Abstract

Padi lokal memiliki keunggulan pada rasa dan aroma, namun memiliki produksi yang rendah dan umur panen yang lama sehingga kurang unggul. Upaya untuk memperbaiki genetik padi lokal adalah melalui persilangan buatan. Tujuan penelitian ini adalah untuk mempelajari tingkat keberhasilan persilangan, heterosis, karakter kualitatif dan kuantitatif F1, dan kekerabatan F1 dengan tetuanya. Penelitian dilaksanakan di Kecamatan Tallunglipu, Kabupaten Toraja Utara dari Januari 2019 hingga Juli 2020. Metode persilangan yang digunakan yaitu single cross dan resiprocal cross menggunakan padi lokal aromatik Pare Bau dengan Inpari 4 sehingga diperoleh dua kombinasi persilangan. Hasil penelitian menunjukkan persentase keberhasilan persilangan single cross sebesar 14,4% dan persilangan resiprok sebesar 25,5%. Karakter hasil F1 persilangan resiprok, jumlah gabah bernas per malai (164,2 gabah) dan bobot gabah bernas per rumpun (96,4 g), lebih tinggi dibandingkan F1 single cross. Karakter keharuman pada waktu berbunga terbaik dihasilkan oleh tanaman F1 single cross B1 senilai 92,2% dan B2 senilai 95%. Nilai heterosis dan heterobeltiosis tertinggi adalah F1 resiprok pada semua karakter yang diamati. Generasi F1 hasil single cross (B1 dan B2) memiliki kekerabatan dekat dengan Pare Bau, sedangkan generasi F1 hasil persilangan resiprok (RB1, RB2, RB3, RB4, dan RB5) membentuk kelompok genetik tersendiri tetapi memiliki kekerabatan dekat dengan Inpari 4. ABSTRACTThe rice landrace has a great taste and aroma, but has low yield and late maturity. The artificial crossing is one of ways to improve the genetics performance of the rice landrace. This study purposed to observe the success rate of crosses, heterosis, heterobeltiosis, qualitative and quantitative characters of F1, and genetic relationship of the F1with its parents. This research was conducted in Tallunglipu District, North Toraja Regency from January 2019 to July 2020. The crosses method used were single cross and reciprocal cross using local aromatic Pare Bau and Inpari 4 varieties in order to obtain two cross combinations. The results showed the success rate of the single cross was 14,4% and the reciprocal cross was 25,5%. The characteristics of the F1 reciprocal crosses, the number of fully developed grain per panicle (164,2 grain) and the weight of pithy grain per clump (96,4 g), was higher than the F1 single cross. The best level of aroma character at the time flowering was produced by F1 single cross i.e B1 92,2% and B2 95%. Resiprocal F1 had the highest value of heterosis and heterobeltiosis in all observed characters. Single cross lines (B1 and B2) were closely related to Pare Bau, while reciprocal cross lines (RB1, RB2, RB3, RB4, and RB5) formed separate genetic groups. However, reciprocal cross lines were closely related to Inpari 4.

Abstract

Penelitian ini bertujuan untuk mengetahui dan mengkaji pengaruh auksin dan pupuk organik cair terhadap pertumbuhan dan produksi bawang merah dari biji botani. Penelitian ini dilaksanakan di Teaching Farm, Fakultas Pertanian, Universitas Hasanuddin, Makassar. Lokasi penelitian terletak dengan koordinat 5° 7’40.07”s 119°28’48.94”E di ketinggian 9 m dpl. Penelitian dilaksanakan mulai Agustus-Desember 2020. Penelitian ini menggunakan rancangan faktorial 2 faktor dalam rancangan acak kelompok, dimana sebagai faktor pertama yaitu auksin yang terdiri dari 4 taraf yaitu 0 ppm; 100 ppm; 200 ppm; 300 ppm dan sebagai faktor kedua yaitu pupuk organik cair yang terdiri dari 4 taraf yaitu 0 ppm; 1500 ppm; 3000 ppm; 4500 ppm. Hasil penelitian menunjukkan bahwa perlakuan perendaman bibit pada larutan auksin dengan konsentrasi 300 ppm selama 6 menit dan penyemprotan pupuk organik cair dengan konsentrasi 4500 ppm menghasilkan bobot umbi segar pertanaman terberat (28,56 g), bobot umbi kering pertanaman terberat (26,17 g), diameter umbi segar terlebar (37,70 mm), diameter umbi kering terlebar (36,31 mm) dan produksi umbi perhektar terberat (20,93 t). Karakter yang berkorelasi sangat nyata positif dengan produksi umbi perhektar adalah tinggi tanaman, jumlah daun, bobot umbi segar pertanaman, bobot umbi kering pertanaman, diameter umbi segar dan diameter umbi kering dengan nilai koefisien korelasinya secara berturut-turut adalah 0,92**, 0,89**, 0,98**, 0,99**, 0,99** dan 0,99**.

Abstract

Shafira taro (Colocasia esculenta var. antiquorum) is a type of small-tubered taro, also known as Japanese taro, which is traded internationally. This study aims to examine the effect of various concentrations of Thidiazuron (TDZ) and Benzyl Amino Purine (BAP), as well as the combination of Thidiazuron with Naphtalene Acetic Acid (NAA) and BAP with NAA, on the multiplication of Shafira taro shoots through in vitro culture techniques. The method used in this study uses in vitro culture techniques, which are modern plant propagation science known in the world of biotechnology and allow controlled propagation and improvement of plant species. An essential component of this technique is using plant growth regulators (PGRs), critical for modulating various physiological processes in plant cells and tissues. PGRs promote growth and differentiation, optimize secondary metabolite production, and increase plant resistance. This study used a combination of main PGR treatments (TDZ, BAP, and NAA) with a total of 13 (thirteen) treatment combinations using a randomized block design, namely: k0: Control, t1: TDZ 1 ppm, t2: TDZ 2 ppm, t3: TDZ 3 ppm, b1: BAP 1 ppm, b2: BAP 2 ppm, b3: BAP 3 ppm, t1n1: TDZ 1 ppm + NAA 0.5 ppm, t2n1: TDZ 2 ppm + NAA 0.5 ppm, t3n1: TDZ 3 ppm + NAA 0.5 ppm, b1n1: BAP 1 ppm + NAA 0.5 ppm, b2n1: BAP 2 ppm + NAA 0.5 ppm, b3n1: BAP 3 ppm + NAA 0.5 ppm. Each treatment was repeated thrice, with three tissue culture bottles per repetition, resulting in 117 tubes containing one explant. The results showed that the highest number of roots, leaves, and shoots was achieved with 1 ppm BAP, while the optimal fresh weight and shoot height were obtained with 2 ppm BAP. Treatments involving combinations of TDZ, TDZ + NAA, and BAP + NAA did not produce significant results for shoot multiplication.
