The objective of this study was to explore the heterosis of partial interspecific hybrids
between African rice (Oryza glaberrima Steud.) and Asian rice (Oryza sativa L.) and its …

Development of partial inter-specific hybrid (PIH) rice is a promising approach for exploiting
inter-specific heterosis between Oryza glaberrima and Oryza sativa. In the present study, the …

Heterosis, or hybrid vigor, represents one of the greatest contributions of genetics to the
improvement of major crops such as maize and rice, which is intensively studied and …

Utilization of heterosis has greatly contributed to rice productivity in China and many Asian
countries. Superior hybrids usually show heterosis at two stages: canopy development at …

Abstract Information on parental genetic distance and combining ability is a fundamental
prerequisite for hybrid rice breeding. Based on a study of genetic diversity using molecular …

Distant heterosis is a promising genetic phenomenon to achieve the yield ceiling of hybrid
rice. Heterosis and agronomic performance of indica rice (Oryza sativa L. ssp. indica) …

The magnitude of heterosis in F 1 hybrids is related not only to the performance of parents
per se but also to the genetic diversity between two parents. The extent of genotypic …

The inter-subspecific crossing between indica and japonica subspecies in rice have been
utilized to improve the yield potential of temperate rice. In this study, a comparative study of …

Heterosis in rice has been acknowledged to be associated with the genetic divergence of
the parents used in hybridization. We investigated the nature and extent of the correlation …

Rice is the staple food for the world and two rice species are cultivated for food production.
Oryza sativa originated in Asia but is widely grown. O. glaberrima originated and is …
