Hybrid Vigour and Hybrid Mimics in Japonica Rice [PDF]

Agronomy, 2022
In crop improvement programs, hybrid vigour (heterosis) is an important breeding strategy but the molecular mechanisms of hybrid vigour are still unclear. Grain yield declines after F1 generation due to phenotypic segregation. We found that, at the early seedling stage in hybrids derived from the temperate japonica rice varieties ‘Doongara’ and ‘Reiziq’

Two complementary genes in a presence-absence variation contribute to indica-japonica reproductive isolation in rice

Nature Communications, 2023
Understanding the evolutionary forces in speciation is a central goal in evolutionary biology. Asian cultivated rice has two subspecies, indica and japonica, but the underlying mechanism of the partial reproductive isolation between them remains obscure.

Molecular Breeding of Zheyou810, an Indica–Japonica Hybrid Rice Variety with Superior Quality and High Yield

Agriculture, 2023
Rice heterosis has played a significant role in improving rice yields in China since the 1970s. The utilization of heterosis between the indica and japonica subspecies of rice is especially important in this regard.

Growth Traits and Yield Performance of Japonica Hybrid Rice Bred by the New Strategy in the Yangtze River Region of China

Agronomy
Despite the successful breeding of hybrid japonica rice by the new strategy (the female parent with a restorer line containing an appropriate proportion of indica rice genes) in China, it remains unclear whether these cultivars exhibit a similar yield ...
