Beras Basmati merupakan beras berindikasi geografis dengan karakteristik beras panjang dan ramping. Pembangunan evolusi pangan dapat dilakukan melalui persilangan tanaman guna menghasilkan kultivar Basmati yang dapat tumbuh dan cocok serta berdaya hasil tinggi bila ditanam di Indonesia. Penelitian ini bertujuan untuk 1) mengetahui variabilitas genetik dan fenotipe, 2) mengetahui nilai duga heritabilitas, 3) mengetahui nilai kemajuan genetik, dan 4) mendapatkan komponen pertumbuhan atau hasil yang memiliki efektivitas seleksi tinggi. Percobaan dilakukan di sawah di Desa Karangambas, Kecamatan Padamara, Kabupaten Purbalingga pada November 2023 hingga Maret 2024 menggunakan Perancangan Acak Blok (RAK). Faktor tunggal pada penelitian ini  berupa 12 genotipe. Hasil penelitian menunjukkan bahwa variabilitas genetik kriteria luas terdapat pada tinggi tanaman, jumlah anakan, umur berbunga, umur panen, panjang malai, jumlah gabah per malai, persentase gabah isi per malai, bobot gabah per rumpun, panjang beras, dan lebar beras. Variabilitas fenotip kriteria luas pada semua karakter. Nilai heritabilitas arti luas kriteria tinggi pada tinggi tanaman, jumlah anakan, umur berbunga, umur panen, panjang malai, jumlah gabah per malai, persentase gabah isi per malai, bobot gabah isi per rumpun, panjang beras dan lebar beras. Nilai kemajuan genetik  kriteria tinggi terdapat pada tinggi tanaman, jumlah anakan, jumlah gabah per malai, persentase gabah isi per malai, bobot gabah per rumpun, dan panjang beras. Efektivitas seleksi akan efektif pada jumlah anakan, jumlah gabah per malai, persentase gabah isi per malai, dan bobot gabah per rumpun

Basmati rice is a rice with geographic indications with a long and slender rice character. The development of food evolution can be carried out through plant crossing to produce Basmati cultivars that can grow and are suitable and have high yields when planted in Indonesia This study aims to 1) determine the genetic and phenotypic variability, 2) determine the value of expected herritability, 3) determine the value of genetic progress, and 4) obtain growth components or yield that have high selection effectiveness. The experiment was conducted at a rice fields in Karangambas Village, Padamara District, Purbalingga Regency on from November 2023 to March 2024 using a Randomized Block Design (RBD). The single factor in this study was complete 12 rice genotypes. The results of the study showed that genetic variability broad criteria was obtained in most of the characters, meanwhile in the narrow criteria was obtained in number of productive tillers. The phenotypic variability of narrow criteria was obtained in all characters. The heritability value of the broad criteria was obtained in most of the characters, meanwhile in the medium criteria was obtained in number of productive tillers. The genetic advances high criteria was obtained in 6 characters, medium criteria in 3 characters, and low criteria in 2 characters. Selection will be effective on the plant height, number of tillers, number of grains per panicle, percentage of filled grain per panicle, weight of grain per clump
