Abstract. Nurhidayah S, Purwoko BS, Dewi IS, Suwarno WB, Lubis I. 2023. Agronomic performance and selection of green super rice doubled haploid lines from anther culture. Biodiversitas 24: 819-826. Rice is the staple food of most Asian, including Indonesian people. Plant breeding plays an important role in producing high-yielding varieties of rice to meet national carbohydrate sufficiency. Green Super Rice (GSR) is an alternative for rice variety development that has the advantages of high yield, good quality, pest resistance, and efficient fertilizer use to support sustainable agriculture. This study aimed to evaluate the agronomic character of GSR doubled haploid (DH) lines derived from anther culture and determine the best GSR rice lines based on index selection. The treatment was 65 genotypes consisting of 60 DH of GSR lines from anther culture of 5 combinations of crosses and 5 check varieties. The study used a randomized complete block design with three replications. The results showed that most of the tested lines had similar agronomic performances to the check variety Inpari 42 Agritan GSR. Almost all agronomic characters of the GSR DH lines had high genetic variability. Most characters had a high category of broad-sense heritability except panicle length. Line selection using index selection for economically important agronomic characters yielded 27 GSR DH lines having high productivity, number of productive tillers per hill, number of total grains per panicle, and percentage of filled grains per panicle.

Abstract. Hadianto W, Purwoko BS, Dewi IS, Suwarno WB, Hidayat P. 2023. Selection index and agronomic characters of doubled haploid rice lines from anther culture. Biodiversitas 24: 1511-1517. Development of superior rice varieties requires selection of the best lines having good agronomic characters and high yields. This study aimed to select high-yielding doubled haploid rice lines obtained from anther culture through index selection and agronomic characters. The study was conducted using a single-factor randomized complete block design (RCBD) with genotype as treatment. Sixty doubled haploid lines and 5 check varieties were evaluated along with three replications, hence, the total experimental unit was 195. Analysis of variance showed that the genotypes had a significant effect on all observed characters, except for the number of productive tillers. The agronomic characters observed had a high broad sense of heritability, except for the number of productive tillers which was in the medium category. Furthermore, index selection was carried out based on productivity, the number of productive tillers, the total number of grains, as well as the percentage of filled grains. Based on the index selection, 29 lines were selected among the 60 doubled haploid rice lines tested. These lines had the range in productivity from 2.95 to 6.77 ton ha-1, the number of productive tillers from 12.3 to 20.8 tillers, the total number of grains from 135 to 275.4 seeds, the filled grain percentage from 53.23 to 87.61%, and the selection index from -1.48 to 7.88. The selected lines will be further tested at the next experimental stage in several locations to produce high-yielding, brown planthopper-resistant, and drought-tolerant rice varieties.

Abstract. Romadhon MR, Sobir, Suwarno WB, Matra DD. 2024. Profile microsatellite mining of whole genome sequencing and transcriptomic assembly in dwarf and tall areca nut (Areca catechu L.) in Indonesia. Biodiversitas 25: 1081-1088. Areca nut (Areca catechu L.) has high diversity in fruit shape and flowering time. Two superior varieties are commonly cultivated in Indonesia, namely Betara areca nut (tall) and Emas areca nut (dwarf). Molecular level diversity from genomic and transcriptome of areca nut data is available at NCBI, but not yet for Indonesian areca nut. The research compared the results of SSR with two method approaches to detect genetic diversity in the plants accurately. This study aimed to compare the SSR motifs of Betara areca nut and Emas areca nut varieties from whole genome sequencing and transcriptome assembly. The research was conducted at the Leuwikopo Seed Centre Laboratory of the IPB University, Bogor, Indonesia. The methods used are Whole Genome Sequencing (WGS) and transcriptome assembly. A total number of identified SSRs from WGS approach from Betara areca nut of 95 SSRs and Emas areca nut of 95 SSRs, while Betara areca nut SSRs from transcriptome assembly of 466 SSRs and Emas areca nut of 357 SSRs. The percentage of contigs and transcripts from Betara areca nut containing SSR was 7.43% and 4.22%, respectively, while Emas areca nut was 8.06% and 2.04%, respectively. AT is the dominant SSR motif in WGS, while the GA motif dominates the transcriptome assembly results.
