Background Heterosis is widely used in agriculture. However, its molecular mechanisms are still unclear in plants. Here, we develop, sequence, and record the phenotypes of 418 hybrids from crosses between two testers and 265 rice varieties from a mini ...

SUMMARYHeterosis, also known as hybrid vigor, is the phenomenon wherein a progeny exhibits superior traits relative to one or both parents. In terms of crop breeding, this usually refers to the yield advantage of F1 hybrids over both inbred parents. The development of high‐yielding hybrid cultivars across a wider range of crops is key to meeting future

Heterosis, also known as 'hybrid vigor', is a well-known phenomenon whereby hybrid offspring resulting from cross pollination exhibit greater vigor than either parent. Here, Hochholdinger and Baldauf provide an overview of this fascinating biological phenomenon and what is known about the underlying genetics and mechanisms.

Heterosis and Hybrid Crop Breeding: A Multidisciplinary Review
Although hybrid crop varieties are among the most popular agricultural innovations, the rationale for hybrid crop breeding is sometimes misunderstood. Hybrid breeding is slower and more resource-intensive than inbred breeding, but it allows systematic ...

Nonadditive gene expression contributing to heterosis in partially heterozygous maize hybrids is predominantly regulated from heterozygous regions. [PDF]
Summary Hybrids often perform better than their homozygous parents, a phenomenon that is commonly referred to as heterosis. Heterosis is widely utilized in modern agriculture, although its molecular basis is not very well understood. In this study, we backcrossed an intermated recombinant inbred line population of maize (Zea mays L.) with its parental ...

The genetic mechanism of heterosis utilization in maize improvement
In maize hybrid breeding, complementary pools of parental lines with reshuffled genetic variants are established for superior hybrid performance. To comprehensively decipher the genetics of heterosis, we present a new design of multiple linked F1 ...

Biological pathway expression complementation contributes to biomass heterosis in Arabidopsis
Significance Heterosis, referring to the better performance of an F1 hybrid compared with its parents, has been greatly exploited in agriculture to improve yield. Nevertheless, our understanding of its genetic and molecular mechanism has remained limited.
