“…The Jeliteng cultivars are known as black cultivars with high antioxidants (Suarni et al, 2020). The antioxidant is active during the reproductive phase and causes a purplish to black color on the grains (Dwiatmini and Afza, 2018), so their tolerance to double stress is less optimal in the vegetative phase. The Salumpikit cultivar is a genotype only tolerant of drought stress.…”

Image-based phenotyping in selecting drought- and salinity-tolerant rice lines is a potential approach to complement other selection criteria. This study aimed to determine tolerance response and selection criteria on drought and salinity stresses based on a morphological and image-based phenotyping character. The experiment, set up in a screen house of the Department of Agronomy, Faculty of Agriculture, Hasanuddin University, Indonesia, consisted of a nested randomized complete group design. The nested replication included stressed environments with two factors and three repetitions. The level of environmental stresses comprised the first factor, i.e., normal (without NaCl and PEG), salinity (60 and 120 mM NaCl), drought (10% and 20% PEG), and combination of drought-salinity (10% PEG + 60 mM NaCl). The second factor entailed the rice genotypes. Observations of the morphological and image-based phenotyping characters ensued. The results indicated that salinity stress had a wider diversity than drought stress, while the multiple stresses had a relatively stable variety compared with single stress. Morphological and image-based phenotyping character increased precision in assessing the tolerance or adaptability of rice to drought stress, salinity, and its combination. The morphological characters that can serve as rice selection criteria in a combination of drought-salinity stress included the shoot and root fresh weights and the root length. As for the image-based phenotyping character, the shoot phenotype width can serve as the selection criterion. Image-based phenotyping characters, especially the shoot phenotype area, were recommended as criteria for precise selection in assessing rice genotypes’ potential tolerance and adaptability to drought stress, salinity, and its combinations.

“…Masyarakat kini mulai mementingkan kesehatannya sehingga lebih menyeleksi bahan pangan yang dapat mencukupi kebutuhan gizi mereka (Utami, 2021). Padi fungsional merupakan bahan pangan pokok dengan kandungan gizi tinggi yang berguna untuk kesehatan (Dwiatmini & Afza, 2018). Selain memiliki kandungan energi, serat, protein, lemak, dan mineral, padi fungsional mengandung antosianin yang ditandai dengan adanya pigmen warna merah dan ungu pekat.…”

Melonjaknya tingkat konsumsi masyarakat dan penurunan luasan lahan budidaya mengharuskan petani untuk berinovasi. Salah satu upaya peningkatan produksi pangan sehat adalah memanfaatkan padi fungsional dengan metode budidaya soilless. Tujuan penelitian ini adalah untuk mengkaji perbandingan air dan sekam yang terbaik dalam budidaya soilless pada dua varietas padi fungsional. Penelitian ini menggunakan rancangan acak lengkap faktorial (RALF) dengan 2 faktor dan 3 ulangan. Faktor pertama yaitu media soilless air dan sekam dengan perbandingan 6:1, 8:1, 10:1, 12:1, dan 14:1, sedangkan faktor kedua yaitu varietas Watu dodol A3 dan Merah A2. Hasil penelitian menunjukkan bahwa media soilless air dan sekam 8:1 memberikan performa tertinggi pada jumlah gabah permalai (231,50 bulir) dan jumlah gabah bernas permalai (205,67 bulir). Selain itu terdapat perbedaan yang signifikan pada tinggi tanaman, anakan produktif, dan panjang malai antara Watu dodol A3 dengan Merah A2.

“…Pratiwi and Purwestri (2017) have documented 24 varieties of black rice from Java, Nusa Tenggara, Sulawesi and Kalimantan. Meanwhile, Dwiatmini and Afza (2018) have used 27 types of red rice originating from various regions in Indonesia such as Kalimantan, Java, Sumatra, Riau, and East Nusa Tenggara to conduct research on anthocyanin content in rice accessions. Afza (2016) reported that there were 54 accessions of brown rice preserved at the Center for Research and Development of Agricultural Biotechnology and Genetic Resources, Bogor.…”

Research on rice plant breeding to get superior black rice varieties with tender rice texture can be carried out by crossing Black Rice and Mentik Wangi variety. The rice lines derived from a crossing of these two varieties have recently reached the F6 line. The texture of rice is distinguished by the amylose content. The lower of the rice amylose, the more tender of the rice texture, and vice versa. This study aimed to find out the profile of amylose content and the grains morphology of the lines that will be developed as waxy pigmented rice. Analysis of amylose content was carried out using iodine-colorimetry methods. The quantification of amylose was measured based on the regression of the standard amylose curve. The results showed that all the F6 lines had the potential to be developed as waxy pigmented rice. Based on the Kruskall Wallis test, there was a variance in the amylose profile average of the eight genotypes. In terms of grains morphology, the line 482-17-7 and 482-17-18 had a combination colour between the two parents. In addition, there was a significant difference in grains size between the genotypes and the grain size of all lines were classified in the medium size. F6 lines resulted from the crossing between Black Rice and Mentik Wangi are recommended to be used as superior varieties of waxy pigmented rice.
