Sugarcane (Saccharum spp.) plays a crucial role in global sugar production; however, the efficiency of breeding programs has been hindered by its heterozygous polyploid genomes. Considering non-additive genetic effects is essential in genome prediction (GP) models of crops with highly heterozygous polyploid genomes.

- Smut disease significantly reduces sugarcane yields, and using resistant varieties is the most effective control method.
- Researchers identified a Japanese wild sugarcane, 'Iriomote8', that has strong resistance to smut disease and conducted QTL analysis with its offspring to find genetic markers associated with resistance.
- They found a key QTL on linkage group 8 that accounts for around 50% of smut disease incidence, indicating it can be utilized in marker-assisted selection to enhance disease resistance while maintaining other desirable plant traits.
Methane (CH) is a greenhouse gas, and paddy fields are one of its main anthropogenic sources. In Japan, country-specific emission factors (EFs) have been applied since 2003 to estimate national-scale CH emission from paddy field. However, these EFs did not consider the effects of factors that influence CH emission (e.

To mitigate this emission based on effective management measures, CH4 emission from paddy fields must be quantified at a national scale. In Japan, country-specific emission factors have been applied since 2003 to estimate national CH4 emission from paddy fields.
