Transmission: PepMV is very efficiently transmitted mechanically, and a low seed transmission rate has been demonstrated.

The breeding of polyploid rice made no breakthrough for a long time because of low seed set.

Because low seed set rates in polyploid rice usually makes it difficult to breed, the selection of Ph-liked gene lines was emphasized.

Lau began the event as a low seed and was forced to take part in seven rounds through difficult weather conditions and wave heights.

This showed a strong linkage drag of low seed oil content, which was controlled by the five qEA-independent qOCs, with low seed erucic acid content.
