INGKASAN RAKA FAUZI MITREKA. 195040200111199. Uji Daya Hasil Jagung Pakan (Zea mays L.) Dari Hasil Top Cross. Dibawah bimbingan Prof. Ir. Arifin Noor Sugiharto, MSc., Ph.D. Jagung pakan (Zea mays L.) berperan penting sebagai bahan makanan ternak dan bahan baku industri. Selain padi, kebutuhan akan jagung sebagai alternatif kebutuhan karbohidrat semakin meningkat seiring dengan peningkatan jumlah penduduk. Peningkatan permintaan pasar salah satunya disebabkan oleh perkembangan industri peternakan yang pada proses produksinya memerlukan jagung sebagai campuran pakan ternak. Penggunaan varietas hibrida merupakan salah satu solusi dalam meningkatkan produksi jagung dalam negeri terutama pada jagung pakan. Penelitian ini dilaksanakan pada bulan September-Desember 2022 di Kebun Percobaan Agrotechnopark (ATP) Universitas Brawijaya yang terletak di Desa Jatikerto, Kecamatan Kromengan, Kabupaten Malang, Jawa Timur. Alat yang digunakan dalam penelitian adalah cangkul, sabit, gunting, timbangan analitik, penggaris, meteran, kamera digital, spidol permanen, kain warna abuabu, kertas label (mecollin), alfaboard dan sprayer. Bahan yang digunakan yaitu 27 genotipe jagung pakan generasi S2 hasil top cross dan 1 genotipe jagung pakan hibrida sebagai varietas pembanding. Penelitian dilakukan dengan menggunakan Rancangan Acak Kelompok dengan 3 kali ulangan. Jarak tanam yang digunakan adalah 60 cm x 30 cm x 90 cm. Variabel yang diamati meliputi diameter batang, warna silk, warna anther, warna glume, umur anthesis, umur silking, tinggi tanaman, tinggi letak tongkol, jumlah tongkol, bobot tongkol perplot, bobot biomassa, bobot tongkol dengan kelobot, bobot tongkol tanpa kelobot, jumlah baris, panjang tongkol, panjang tangkai, diameter tongkol, bobot janggel, bobot 100 biji, bobot biji, rendemen biji, potensi hasil. Data yang telah didapat kemudian di uji menggunakan analisis ragam dengan Uji F (ANOVA) taraf 5%. Apabila hasil yang didapatkan berbeda nyata maka dilanjutkan dengan menggunakan Uji BNJ taraf 5%. Hasil dari penelitian yang telah dilakukan pada setiap karakter, didapatkan bahwa setiap galur yang diuji pada pengamatan warna silk, anther, dan glume memiliki karakter dengan tingkat skor presentase keseragaman yang berbedabeda. Sedangkan jumlah skor potensi dari 27 galur yang diuji pada karakter kuantitatif, terdapat 8 galur yang memiliki potensi nilai penampilan tinggi diatas rata-rata seluruh galur dan dibandingkan dengan varietas pembanding Syngenta Perkasa (NK6172). Galur tersebut yaitu UB1, UB9, UB12, UB13, UB14, UB15, UB17, dan UB23 yang memiliki potensi untuk dikembangkan. Sementara itu didapatkan bahwa nilai KKG, KKF, dan Heritabilitas pada 19 karakter yang diamati termasuk dalam kategori rendah hingga tinggi.

SUMMARY Raka Fauzi Mitreka. 195040200111199. Yield Test of Yellow Corn (Zea mays L.) From the Results of Top Cross. Supervised by Prof. Ir. Arifin Noor Sugiharto, MSc., Ph.D. Yellow corn (Zea mays L.) is important as animal feed and industrial raw material. In addition to rice, the need for corn as an alternative to carbohydrate needs is increasing along with the increase in population. One of the reasons for the increase in market demand is the development of the livestock industry, which in its production process requires corn as a mixture of animal feed. The use of hybrid varieties is one of the solutions to increase domestic corn production, especially for fodder maize. This research was conducted in September-December 2022 at the Experimental Garden of Agrotechnopark (ATP) Brawijaya University which is located in Jatikerto Village, Kromengan District, Malang Regency, East Java. The tools used in this research are hoe, sickle, scissors, analytical scale, ruler, meter, digital camera, permanent marker, gray cloth, label paper (mecollin), alphaboard, and sprayer. The materials used were 27 genotypes of maize for S2 generation from top cross and 1 genotype of maize for hybrid feed as a comparison variety. The study was conducted using a Randomized Block Design with 3 replications. The spacing used is 60 cm x 30 cm x 90 cm. Variables observed included stem diameter, silk color, anther color, glume color, age of anthesis, age of silking, plant height, cob height, number of cobs, weight of cob per plot, weight of biomass, cob weight with cornhusk, cob weight without cornhusk, number of rows of seeds, length of the cob, length of the stalks, diameter of the cob, cob weight, the weight of 100 seeds, weight of seed, seed yield, potential yield per hectare. The data obtained is then tested using analysis of variance with the F test (ANOVA) at a 5% level. If the results obtained are significantly different, then it is continued by using the 5% BNJ test. The results of research that has been conducted on each character, it was found that each line tested on silk, anther, and glume color observations had characters with different levels of uniformity percentage scores. While the total potential scores of the 27 lines tested on quantitative characters, there are 8 lines that have the potential for high performance values above the average of all lines and compared to the comparison variety Syngenta Perkasa (NK6172). The lines are UB1, UB9, UB12, UB13, UB14, UB15, UB17, and UB23 have the potential to be developed. Meanwhile it was found that the KKG, KKF, and Heritability values for the 19 observed characters were in the low to high category.
