EVALUASI KETAHANAN BEBERAPA VARIETAS CABAI TERHADAP VIRUS GEMINI

Abstract

Chili is a horticultural commodity that has high economic value, but the presence of the Gemini virus and the low level of plant resistance are thought to be one of the causes of low crop productivity. The aims of the study were to evaluate the differences in the resistance response of chili varieties to the Gemini virus. The study was conducted using a randomized block design with three treatments and each treatment was repeated six times. The treatments were Sreet variety/cayenne pepper (V1), Lado F1 Variety/curly chili (V2) and Pillar Variety F1/big chili (V3). The variables observed were incubation period, plant height, incidence and severity of disease along with the number of branches on chili plants. Observational data obtained were analyzed using variance, and it was continued with the Least Significant Difference (BNT) test at a 95% confidence level. The results showed that the longest incubation period was V1, with an incubation period of 10 day followed by V2 and V3 with an incubation period of 7 day each. The lowest rate and incidence of Gemini virus disease was found in the V3, which was 14.66% and 66.67% respectively. The lowest rate and severity of Gemini virus disease was found in the V1 with the lowest percentage level of 66.67% and 29.33% respectively. The V1 gave a response of plant height of 14.5 cm at 35 day, the highest number of branches in the V2 was 6.8 branches at 55 day.
