Table 1 Ploidy levels and parental genome ratios of rice seed components, and seed setting and embryo rescue rates from balanced and unbalanced crosses
From: Parental Genome Imbalance Causes Post-Zygotic Seed Lethality and Deregulates Imprinting in Rice
Crosses | Maternal ploidy | Embryo ploidy (m:p) | Endosperm ploidy (m:p) | Seed setting rate | Embryo rescue rate |

TH4n × TH4n | 4n | 4n (2:2) | 6n (4:2) | 14.04 % (183/1303) | 37.35 % (31/83) |
TH4n × Nip2n | 4n | 3n (2:1) | 5n (4:1) | 17.26 % (231/1338) | 48.86 % (86/176) |
Nip2n × TH4n | 2n | 3n (1:2) | 4n (2:2) | 10.05 % (255/2537) | 4.69 % (16/341) |
