Abstract

Increasing production and yield quality of cayenne pepper can be done by assembling superior varieties through plant breeding programs. Information related to genetic diversity and heritability is very important for establishing a variety. This research aims to obtain information about genetic diversity and heritability values in the vegetative characters of the first generation (M1) cayenne pepper mutant genotype. The research was carried out from May to September 2023 at the Wedomartani Experimental Garden, Faculty of Agriculture, UPN "Veteran" Yogyakarta using 70 mutant genotypes (M1) and three comparison varieties, namely Ori 121, Kaliber, and Cempluk for a total of 73 genotypes. The experimental design used was an Augmented Design with a Randomized Complete Block Design (RCBD) as the environmental design. The results of the research show that the characteristics of stem diameter, petiole length and leaf length in cayenne pepper have extensive genetic diversity and have high heritability. These characters can be used as selection criteria because they are more influenced by genetic factors than environmental factors.Keywords: mutation, genetic diversity, heritability INTISARIPeningkatan produksi dan kualitas hasil pada cabai rawit dapat dilakukan dengan perakitan varietas unggul melalui program pemuliaan tanaman. Informasi terkait keragaman genetik dan heritabilitas sangat penting untuk perakitan suatu varietas. Penelitian ini bertujuan untuk mendapatkan informasi tentang keragaman genetik dan nilai heritabilitas pada karakter vegetatif genotipe mutan cabai rawit generasi pertama (M1). Penelitian dilaksanakan pada bulan Mei sampai September 2023 di Kebun Percobaan Wedomartani Fakultas Pertanian UPN “Veteran” Yogyakarta menggunakan 70 genotipe mutan (M1) dan tiga varietas pembanding yaitu Ori 121, Kaliber, dan Cempluk sehingga total terdapat 73 genotipe. Rancangan percobaan yang digunakan yaitu Rancangan Bersekat (Augmented Design) dengan Rancangan Acak Kelompok Lengkap (RAKL) sebagai rancangan lingkungan. Hasil penelitian menunjukkan bahwa karakter diameter batang, panjang tangkai daun, dan panjang daun pada cabai rawit memiliki nilai keragaman genetik yang luas serta memiliki nilai heritabilitas tinggi. Karakter-karakter tersebut dapat dijadikan kriteria seleksi karena lebih banyak dipengaruhi oleh faktor genetik daripada faktor lingkungan. Kata kunci: mutasi, keragaman genetik, heritabilitas
