Germplasm Phenotype:

• CS72560  — defects in small RNA accumulation
• CS72563  — partial complementation of small RNA accumulation
• SAIL_260_A03  — A proportion of pre-meiotic ovules have two MMCs and have several abnormally enlarged sub-epidermal cells.Plants are fertile and show no signs of ovule or seed abortion.
• SAIL_34_G10  — Abnormal megagametophyte formation. Many megaspore type cells form but do not progress to make embryo sacs.
