Hybrid Vigour and Hybrid Mimics in Japonica Rice

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’

Identification of QTLs for seed storability in rice under natural aging conditions using two RILs with the same parent Shennong 265

Journal of Integrative Agriculture, 2017
Seed storability (SS) is an important trait for agronomic production and germplasm preservation in rice (Oryza sativa L.). Quantitative trait locus (QTL) for seed storability in three storage periods was identified using two sets of recombinant inbred ...

Golden Indica and Japonica Rice Lines Amenable to Deregulation [PDF]

Plant Physiology, 2003
AbstractAs an important step toward free access and, thus, impact of GoldenRice, a freedom-to-operate situation has been achieved for developing countries for the technology involved. Specifically, to carry the invention beyond its initial “proof-of-concept” status in a Japonica rice (Oryza sativa) cultivar, we report here on two transformed elite ...

Study of Rhizosphere Microbial Community Structures of Asian Wild and Cultivated Rice Showed That Cultivated Rice Had Decreased and Enriched Some Functional Microorganisms in the Process of Domestication

Diversity, 2022
Asian cultivated rice (Oryza sativa L.), domesticated from Asian wild rice, is a staple food crop for populations around the world. Asian cultivated rice has undergone physiological changes in the process of its evolution from Asian wild rice, and the ...

Genetic diversity and elite gene introgression reveal the japonica rice breeding in northern China

Journal of Integrative Agriculture, 2015
Abundant genetic diversity and rational population structure of germplasm benefit crop breeding greatly. To investigate genetic variation among geographically diverse set of japonica germplasm, we analyzed 233 japonica rice cultivars collected from ...

Comparative proteomic analysis of indica and japonica rice varieties [PDF]

Genetics and Molecular Biology, 2014
Indica and japonica are two main subspecies of Asian cultivated rice (Oryza sativa L.) that differ clearly in morphological and agronomic traits, in physiological and biochemical characteristics and in their genomic structure. However, the proteins and genes responsible for these differences remain poorly characterized.
