Persilangan antara dua tetua dengan masing-masing keunggulan dan kemudian dilakukan seleksi akan menghasilkan galur harapan. Penelitian ini bertujuan untuk mengetahui penampilan galur harapan F9 padi beras hitam hasil persilangan “Baas Selem vs Situ Patenggang” yang berdaya hasil tinggi. Percobaan dilaksanakan di lahan sawah di desa Nyur Lembang, kabupaten Lombok Barat pada April–Agustus 2017. Percobaan ditata dalam Rancangan Acak Kelompok (RAK) dengan 10 genotipe padi sebagai perlakuan yang diulang tiga kali yaitu 7 galur harapan F9 padi beras hitam, 2 tetua (Situ Patenggang dan Baas Selem), dan 1 varietas pembanding peka kekeringan (IR20). Penanaman secara sistem gogo pada petak berukuran 3 x 4 m berjarak tanam 25 x 25 cm. Pengairan diberikan bila tanaman pembanding menunjukkan gejala daun menggulung. Hasil penelitian menunjukkan bahwa galur G1(F9 2/1/1) relatif memiliki daya hasil tinggi yaitu 6.53 ton ha-1dengan karakter berat gabah per rumpun (55.68 gram), jumlah gabah berisi per malai (122.45 butir), panjang malai (24.08 cm) dan jumlah anakan produktif per rumpun sebanyak17.53 batang; dan galur G7 (F9 3/4/1) berdaya hasil 6.35 ton ha-1dengan karakter berat gabah per rumpun (50.47 gram), jumlah gabah berisi per malai (124.15 butir), panjang malai (24.02 cm) dan jumlah anakan produktif per rumpun sebanyak 18.30 batang.Kata kunci: gabah, bulk, seleksi, sistim gogo Crossing between two parents with each advantages and then selection will produce a elite line. The aim of this research is to know the appearance of F9 rice line of black rice from "Baas Selem vs Situ Patenggang" crossing which has high yield. The experiment was conducted on rice field in Nyur Lembang village, West Lombok district during April to August 2017. The experiment was arranged in Randomized Block Design of 10 rice genotypes treatment with three replications i.g F9 lines of black rice, 2 parents (Situ Patenggang and Baas Selem), and 1 varieties of drought-sensitive comparison (IR20). Gogo planting system in a plot of 3 x 4 m with spacing 25 x 25 cm. Watering was given when comparative plants (IR20) show symptoms of leaf curl. The results shows that the G1 line (F9 2/1/1) had relatively high yieldof 6.53 ton ha-1 with weight of grain per clump (55.68 gram), grain per panicle (122.45 grains ), panicle length (24.08 cm), and number of productive tillers per clump of 17.53 stalks; and G7 line (F9 3/4/1) yielded 6.35 ton ha-1 with grain weight per clump (50.47 gram), number of grains per panicle (124.15 grains), panicle length (24.02 cm), and number of productive tiller per clump as much as 18,30 stalks.Keywords: grain, bulk, selection, gogo system
ABSTRAKPenelitian ini bertujuan untuk mengetahui daya hasil dari beberapa galurgenerasi F3 r padi beras merah tipe baru hasil persilangan varietas Fatmawati dan IPB3S dengan padi beras merah. Penelitian dilakukan di lahan sawah Desa Nyurlembang, Kecamatan Narmada, Kabupaten Lombok Barat, Provinsi NTB, dengan ketinggian tempat ± 127 mdpl pada bulan Juli sampai dengan Oktober 2017. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 25 perlakuan yaitu 20 galur generasi F3 padi beras merah, tiga tetua (galur harapan padi beras merah G9, Fatmawati, IPB 3S) dan dua varietas pembanding (Impago Unram 1, Aek Sibondang) diulang dua kali. Hasil penelitian menunjukkan bahwa semua karakter yang diamati menunjukkan perbedaan yang nyata (signifikan). Terdapat 13 galur dari 20 galur padi beras merah memiliki potensi hasil tinggi diatas rata-rata hasil kultivar tetua dan pembandingnya yaitu G17, G9, G18, G13, G12, G15, G8, G14, G7, G11, G6, G19 dan G20 yaitu secara berturut-turut 11.30 ton.ha -1 , 9.44 ton.ha -1 , 9.21ton.ha -1 , 9.17ton. ABSTRACTThe aim of this research was to know the potential of several lines of F3 generation of new red rice from the crossbreeding of Fatmawati and IPB3S varieties with red rice. The research was conducted in Nyurlembang Village, Narmada District, West Lombok Regency, West Nusa Tenggara Province, with elevation of ± 127 m above sea level from July to October 2017. The experiment design was Randomized Block Design (RAK) with 25 treatments i.e. 20 red rice lines, three parents and two comparator varieties. The result shows that all observed characters were significant differences. There are 13 lines of 20 red rice lines have high yield potential above the average yield of the parent and comparator varieties are G17,
