Frequencies of various types of abnormal ovules and embryo sacs in the OsIG1-RNAi repression lines (60 spikelets examined for each line were collected at the mature stage)
| Genotype | One ovule | Double ovules | Total ovules examined | ||||||||

ESD, embryo sac degeneration; ESE, embryo sac with an extra egg cell; ESWA, embryo sac with abnormal polar nuclei; NES, normal embryo sac; OAT, other abnormal types.
