Abstract

Palm oil has supplied more than 30% of vegetable oil consumption worldwide. Rising demand has pushed oil palm plantations to increase the yield. It is well known that genetic has played a significant role in phenotypic performance. Moreover, in recent years, genomic data has emerged tremendously. Unfortunately on the gene related to oil palm yield. Therefore, a preliminary study to classify and select oil palm candidate genes associated with characteristic by scanning existing genes in oil palm or other in-silico species were conducted. Based on Blast2Go results, 22 genes related to oil biosynthesis, two specifically related to fruit number and fruit weight were analysed. Furthermore, 19 candidate genes were able to amplify.

Abstract

In South Sumatra the cultivation of black rice is uncommon. This is because of the lack of available land for planting which can be used to grow local black rice. Since more farmers dominate the white rice or brown rice cultivation. One effort that can be made to increase the area of local black rice planting areas is to use South Sumatra's vast swampy land. Related to the previous study, this research will be carried out by testing the growth of F1 seeds crossed by accession to high productivity local black rice and nutrition with marinated resistant Inpara 5 varieties. In quantitative parameters, the maximum average value of it was shown at the age of 12 MST plants that IM.6 plants at 145.08 as the highest average value of the crossing results. IM.6 was the highest median value with 144.5. The maximum standard deviation value was 5.06 for IT.11 plants, and the minimum value being 141.4 for IM.6 forms and 150.0.6 for IM.6 plants. The qualitative parameters consist of plant shape, stem color, leaf color, and flag leaf are seen when the plant is 6 MST or in the vegetative phase. Done by describing plants from 5 sample plants per randomly selected population. From the result of this research, there is no significant differential between accession and parental.

Abstract

Despite the importance of comprehensive genetic characterization for the conservation and utilization of local rice germplasm in breeding programs, the maternal genetic diversity of South Sumatran local rice remains largely unexplored. In this study, we evaluated the genetic diversity, maternal lineage, and phylogenetic relationships of South Sumatran rice accessions using the chloroplast trnH–psbA intergenic spacer, a highly variable chloroplast marker widely used for assessing genetic diversity and phylogenetic relationships in rice and other plant species. A total of 18 South Sumatran rice accessions, along with reference sequences, were analyzed through sequence alignment, haplotype network construction, genetic distance clustering, and phylogenetic tree reconstruction using the Neighbor-Joining (NJ) and UPGMA methods. The trnH–psbA region showed a uniform sequence length of 415 bp and low nucleotide diversity (π = 0.096%), resulting in the identification of three haplotypes. Phylogenetic and genetic distance analyses consistently identified two accessions, Bone 1 and Pegagan 2, as genetically distinct, highlighting their potential value as candidates for future conservation and breeding initiatives. These findings provide a molecular basis for the preservation and strategic utilization of South Sumatran rice germplasm and emphasize the importance of conserving genetically divergent local accessions. Future studies integrating chloroplast and nuclear markers will enable a more comprehensive assessment of genetic diversity for rice breeding and conservation.
