Abstract

Improvement upland rice lines are faced with the diversity of physical and ecobiological characteristics of dry land, including acidic-dry land. An alternative approach to optimize upland rice cultivation in acidic-dry land is the selection of adaptive varieties. The aim of this experiment was to obtain lines that have superior performance and yield on acidic-dry land, as well as good rice quality. A total of 36 lines of upland rice, including four check varieties, were selected at Tamanbogo, Lampung on rainy season (November 2017-March 2018). The genetic parameters estimation showed that flowering age, harvest age, weight of 1,000 grains and yield can be used as selection criteria. Based on these selection criteria, four lines were selected, namely B15231-MR-10-1, B15053F-PWR-2, B14908C-MR-1-25-1-3 and B15344B-TB-34. These lines had grain yields that were not significantly different from the best check variety Inpago 8 (3.84 ton ha-1), average resistant to leaf blast (score 1), highly resistant to neck blast (score 0), and moderately tolerant of Al. Additionally, these lines had medium grain with small-medium chalkiness (MMS-LMM), amylose content between 20-23% with soft-medium rice texture. One selected line, namely B15344B-TB-34, was identified as a red-pericarp rice. Keywords: aluminum toxicity, blast disease, drought, grain quality, selection criteria

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.
