Abstract

The experiment was aimed at identifying QTL (quantitative trait loci) controlling ten traits of yield, yield component and plant morphology of rice based on BC1F1 of IR75862-206-2-8-3-B-B-B//IR64 mapping population consisted of 115 plants.  It was arranged in Completely Randomized Design with three replicates.  Ninety three SSR markers spread across the twelve rice chromosomes were used to map the QTL.  These markers were mostly segregated according to Mendel Law except for fourteen markers.  There were eleven QTL detected in eight traits, i.e., heading date, flag leaf length, plant height, panicle length, panicle weight, seed set, weight of 100 grains, and grain weight per plant, meaning that one or two QTL were detected in each trait.  These QTL were located at chromosome 2, 3, 4, 6, 11, and 12.  Some QTL were located at the same chromosome even at the same location indicating the close association of the traits.  It also indicated that there were common QTL which were found across genetic background and specific QTL which were found at specific genetic background.  Further study was prospective for the molecular marker application in rice improvement.   Key words: QTL, agronomic traits, SSR, rice

Abstract

In addition to carbohydrates, rice contains other minerals that function to growth and development of vital human organs. On the other hand, the content is influenced by genetic and milling processes. Indonesian Centre of Rice Research (ICRR) has genetic collection resistant to strains of the brown plant hopper (BPH). Genotypes were studied to assemble the pest-resistant varieties with high iron (Fe) and zinc (Zn) content. This study aims to determine the BPH-resistant lines that had high and stable Fe and or  Zn content. The study was conducted in XRF Laboratory, ICRR Sukamandi, West Java in 2015. Fe and Zn were determined by using XRF machine with a system of performance-based X-ray. Total 20 rice lines that resistant to BPH was used Fe and Zn content on brown and polished rice were evaluated duplo. The results showed that milling generally decreased the content of Fe and Zn at rate 56.31% and 20.54%, respectively. The highest Fe content was found in BP19564b-WBC-1-1-4-3 (12.25 ppm), while the highest Zn content in BP19564b-WBC-1-9-8-3 (26.35 ppm). Genotype BP19564b-WBC-1-9-4-2 and BP19564b-WBC-1-9-8-3 exhibited the lowest in reduction Fe and Zn content, respective, from brown to polished rice.

Abstract

Cekaman kekeringan hampir terjadi setiap tahun pada sawah tadah hujan. Salah satu teknologi untuk mengatasinya adalah dengan penanaman padi toleran kekeringan. Perakitan varietas toleran kekeringan terus dilakukan dengan mengevaluasi galur-galur yang ditujukan untuk stress kekeringan. Penelitian ini bertujuan untuk menyeleksi, mengevaluasi penurunan hasil, dan mengetahui indeks sensitivitas cekaman kekeringan pada galur-galur tadah hujan hasil seleksi generasi lanjut. Percobaan seleksi cekaman kekeringan dilakukan pada Maret – November 2016 dengan materi genetik sebanyak 135 galur dan Cek Mekongga yang ditanam pada kondisi stress kekeringan (61-72 centibar/Kpa) dan evaluasi galur – galur terseleksi dilakukan pada Februari – Juli 2017 dengan menggunakan rancangan acak kelompok 3 ulangan. Hasil kegiatan seleksi memperoleh sebanyak 19 galur terbaik memiliki toleransi terhadap stres kekeringan untuk dilanjutkan pada kegiatan evaluasi lebih lanjut di kondisi sawah tadah hujan kondisi optimum. Hasil penelitian evaluasi 19 galur menunjukkan sebanyak 4 galur toleran yaitu BP17586-2-0-JK-3-IND-2-SKI-10-PWK-1-SKI-2 (ISK 0.49), BP18354-1-2-JK-3-IND-1-SKI-3-PWK-1-SKI-1 (ISK 0.49), BP18360-2-3-JK-1-IND-1-SKI-7-PWK-2SKI-1 (ISK 0.16), dan BP18406c-JK-1-IND-0-SKI-3-PWK-2-SKI-1 (ISK 0.1). Galur BP18354-1-2-JK-3-IND-1-SKI-3-PWK-1-SKI-1 (Y = 4,77 ton ha-1) adalah galur terbaik yang memiliki potensi hasil tinggi lebih baik dari cek Inpari 38 Tadah Hujan dan memiliki toleransi terhadap cekaman kekeringan. Galur ini potensial untuk diuji lebih lanjut dan dikembangkan di sawah tadah hujan.                                                     ABSTRACTDrought stress almost occurs every year in rainfed rice fields. One of the technologies to overcome is by planting drought tolerant varieties rice. Therefore, the assembly of drought tolerant varieties is carried out continuously by evaluating lines intended for drought stress. This study aimed to select, evaluate the decline in yield, and determine the drought tolerance index of rainfed lines resulting from advanced generation selection. Study-1 of drought stress selection experiment was carried out in WS 1 2016 (March – November) with 135 genetic lines and Mekongga as susceptible checks and Inpari 38 as resistant check planted in drought stress conditions (61-72 centibar / Kpa), and study-2 was an evaluation of selected strains carried out in WS 1 2017 (February – July) with 19 selected lines and 3 checks (Mekongga and Ciherang as susceptible check and Inpari 38 as resistant checks) by using a randomized block design with 3 replications. The results of the selection activities (Study-1) obtained as many as 19 of the best lines which had tolerance to drought stress and these lines were continued in further evaluation activities in rainfed lowland with optimum conditions (Study-2). The results showed that 4 of 19 lines were tolerant namely BP17586-2-0-JK-3-IND-2-SKI-10-PWK-1-SKI-2 (DSI - drought stress sensitivity index = 0.49), BP18354-1 -2-JK-3-IND-1-SKI-3-PWK-1-SKI-1 (DSI 0.49), BP18360-2-3-JK-1-IND-1-SKI-7-PWK-2SKI-1 (DSI 0.16), and BP18406c-JK-1-IND-0-SKI-3-PWK-2-SKI-1 (DSI 0.1). The BP18354-1-2-JK-3-IND-1-SKI-3-PWK-1-SKI-1 (Y = 4.77 tons ha-1) line was the best strain that had the potential for high yield better than the Inpari 38 Rainfed Check and had tolerance to stress. This strain has the potential to be further tested and developed in rain-fed rice fields.
