Flower bud formation and flowering in chrysanthemums occur under short day conditions (SD), but the molecular basis for the switch to reproductive growth is less well understood than in model plants. Here, a spontaneous mutant able to flower under long days is described. In an attempt to reveal the pathway(s) involved in the formation of flower buds under contrasting daylengths, transcriptome sequencing was carried out in plants grown both under SD and long day conditions (LD). A number of differentially transcribed genes involved in the various known flowering pathways were identified. Both circadian clock genes and Chrysanthemum FLOWERING LOCUS T Like3 (CmFTL3) were up-regulated under SD, thereby inducing floral bud formation and flowering. The gibberellin (GA) signaling pathway-related genes Gibberellin 20-oxidase (GA20ox) and Gibberellin receptor (GID1) were up-regulated in the mutant under LD, while the catabolic genes Gibberellin 2-oxidase (GA2ox) and GA-INSENSITIVE (GAI) were down-regulated, thereby inducing the transcription of SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) and LEAFY (LFY). The GA content of the leaf was higher in the mutant than in the wild type (WT) under LD and SD, and the mutant has more branching than WT plants under LD or SD. When treated with GA, the mutant flowered earlier under both SD and LD relative to WT, but there was no detectable phenotype difference between the two lines. The indication was that the photoperiod pathway majorly regulates flower bud formation and flowering time in chrysanthemums under SD. The GA signaling pathway only plays a subsidiary role for flowering. However, the GA signaling pathway predominated for flowering under LD.

Many new hybrids of chrysanthemums from Indonesia are adapted to tropical areas. The hybrids were growing well with many characteristics such as consumer preferences and the idiotype of chrysanthemums. The goal of the research was to collect, select and categorize new chrysanthemum hybrids to be the parent’s resource for new breeding. They were Puspita Nusantara, Jayani, Cayapati, Sabiya, Swarna Kencana, Trissa, and Tadasita varieties. There were 2 categories, standard and spray types. Each of the varieties had specific novelty characteristics that could be gen resources as parents in chrysanthemum breeding. The specific and novelty characteristics as gen resources were the vase life period, flower shape, colour, number of petals, and the total number of flowers per plant. The standard type dominated white and yellow colour, and the spray type had more colour, shape, and size variations. Chrysanthemum cultivar (cv.) Swarna Kencana showed the highest plant height in a low area 187.6 meters MASL (meters above sea level). It followed cutting flower standards. Puspita Nusantara variety complied as crossing parents for resistance to Puccinia horianna.
