| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk: 1) mengetahui pola segregasi tanaman padi populasi F2 keturunan hasil persilangan Inpago Unsoed 1 dan Delta 9, 2) mengetahui karakter yang paling berhubungan erat dengan hasil tanaman padi, dan 3) mengetahui karakter yang mempunyai nilai pengaruh langsung tinggi terhadap hasil tanaman padi. Penelitian eksperimen ini dilaksanakan di Screen House Fakultas Pertanian, Universitas Jenderal Soedirman pada bulan Oktober 2018 - Februari 2019. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan Augmented design. Faktor yang digunakan yaitu genotip F2 hasil persilangan Inpago Unsoed 1 dan Delta 9. Karakter yang diamati yaitu tinggi tanaman, umur berbunga, jumlah anakan produktif, umur panen, panjang malai, jumlah gabah per malai, bobot gabah per malai, bobot gabah per rumpun, bobot 100 biji, kandungan klorofil, kerapatan stomata, indeks luas daun dan warna daun. Hasil penelitian menunjukkan bahwa pola segregasi tinggi tanaman, umur berbunga, jumlah anakan produktif, panjang malai, jumlah gabah per malai, bobot gabah per malai, bobot gabah per rumpun, bobot 100 biji, kandungan klorofil, kerapatan stomata, dan indeks luas daun berdistribusi normal yang berarti karakter tersebut dikendalikan oleh banyak gen yang diduga merupakan karakter kuantitatif. Umur panen mengikuti nisbah hukum Mendel 9 : 7 yang berarti karakter tersebut dikendalikan oleh gen-gen epistasis resesif duplikat yang diduga merupakan karakter kualitatif. Warna daun mengikuti nisbah hukum Mendel 15 : 1 yang berarti karakter tersebut dikendalikan oleh gen-gen epistasis dominan duplikat yang diduga merupakan karakter kualitatif. Karakter yang paling berhubungan erat dengan hasil tanaman padi yaitu jumlah anakan produktif, bobot gabah per malai dan jumlah gabah per malai. Karakter yang mempunyai nilai pengaruh langsung tinggi terhadap hasil tanaman padi yaitu jumlah anakan produktif, bobot gabah per malai dan bobot 100 biji. Jadi, karakter yang dapat dipertimbangkan sebagai indikator seleksi daya hasil tinggi tanaman padi populasi F2 hasil persilangan Inpago Unsoed 1 dan Delta 9 yaitu jumlah anakan produktif, bobot gabah per malai, bobot 100 biji, dan jumlah gabah per malai. |

| Abtrak (Bhs. Inggris) | This study aims to: 1) determine the rice segregation pattern of population F2 descendants from Inpago Unsoed 1 and Delta 9, 2) knowing the character that is most closely related to rice yields, and 3) knowing the character that has a high direct effect on the yield of rice plants. This experimental research was conducted at Screen House Faculty of Agriculture, Jenderal Sudirman University in October 2018 - February 2019. The design used is Randomized Block Design (RBD) with Augmented design. The factors used were F2 genotype from Inpago Unsoed 1 and Delta 9 crosses. The characters observed were plant height, flowering age, number of productive tillers, harvest age, panicle length, number of grain per panicle, grain weight per panicle, grain weight per clump, weight of 100 seeds, chlorophyll content, stomata density, leaf area index and color leaf. The results showed that the segregation pattern of plant height, flowering age, number of productive tillers, panicle length, number of grain per panicle, grain weight per panicle, grain weight per clump, weight of 100 seeds, chlorophyll content, stomata density, and leaf area index were normally distributed which means that the character is controlled by many genes that are thought to be quantitative characters. Harvest age follows Mendel 9: 7 legal ratio, which means that the character is controlled by duplicate recessive epistasis genes that are thought to be qualitative characters. Leaf color follows the Mendel 15: 1 legal ratio, which means that the character is controlled by duplicate dominant epistasis genes which are thought to be qualitative characters. The characters that are most closely related to the yield of rice are the number of productive tillers, grain weight per panicle and number of grains per panicle. Characters that have a high direct effect on rice yields are the number of productive tillers, grain weight per panicle and weight of 100 seeds. Thus, the character that can be considered as an indicator of the yield of rice plant population F2 from the results of Inpago Unsoed 1 and Delta 9 crosses is the number of productive tillers, grain weight per panicle, weight of 100 seeds, and number of grain per panicle. |
