, RM214, RM247, RM205, RM490, RM262, RM569, RM271, and RM19. The application of polymorphic markers on five cross-progeny which have shown the same band pattern as the parents and tolerant control on the use of 9 SSR primers recorded as follows: RM257 2 lines, RM214 5 lines, RM247 5 lines, RM205 lines, RM490 13 lines, RM262 5 lines, RM569 7 lines, RM271 4 lines, and RM19 6 lines. The selected SSR primers linked to Al tolerance in this research can be used as a reference for molecular breeding strategies to develop new Al tolerance rice varieties in dryland conditions.

Abstract

Chili pepper is an important agricultural crop but is highly vulnerable to viral diseases, including Pepper yellow leaf curl Indonesia virus (PepYLCIV). This study investigated the biochemical response of chili plants to PepYLCIV infection by examining changes in antioxidant enzyme activities: peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX). The effects of sample handling methods on enzyme activity measurements were also evaluated. The experiment was conducted in a biosafety greenhouse using a factorial design with four replications. The treatments included two chili varieties (Bara and Bonita), plant condition (healthy and PepYLCIV-infected), sample types (fresh leaf tissue and frozen leaf tissue stored at −80 °C), and seven sampling times (1, 3, 5, 7, 14, 21, and 28 days post-inoculation). Result showed that POD activity was significantly higher in infected plants than in healthy plants, whereas CAT and APX activities showed no significant differences between plant health conditions. Fresh samples consistently exhibited higher enzyme activity than frozen samples. POD and CAT activities peaked at 28 days post-inoculation, while APX activity was the highest at 5 days post-inoculation and fluctuated over time. These findings highlight the importance of considering infection status, sampling time, and sample processing when evaluating antioxidant enzymes in plant–virus interaction studies.
