Abstract

Galur turunan esensial merupakan kelompok tanaman hasil pemuliaan padi yang memiliki sifat unggul dan berpotensi dikembangkan sebagai varietas baru. Penelitian ini bertujuan untuk mengevaluasi keragaan serta hubungan antar komponen hasil terhadap produktivitas galur turunan esensial yang dibandingkan dengan varietas tetua Inpari IR Nutri Zinc. Pengujian dilaksanakan pada akhir Januari hingga Juni 2025 di IP2SIP Muara, Bogor, menggunakan rancangan kelompok lengkap terpadu dengan empat ulangan. Galur BP35650*4-SKI-1-3-KNG-0-SKI-0 memiliki umur paling genjah dibandingkan tetua Inpari IR Nutri Zinc. BP35650*4-SKI-38-2-KNG-0-SKI-0 postur tanaman nyata lebih tinggi dibandingkan Inpari IR Nutri Zinc. Semua galur menunjukan tidak berbeda nyata dengan pada karakter Gabah kering Giling (GKG) dengan tetua backcross Inpari IR Nutri Zinc. Beberapa galur mengalami perbaikan karakter ukuran gabah dari tetua backcross (Inpari IR Nutri Zinc = 22,85 g), diantaranya: BP35650*4-SKI-1-3-KNG-0-SKI-0 (25,38 g), BP35650*4-SKI-16-1-KNG-0-SKI-0 (24,83 g), BP35650*4-SKI-19-2-KNG-0-SKI-0 (25,60 g), dan BP35650*4-SKI-22-3-KNG-0-SKI-0 (24,83 g). Jumlah gabah isi permalai menunjukan korelasi kuat terhadap hasil panen pada pengujian ini. Sebaliknya, panjang malai dan bobot 1000 butir memiliki hubungan yang lemah atau bahkan negatif terhadap hasil. Temuan ini memberikan dasar dalam pemilihan galur potensial yang memiliki produktivitas tinggi dan mendukung upaya pengembangan varietas padi unggul. ABSTRACT Essential derived rice lines are a group of breeding lines that have superior properties and have the potential to be developed as new varieties. This study aims to evaluate the diversity and relationship between yield components to the productivity of essential derivative strains compared to the parent variety Inpari IR Nutri Zinc. The test was carried out from the end of January to June 2025 at IP2SIP Muara, Bogor, using a randomized complete block design (RCBD) with four replicates. The BP35650*4-SKI-1-3-KNG-0-SKI-0 strain (106 hst) has the longest lifespan compared to the Inpari IR Nutri Zinc elder (109 hss). BP35650*4-SKI-38-2-KNG-0-SKI-0 (107.1 cm) real plant posture is higher than Inpari IR Nutri Zinc (99.3 cm). All strains show no real difference from the character of GKG with the elder backcross Inpari IR Nutri Zinc. Several lines showed larger grain size compared to Inpari IR Nutri Zinc (22,85 g), including: BP35650*4-SKI-1-3-KNG-0-SKI-0 (25.38 g), BP35650*4-SKI-16-1-KNG-0-SKI-0 (24.83 g), BP35650*4-SKI-19-2-KNG-0-SKI-0 (25.60 g), and BP35650*4-SKI-22-3-KNG-0-SKI-0 (24.83 g). The number of filled grains per panicle has a strong correlation with the yield in this research. In contrast, panicle length and weight of 1000 grains had a weak or even negative relationship with results. These findings provide a basis for selecting potential strains that have high productivity and support efforts to develop superior rice varieties.

Abstract

Rice is the staple food for 90% of the Indonesian population, yet its grain Zn content is generally low, contributing to potential micronutrient deficiencies. Japonica rice, known for its sticky texture, has the potential to contain higher Zn levels, making it a promising candidate to support the national stunting prevention program. This study aimed to evaluate the morphological variation of high-Zn Japonica rice lines cultivated in irrigated lowland fields and to identify lines that outperform existing varieties. A single- factor Randomized Complete Block Design (RCBD) was used, consisting of 56 lines and 4 control varieties, with two replications, resulting in 120 experimental units. Observed variables included plant height, number of productive tillers, flowering time, maturity time, and panicle length. Data were analyzed using the F-test, followed by the Least Significant Increase (LSI) test at a 5% significance level when significant effects were detected. Line IR 134409-B-41-1-1 had the tallest plants, averaging 103.75 cm. The highest number of productive tillers was found in IR 134422-B-26-1 (32.75 tillers). The earliest flowering was observed in IR 134422-B-37-1 (58 days after sowing), and the earliest maturity in IR19K1059 (92 days). The longest panicle length was recorded in B14806D-MR-6-4-KN-5 (26.17 cm). Line IR 134421-B-31-1 showed high potential with a dry milled grain yield of 7.53 tons/ha and a Zn content of 31.15 ppm, closely matching the control Inpari IR Nutri Zinc
