Abstract

KERAGAAN KARAKTER KUANTITATIF DAN PARAMETER
GENETIK BEBERAPA GENOTIPE CABAI MERAH KERITING
(Capsicum annum L.) GENERASI M2

ABSTRAK
Usaha peningkatan produksi cabai merah keriting (Capsicum annum L.) dapat
dilakukan melalui pemuliaan mutasi. Penelitian bertujuan untuk mengetahui
keragaan karakter kuantitatif, nilai keragaman genetik dan nilai heritabilitas serta
memperoleh genotipe tanaman sebagai materi genetik generasi M3. Metode
penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) satu faktor
dengan empat ulangan. Perlakuan meliputi lima genotipe cabai merah keriting
generasi M2 dan kontrol varietas Thunder. Penelitian dilakukan pada bulan
Februari sampai Juli 2025 di Kebun Percobaan Fakultas Pertanian UPN “Veteran”
Yogyakarta. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan uji
lanjut dengan Least Significant Difference (LSD) taraf 5%. Hasil penelitian
menunjukkan beberapa genotipe M2 berpengaruh nyata terhadap keragaan karakter
kuantitatif pada tinggi tanaman 45 HST dan 60 HST, diameter batang 45 HST dan
60 HST, umur berbunga, umur panen, jumlah buah per tanaman panen ke-4, serta
bobot buah per tanaman panen ke-4 dan total. Koefisien keragaman genetik tinggi
pada parameter jumlah buah per tanaman panen ke-1, serta bobot buah per tanaman
panen ke-1 sampai 4 dan total. Koefisien keragaman fenotipe tinggi pada parameter
jumlah buah per tanaman panen ke-1 sampai 4 dan total, bobot buah per tanaman
panen ke-1 sampai 4 dan total, dan intensitas serangan virus gemini. Nilai
heritabilitas tinggi pada parameter diameter batang 45 HST, umur berbunga, dan
bobot buah per tanaman panen ke-4. Genotipe TH2-458-31, TH2-458-105, TH2
458-106, dan TH2-458-146 berpotensi diuji lanjut pada generasi M3.

PERFORMANCE OF QUANTITATIVE CHARACTERS AND
GENETIC PARAMETERS OF SOME GENOTYPES OF CURLY RED
CHILI (Capsicum annum L.) GENERATION M2

ABSTRACT
Efforts to increase the production of curly red chili (Capsicum annum L.) can be
carried out through mutation breeding. This study aimed to evaluate the
performance of quantitative traits, estimate genetic variability and heritability
values, and identify potential genotypes as genetic material for the M3 generation.
The research was conducted using a Randomized Complete Block Design (RCBD)
with a single factor and four replications. Treatments consisted of five M2
generation curly red chili genotypes and a control variety (Thunder). The study was
carried out from February to July 2025 at the Experimental Field of the Faculty of
Agriculture, UPN "Veteran" Yogyakarta. Data were analyzed using Analysis of
Variance (ANOVA) and further tested with the Least Significant Difference (LSD)
at a 5% significance level. The results showed that several M2 genotypes had a
significant effect on quantitative traits, including plant height at 45 and 60 DAP,
stem diameter at 45 and 60 DAP, days to flowering, days to harvest, number of
fruits per plant at the fourth harvest, as well as fruit weight per plant at the fourth
harvest and total fruit weight. A high genetic coefficient of variation was observed
in the number of fruits per plant at the first harvest and fruit weight per plant from
the first to the fourth harvest and total. A high phenotypic coefficient of variation
was found in the number of fruits per plant from the first to the fourth harvest and
total, fruit weight per plant from the first to the fourth harvest and total, and the
intensity of gemini virus infection. High heritability values were obtained for stem
diameter at 45 DAP, days to flowering, and fruit weight per plant at the fourth
harvest. Genotypes TH2-458-31, TH2-458-105, TH2-458-106, and TH2-458-146
showed potential for further evaluation in the M3 generation.
