Abstract
Autotetraploid rice is a type of germplasm developed from the whole genome duplication of diploid rice, leading to large grains, high nutrient content, and resistance. However, its low fertility has reduced yield and hampered commercialization. To address this issue, a new type of high fertility tetraploid rice was developed, which may serve as a useful germplasm for polyploid rice breeding. In this review, we summarize the progress made in understanding the cellular and molecular genetic mechanisms underlying the low fertility of autotetraploid rice and its F1 hybrid, as well as the main types of new tetraploid rice with high fertility. Lastly, the idea of utilizing the multi-generation heterosis of neo-tetraploid rice in the future is proposed as a reference for polyploid rice breeding.
