Abstract. Akbar MR, Purwoko BS, Dewi IS, Suwarno WB, Sugiyanta, Anshori MF. 2021. Agronomic and yield selection of doubled haploid lines of rainfed lowland rice in advanced yield trials. Biodiversitas 22: 3006-3012. Selection process is important step to obtain high yielding variety. This study aimed to obtain information on agronomic performance of doubled haploid lines of rainfed rice in advanced yield trials and select the best lines for multi-location yield trials. Two experiments were conducted in Bogor and Subang using a randomized complete block design for each location and consisted of 35 doubled haploid lines and two check varieties namely Ciherang and Inpari 18 as a treatment. The result revealed that interaction between genotype and environment (G x E) significantly affected all agronomic characters, except on the panicle length. Characters with high heritability value were all agronomic characters except number of productive tillers and productivity. Genotypic correlation analysis showed that number of productive tillers and weight of 1000 grains had significant and positive correlation with productivity. The selection used weighted selection index based on multivariate analysis. Fourteen lines were selected for multi-location yield trials. These lines had characteristics as follows: number of productive tillers (14.0-17.7 tillers), weight of 1000 grains (24.7-32.5 g), and productivity (5.0-6.2 ton ha-1). The selected lines can be evaluated further to obtain superior lines in multi-location trials.

Abstract. Akfindarwan AK, Farid M, Syaiful SA, Anshori MF, Nur A. 2023. Selection criteria and index analysis for the S2 maize lines of double-crosses. Biodiversitas 24: 192-199. This study aimed to determine the selection criteria and the selection index for the S2 maize lineage from double cross crosses and to select the potential lines that could be continued in the S3 generation. The research was carried out in the field from July to November 2020 at the Experimental Farm of the Agriculture Faculty, Hasanuddin University, Tamalanrea District, Makassar City, South Sulawesi. The maize lines used were derived from 4 double cross populations of S1 generation, namely: DC1 (P36/B9//NK7328/JH2) with 19 genotypes, DC2 (B9)/HJ28/NK728), DC3 (B18/B2/B2/N29), and DC4 (JH45/B19/N29/B2). The results of this study revealed that the selection criteria suitable for this population were the weight of seeds per cob, peel cob weight, and weight of 100 seeds. Furthermore, the selection index analysis showed that there were 61 promising lines for F2 double cross maize that had a positive index value, while based on the Z value, there were 44 lines that had a better index value than the best parents. Therefore, it is recommended that the 61 S2 Maize lines from double crosses be further tested on to the S3 generation.

Abstract. Haring F, Farid M, Ridwan I, Anshori MF, Fadhilah AN, Hartanto KB. 2024. Polyploidization of three Chrysanthemum varieties in vitro at various levels of colchicine soaking length. Biodiversitas 25: 3496-2503. The demand for new types and varieties of chrysanthemums with unique characteristics, such as various colors, shapes, and sizes, continues to increase. One approach that can be taken to achieve this diversity is through mutation techniques using chemical mutagens such as colchicine to obtain polyploid plants. This research, which aims to determine the best varieties and soaking time for colchicine in forming polyploid plants in vitro, has the potential to impact the field of Chrysanthemum breeding significantly. The research was arranged in a split-plot design (SPD), with the main plot being the Chrysanthemum variety (v), consisting of the Pinka Pinky (v1), Lollipop (v2), and Maruta (v3) varieties. The subplot is the soaking time at a colchicine concentration of 0.05%, which consists of 0 hours (t0), 4 hours (t1), 8 hours (t2), and 12 hours (t3). The parameters observed were the number of shoots, number of leaves, number of roots, time to sprout, time to root, time to form plantlets, and polyploidy analysis. Chromosome doubling in chrysanthemum plants after 0.05% colchicine induction with different soaking times produced mixoploid plants or the highest chromosome doubling of 9.18% + 18.82%, namely in the Lollipop variety with a soaking time of 12 hours. Meanwhile, other treatments did not show chromosome doubling and remained diploid but had different levels of chromosome variation.
