UJI KETAHANAN VARIETAS CABAI (Capsicum spp.) TERHADAP CUCUMBER MOSAIC VIRUS (CMV)
Abstract
ABSTRACT
The aim of this research is to know varieties of chilli that have resistance response to
Cucumber Mosaic Virus (CMV) infection. This study was conducted based on a complete
randomized design (RAL) consisting of four treatments. Each treatment is repeated 4 times so
that there are 16 units of treatment and each unit there are 3 plants so as a whole there are 48
plants. The treated treatments were T0 (without CMV inoculation in pepper/control plants), T1
(CMV inoculation on large pepper/spear varieties), T2 (CMV inoculation of
peppercorn/cameti 1), and T3 (CMV inoculation at cayenne pepper/Green Cakra varieties).
Parameters observed in this study were incubation period (MSI), description of symptoms,
growth and production of plants.
The results of this study are the three varieties of Tombak are categorized as
susceptible varieties of CMV virus infection however the varieties of Tombak have better
resistance than the tested varieties, including varieties that are highly susceptible to CMV
virus infection, however the Spear variety has better resistance of the varieties of Cameti 1 and
Cakra Hijau. Symptoms that arise in the plant tested in the form of mosaic and leaf shape
changes
ABSTRAK
Penelitian ini bertujuan mengetahui varietas cabai yang memiliki respon ketahanan
terhadap infeksi Cucumber Mosaic Virus (CMV). Penelitian ini dilaksanakan berdasarkan
rancangan acak lengkap (RAL) yang terdiri dari empat perlakuan. Setiap perlakuan diulang
sebanyak 4 kali sehingga terdapat 16 unit perlakuan dan setiap unit terdapat 3 tanaman
sehingga secara keseluruhan terdapat 48 tanaman. Perlakuan yang di cobakan adalah T0 (tanpa
inokulasi CMV pada tanaman cabai/kontrol), T1 (inokulasi CMV pada tanaman cabai
besar/varietas Tombak), T2 (inokulasi CMV pada tanaman cabai kriting/varietas cameti 1), dan
T3 (inokulasi CMV pada tanaman cabai rawit/ varietas Cakra Hijau). Parameter yang diamati
dalam penelitian ini adalah masa inkubasi (MSI), deskripsi gejala, pertumbuhan dan produksi
tanaman.
Hasil penelitian ini adalah ketiga varietas Tombak dikategorikan sebagai varietas yang
rentan terhadap infeksi virus CMV namun demikian varietas Tombak memiliki ketahanan yang
lebih baik dari varietas yang diujikan yaitu termasuk varietas yang sangat rentan terhadap
infeksi virus CMV, namun demikian varietas Tombak memiliki ketahanan yang lebih baik dari
varietas Cameti 1 dan Cakra Hijau. Gejala yang timbul pada tanaman yang diuji berupa mosaic
dan adanya perubahan bentuk daun.
