Abstract Background Long noncoding RNAs (lncRNAs) have several known functions involving various biological regulatory processes in plant. However, the possible roles of lncRNAs during peanut seed development not been fully explored. Results In this study, two recombinant inbred lines (RIL 8 ) that differ size were used to investigate comprehensive lncRNA profiles derived from at 15 and 35 days after flowering (DAF). We identified a total 9388 4037 novel lncRNAs, which 1437 differentially expressed lncRNAs. Interestingly, expression patterns number can be very different between closely related these predominantly only one RIL DAF. Some found putative cis-acting target genes predicted involved transcription, transport, cell division, plant hormone biosynthesis. The representative 12 protein-coding validated by qPCR. Same pattern was observed most their genes. 11 XR_001593099.1, MSTRG.18462.1, MSTRG.34915.1, MSTRG.41848.1, MSTRG.22884.1, MSTRG.12404.1, MSTRG.26719.1, MSTRG.35761.1, MSTRG.20033.1, MSTRG.13500.1, MSTRG.9304.1 may play key development. Conclusions These results provided new information on lncRNA-mediated development, contributing understanding molecular mechanisms
