Peningkatan kualitas buah cabai hias dapat dilakukan dengan hibridisasi. Namun teknik hibirdisasi memerlukan waktunyangncukupnlamanuntuknmelihatnindividu baru unggul. Alternatif yang bisa dilakukan dengan memanfaatkan adanya efek metaxenia yang dijumpai pada buah. Penelitiannini dilaksanakanndari bulan Juli 2022 hingga November 2022 di Balai Pengkajian TeknologinPertanian (BPTP) Aceh. Rancangannyangndigunakan adalah RancangannAcaknKelompoknNon Faktorial dengan 4 genotipe cabai hias yaitu Ayesha, Nazla, Violetta dan Syakira dengan persilangan dilakukan secara resiprokal (full dialel). Hasil penelitian menunjukkan persentase keberhasilan paling tinggi didapatkan pada persilangan tangkar dalam Syakira dan persentase keberhasilan bentuk buah paling tinggi didapatkan pada persilangan tangkar dalam Ayesha. Efek metaxenia muncul pada karakter umur panen, bentuk buah, berat buah dan jumlah biji. Kombinasi persilangan Ayesha x Syakira merupakan keberhasilan persilangan tertinggi dalam karakter peubah bentuk buah. Kombinasi persilangan Violetta x Syakira merupakan keberhasilan persilangan tertinggi dalam peningkatan jumlah biji. Kombinasi persilangan Syakira x Violetta merupakan keberhasilan persilangan tertinggi dalam peningkatan berat buah.

Improving the quality of ornamental chilies can be done by hybridization. However, hybridization techniques require quite a long time to see new individuals excel. This research was conducted from July 2022 to November 2022 at the Aceh Agricultural Technology Assessment Center (BPTP). The design used was a Non-Factorial Randomized Group Design with 4 ornamental chili genotypes namely Ayesha, Nazla, Violetta and Syakira with crosses were made reciprocally (full diallel). The results of the study found that the highest percentage of success was found in the closed crosses in Syakira and the highest percentage of success in the fruit form was found in the closed crosses in Ayesha. The effects of metaxenia appear on the characters of harvesting age, fruit shape, fruit weight and number of seeds. The cross combination of Ayesha x Syakira is the highest crossbreeding success in fruit shape variable characters. The combination of the Violetta x Syakira cross was the highest success in increasing the number of seeds. The combination of the Syakira x Violetta cross was the highest success in increasing fruit weight. Keywords: Ornamental chili, hybridized, metaxenia
