Abstract

Salah satu upaya peningkatan produktivitas padi sawah irigasi adalah dengan merakit Varietas Unggul Baru (VUB) yang memiliki daya hasil tinggi serta sesuai dengan kondisi agroekosistem, sehingga perlu adanya peningkatan stabilitas suatu galur agar tetap berproduksi tinggi. Tujuan penelitian ini untuk mengevaluasi keragaan agronomi hasil 31 galur padi (Oryza sativa L.) inbrida sawah irigasi dengan potensi hasil tinggi pada dataran rendah Sukamandi. Penelitian dilaksanakan pada bulan September 2021 – Januari 2022 (Musim Tanam (MT) 2-2021) di Kebun Percobaan Balai Besar Penelitian Tanaman Padi Sukamandi. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 39 perlakuan yang terdiri dari 31 galur dan 8 varietas pembanding yaitu Inpari 30, Inpari 32, Inpari 42, Cakrabuana, Inpari Digdaya, Inpari Gemah, Inpari 47, dan Inpari 48 yang diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa terdapat galur-galur yang diuji memiliki perbedaan yang nyata pada seluruh karakter keragaan agronomi. Sebanyak delapan galur harapan nyata mempunyai hasil panen mendekati varietas pambanding terbaik Inpari 42 (5,5 t/ha) dengan kisaran 4,25-5,34 t/ha. Galur-galur tersebut yaitu BP 4126f-Kn-1-WBC-2-3-4, BP 30546D-SKI-19-3-2, B14667E-MR-18-5-Kn-1, B14928D-MR-27-2-5-3-PN-2, IR 102860-8:42-B-B, B1398E-KA-6-3, PR40786-16-2-0-SBY-0-CRB-0, dan BP18322-3-2-JK-0-IDN-2-SKI-6-PWK-2.

Abstract

Differences and similarities in morphological characters in rice plants can be distinguished through characterization activities. Morphological characterization needs to be carried out to identify the superior characters that appear, especially characters related to the growth and development of rice plants which can increase the yield potential of rice. The results of the morphological characterization can be used to determine the close kinship and genetic distance between plants. This study aims to determine the kinship relationship and genetic distance formed in several selected superior varieties of rice plants. The research was conducted at the Experimental Garden of the Sukamandi Rice Research Center. The research method used is descriptive experimental method with a treatment of 44 varieties of rice, repeated 3 times. Observational data were analyzed using Ntsys 2.02 and 2.11 software with the UPGMA method. The results showed that several selected high yielding varieties had similarities in several morphological characters such as leaf width, leaf angle, leaf neck color, leaf midrib color, leaf tongue color and leaf tongue shape. The resulting similarity coefficient is 0.75 and seven groups with close kinship are formed. The genetic distance formed in several selected superior varieties of rice plants has a narrow diversity with a value of 0.25. The results for both parameters indicate that the resulting genetic diversity is small. This cannot be used as a cross parent but can be used as genetic material which is re-analyzed to increase its diversity.
