Breeding strategies for increasing yield potential in super hybrid rice [PDF]
, 2015 Super hybrid rice breeding is a new breeding method combining semi-dwarf breeding and heterosis breeding using germplasm and gene-environment interactions. This paper reviews the breeding strategies of super hybrid rice breeding in China, focusing on the

Performance of super hybrid rice cultivars grown under no-tillage and direct seeding
Scientia Agricola, 2012 Good progress has been made in the super hybrid rice (Oryza sativa L.) breeding in China. However, rice yield not only depends on the genetic characteristics but also on the agronomic practices.

Combining Ability and Heterosis for Grain Yield and its Component Traits in Rice(Oryza sativa L.)
Notulae Scientia Biologicae, 2013 The nature and magnitude of heterosis and combining ability was studied in 18 F1 hybrids involving three CMS lines and six testers using line × tester analysis. The analysis of variance for combining ability of all the traits showed that variances due to

Dissecting the genetic basis of the heterosis of Y900, an elite super-hybrid rice
bioRxiv, 2022 Y900 is one of the top hybrid rice varieties with a yield exceeding 15 t/hm2. To dissect the mechanism of heterosis, the male parent line R900 and female parent line Y58S were sequenced using long-read and Hi-C technology.

Genomic Prediction of Yield Traits in Single-Cross Hybrid Rice (Oryza sativa L.)
Frontiers in Genetics, 2021 Hybrid rice varieties can outyield the best inbred varieties by 15 – 30% with appropriate management. However, hybrid rice requires more inputs and management than inbred rice to realize a yield advantage in high-yielding environments. The development of
