a

Embryo developmental stage names refer to the cell number or morphology of the embryo proper. Abbreviations are defined as follows: EG, early globular; LG, later globular; EH, early heart.

b

Siliques were numbered consecutively from the top of the inflorescence, such that the oldest siliques have the highest numbers.

c

Aborted seed were shrivelled with no visible embryo or endosperm development.
