Plant breeding is the right step to increase rice productivity. This study aims to examine genetic diversity, heritability, expected genetic progress and correlations between traits of local upland rice cultivars to improve the superior characteristics of upland rice cultivars. This study used a randomized block design (RAK) with six cultivars, namely K1 = Untad 1, K2 = Untad 2, K3 = Untad 3, K4 = Untad 4, K5 = Untad 5, and K6 = Untad 6 which was repeated four times in order to obtain 24 trial plots. The results showed that the panicle length, the number of grain/panicles, and the percentage of empty grain were classified as medium KKG. Characteristics of plant height, number of leaves, leaf blade length, number of tillers, number of productive tillers, age of panicle exit, age of harvest, weight of 1000 grain, yield of tonnes ha-1 were classified as low KKG. Characteristics of plant height, leaf blade length, panicle exit age, harvest age and the number of grain/panicles are high heritability values ??and high expectations of genetic progress. The traits that were positively correlated to the yield were the age at which the panicle emerged and the number of grain/panicles.

Pemuliaan tanaman merupakan langkah tepat untuk meningkatkan produktivitas padi. Penelitian ini bertujuan untuk mengkaji keragaman genetik, heritabilitas, kemajuan genetik harapan dan korelasi beberapa antar sifat kultivar padi gogo lokal untuk meningkatkan sifat kultivar padi gogo yang unggul. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan enam kultivar yaitu K1 = Untad 1, K2= Untad 2, K3= Untad 3, K4= Untad 4, K5= Untad 5, dan K6= Untad 6 yang diulang sebanyak empat kali sehingga diperoleh 24 petak percobaan. Hasil penelitian menunjukkan sifat panjang malai, jumlah gabah/malai, persentase gabah hampa tergolong KKG sedang. Sifat tinggi tanaman, jumlah daun, panjang helaian daun, jumlah anakan, jumlah anakan produktif, umur keluar malai, umur panen, berat 1000 gabah, hasil ton ha-1 tergolong KKG rendah. Sifat tinggi tanaman, panjang helaian daun, umur keluar malai, umur panen dan jumlah gabah/malai merupakan nilai heritabilitas tinggi dan kemajuan genetik harapan tinggi. Sifat yang berkorelasi positif terhadap hasil yaitu sifat umur keluar malai dan jumlah gabah/malai. Kata Kunci: Potensi genetik, padi gogo dan seleksi massa |
