“…Mutants that are similar in yield with wild type but having an early maturing nature are very useful for the rice varietal improvement programme. Similarly, Chakrabarti et al [ 57 ] developed early maturing PNR series mutants utilizing gamma radiations in Basmati 370 PNR-17-3 and Mustikarini et al [ 58 ], developed a gamma-ray induced red rice ( Celak Madu accession) mutant which matures earlier than the wild type (i.e., in 115 days) and is drought tolerant.…”

To create novel variants for morphological, physiological, and biotic stress tolerance traits, induced mutations were created using Ethyl Methane Sulphonate (EMS) in the background of Samba Mahsuri (BPT 5204), a popular and mega rice variety of India. A population derived from 10, 500 M1 plants and their descendants were phenotyped for a wide range of traits leading to the identification of 124 mutants having variations in key agro-morphological traits, and 106 mutants exhibiting variation for physiological traits. Higher yield is the ultimate goal of crop improvement and we identified 574 mutants having higher yield compared to wild type by having better yield attributing traits. Further, a total of 50 mutants showed better panicle exertion phenotypes as compared to Samba Mahsuri leading to enhancement of yield. Upon rigorous screening for three major biotic stresses, 8 mutants showed enhanced tolerance for yellow stem borer (YSB), and 13 different mutants each showed enhanced tolerance for sheath blight (ShB) and bacterial leaf blight (BLB), respectively. In addition, screening at multiple locations that have diverse field isolates identified 3, 3, and 5 lines for tolerance to ShB, YSB and BLB, respectively. On the whole, 1231 desired mutant lines identified at M2 were forwarded to an advanced generation (M5). PCR based allele mining indicated that the BLB tolerant mutants have a different allele than the reported alleles for well-known genes affecting bacterial blight resistance. Whole genome re-sequencing revealed substantial variation in comparison to Samba Mahsuri. The lines showing enhanced tolerance to important biotic stresses (YSB, ShB and BLB) as well as several economically important traits are unique genetic resources which can be utilized for the identification of novel genes/alleles for different traits. The lines which have better agronomic features can be used as pre-breeding lines. The entire mutant population is maintained as a national resource for genetic improvement of the rice crop.

Black rice (Oryza sativa L. indica) is a functional food with high anthocyanin and dietary fiber content. Drought conditions due to significant climate change can reduce black rice production. Mutation induction using gamma-rays is among the popular approaches to plant improvement with increased genetic variability for breeding. The research aims to determine the growth, yield, and obtain drought-tolerant mutant black rice. This study used a field experiment method. It planted four selected mutant lines and control plants for each local black rice variety, Bantul, and Boyolali. The results showed that drought stress degraded growth and yield character, such as plant height, shoot dry weight, the number of productive tillers, percentage of filled grain, and inhibited flowering age. Resistance evaluation to drought stress used the stress sensitivity index (SSI). M4-By-200-01, M4-By-200-04, and M4-By-200-04 lines could become short-stemmed black rice and were tolerant to drought stress.

“…The detection of plant character in response to drought stress can use root organ development (Seo et al 2020), leaf anatomy (Zagoto and Violita 2019), leaf rolling, and leaf dryness (IRRI 2013). The selection method using stress in the critical period obtained the M5-GR150-1-9-13 line of red rice that was drought tolerant (Mustikarini et al 2016). Drought stress applied to the booting stage showed the most significant effect on decreasing various parameters of the selection of drought-tolerant rice lines (Mustikarini et al 2017).…”

Abstract. Mustikarini ED, Lestari T, Santi R, Prayoga GI, Cahya Z. 2022. Short Communication: Evaluation of F6 generation of upland rice promising lines for drought stress tolerance. Biodiversitas 23: 3401-3406. Water is important in metabolic processes affecting rice crop growth and development. Drought stress can decrease rice production, necessitating the development ofdrought-tolerant varieties. Selection of drought-tolerant can be done during the critical period plant booting phase. Thisresearch aimed to determine promising linesof upland rice tolerant to drought stress. This research was conducted from December 2019 toMay 2020 at the experimental farmofthe Faculty of Agriculture, Fisheries and Biology, Universitas Bangka Belitung. The research was laid out in a completely randomized design with a single-factortreatment. The treatment was rice genotypes consisting of 10 lines and 2 checkvarieties; each was 3 replicates. The results showed that the droughtstressin the plant booting phase of rice plants significantly affected the plant heigh character of the plant, grains number per panicle, the weight of grain per panicle, the age of flowering, and harvest time, but gave no significant effect on the number of leaves, the number of productive tillers, roots length. The upland rice lines 23A-56-30-25-1, 23A-56-30-25-12, and 23A-56-30-25-13 showed good drought stress tolerance based on leaf rolling, leaf drying, crop yield, and plant growth percentage.
