Genetic Mechanism of Hybrid Sterility and Utilization of Indica-japonica Inter-subspecific Heterosis in Rice

Guangdong nongye kexue, 2022
Asian-cultivated rice (Oryza sativa L.) consists of two subspecies, indica (Oryza sativa L. indica) and japonica (Oryza sativa L. japonica) subspecies. There are considerable differences between them in morphology, physiology and gene level. The stronger

Yield, Stability, and Adaptability of Hybrid Japonica Rice Varieties in the East Coast of China

Agronomy
The high yield potential and stability of hybrid japonica rice varieties are crucial for sustainable agricultural development and food security. Rice varieties must undergo rigorous testing through multi-site regional trials before being introduced to ...

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’

Preliminary Exploration of Physiology and Genetic Basis Underlying High Yield in Indica–Japonica Hybrid Rice

Agriculture
The utilization of heterosis is of great significance in improving rice yield. To explore the physiological and genetic basis for high yield in indica–japonica hybrid rice, Zheyou18 (z18) and Yongyou12 (y12) were used as materials and compared with ...

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 ...

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.
