Variety traits

Rice shattering

Oryza sativa L.

A trait characterizing the ability of caryopses to remain attached to the panicle after reaching biological maturity. It determines harvesting losses and must be considered when scheduling field operations.

In the reference 13 varieties crop Rice, where this is mentioned in the description.

Rice shattering directly affects crop yield volumes, as varieties with low resistance to this trait are susceptible to significant losses if left standing in the field too long or when exposed to adverse weather conditions, such as strong winds. High resistance to shattering allows agronomists to widen the window for completing harvesting at optimal times.

In breeding practice and state variety testing, this parameter is assessed using expert visual methods or by applying mechanical stress to the panicle during full maturity. The trait is characterized qualitatively on a resistance scale, where most modern zoned varieties are classified as resistant, which is a mandatory requirement for inclusion in the registry.
