“…We found that moderate tolerant variety, Inpara 8 had best grain yield and agronomic performance under excess iron compared to the tolerant variety, Cilamaya Muncul (Figure 3). This can be explained that Inpara 8 had been designed for targeted in swampy agroecological zone, where iron toxicity is main problem (Zarwazi et al 2016;Rumanti et al 2016). This finding is also strengthen our experience that cultivating Inpara 8 in iron hot spot farm of swampy area in South Sumatera also showed mild reaction of leaf bronzing.…”

<p>Iron toxicity affects the growth and yield of rice plant. Overcoming the damage of rice production by iron toxicity requires furthermore researches from laboratory to field levels. Here, we study responses of rice genotypes to iron toxicity between vegetative stage in hydroponic and whole grow stages in the pot. The first experiment was hydroponic experiment using twelve rice genotypes which were growth in the Yoshida Solution with addition of 0.2 % of agar. Three level of iron was given at 0, 500 and 700 ppm. The second experiment was the pot experiment using alluvial soil added with 3.000 ppm of ferrous combine with four levels of potassium and the control on Cilamaya Muncul (tolerant), Inpara 8 (moderate tolerant) and IR 64 (susceptible). In hydroponic experiment, even though the symptom appeared obviously, the leaf bronzing score (LBS) of tolerant and sensitive genotypes were not different. Physiological traits were significantly affected by Fe treatment in all varieties. Then symptom and physiological traits were significantly correlated. Through the pot experiment, it was confirmed the tolerance of each varieties. However, we couldn’t see the correlation between the LBS on hydroponic and soil at this time. And the heading delay was new finding, but it depended on varieties. We also could see the possibility of potassium application to inhibit iron toxicity but still we need to explore how it works. <br />Kata kunci: iron toxicity, rice, hydroponic, soil</p>

“…Inpara 8, a high-yielding rice cultivar is widely cultivated and grows well in tidal swamp of South Sumatra [15]. Inpara 8 derived from a double cross of Cinglonik/IRBB7//Memberamo/IR64 [9] was used as Sub1 donor parent for submergence tolerance. In our previous study [14], the recipient parent Inpago 5 showed drought tolerance in generative phase and high-yield under non-tidal cultivation.…”

“…Sub1A, Sub1B, Sub1C, but only Sub1A gene was found in submerged tolerant cultivar, FR13A. Inpara 8 has the Sub1A gene inherited by FR13A [9]. Sub1A will slackens the ethylene production and GA responsiveness during submerged condition, maintains carbohydrate reserves, and significantly elongates endurance [10].…”

Submergence stress and drought stress are main abiotic constraints encountered in South Sumatra swampland rice cultivation area. The development of new abiotic stress tolerant varieties through the introgresion of tolerance genes, such as the Sub1 gene (submergence tolerance) by using Marker-assisted Backcrossing (MABC method) is one of an ideal solution to obtain an adaptive rice variety for those conditions. The study was carried out at Faculty of Agriculture, Sriwijaya University, Indonesia. In this study, BC2F1 used as the plant materials derived from backcross performed in BC1F1 and the recipient parent, Inpago 5. Previously, BC1F1 obtained from backcrossed progenies from Inpara 8 (inherited Sub1A gene) and Inpago 5 as recipient parent, a drought tolerant variety. The main objective of this study was to analyze the Sub1 introgressed plants in backcrossed progeny BC2F1 that closest similarity to recipient parent. The result showed that Sub1 introgression was confirmed by a tightly linked Sub1 gene marker, SUB1C173 marker. Out of 47 plants, 20 plants were selected based on foreground selection. Those plants were further analyzed on background selection by using 13 SSR markers. Based on the foreground and background selection, two plants, viz, plant no. 41 and 44, were selected and will be used for further study.

Peran varietas unggul bersama pemupukan dan tata air terhadap peningkatan produktivitas sangat tinggi. Oleh karena itu upaya peningkatan produktivitas padi di lahan rawa lebak tengahan dilakukan dengan mengintegrasikan varietas unggul dengan pemupukan dan tata kelola air. Percobaan induk berupa pengenalan 10 genotipe unggul padi, dengan pemupukan optimal serta tata kelola air memanfaatkan mini polder telah dilakukan di Kabupaten Hulu Sungai Utara, Provinsi Kalimantan Selatan. Rancangan yang digunakan adalah rancangan acak kelompok dengan tiga ulangan. Percobaan anak dilakukan di 10 lahan petani dengan teknik budidaya sesuai kebiasaan petani. Penilaian terhadap genotipe dilakukan menggunakan kuisioner dan metode seleksi partisipatif. Hasil penelitian menunjukkan bahwa komponen hasil dan bobot hasil genotipe yang ditanam di percobaan induk lebih baik dibandingkan di percobaan anak. Kedua metode penilaian genotipe, menghasilkan penilaian yang cukup konsisten. Tiga varietas disukai oleh sebagian besar responden, yaitu Inpara 3, Tapus, dan Inpara 8 Agritan. Beberapa aspek yang perlu diperhatikan dalam perakitan dan pengembangan varietas padi di lahan rawa lebak antara lain vigor tanaman, jumlah anakan produktif, bentuk dan warna gabah, umur tanaman dan ketahanan terhadap penyakit. Kata kunci: preferensi, rawa lebak, seleksi partisipatif, varietas unggul
