Abstract The use of cytoplasmic-genic male sterility (CGMS) systems greatly increases the efficiency of hybrid seed production. Although marker development and candidate gene isolation have been performed for the Restorer-of-fertility (Rf) gene in pepper (Capsicum annuum L.), the broad use of CGMS systems has been hampered by the instability of fertility restoration among pepper accessions, especially sweet peppers, due to the widespread presence of the Unstable Restorer-of-fertility (Rfu) locus. Therefore, to investigate the genetic factors controlling unstable fertility restoration in sweet peppers, we developed a segregation population from a cross between a male-sterile line and an Rfu-containing line to examine the inheritance of Rfu. Individuals with unstable restoration vs. sterility segregated at a 3:1 ratio, indicating that a single dominant gene controls unstable fertility restoration. Genetic mapping delimited the Rfu locus to a 479 kb genomic region on chromosome 6 flanked by two markers, which is close to but different from the previously identified Rf-containing region. The Rfu-containing region harbors a pentatricopeptide repeat (PPR) gene, along with 13 other candidate genes. In addition, this region is syntenic to the genomic region containing the largest number of Rf-like PPR genes in tomato. Therefore, the dynamic evolution of PPR genes might be responsible for both the restoration and instability of fertility in pepper. During genetic mapping, we developed various molecular markers, including one that co-segregated with Rfu. These markers showed higher accuracy for genotyping than previously developed markers, pointing to their possible use in marker-assisted breeding of sweet peppers.

<em>Konsumsi cabai rawit terus meningkat namun produktivitasnya masih rendah, sehingga diperlukan pemuliaan yang mengarah pada perbaikan daya hasil. Penelitian ini bertujuan untuk menganalisis keragaman genetik, korelasi antar karakter, heritabilitas arti luas, dan nilai kemajuan seleksi populasi F3 cabai rawit. Penelitian ini dilaksanakan di Kebun Percobaan Leuwikopo, IPB, Dramaga, Bogor dan Laboratorium Genetika dan Pemuliaan Tanaman, Departemen Agronomi dan Hortikultura, IPB. Percobaan menggunakan 5 genotipe tetua dan 6 genotipe F3 cabai rawit, dengan genotipe tetua yang diulang sebanyak 3 ulangan dan genotipe F3 tanpa ulangan. Hasil penelitian menunjukkan bahwa karakter bobot buah per tanaman dan jumlah buah per tanaman memiliki keragaman genetik luas pada semua genotipe. Semua karakter pengamatan berkorelasi positif terhadap daya hasil kecuali umur berbunga dan umur panen. Nilai heritabilitas arti luas dengan kriteria tinggi terdapat pada karakter bobot buah per tanaman, bobot per buah, dan panjang buah. Hasil seleksi indeks yang dilakukan menunjukkan kemajuan seleksi yang besar pada karakter bobot buah per tanaman dan jumlah buah per tanaman.</em>
