A majority of the commercial producers crossbreed cattle, mating parents of different breeds. They primarily use this breeding system to produce heterosis in their herds. Heterosis is often called ...

A new study of sorghum explores the genetics of heterosis, the process by which hybrid plants perform better than the parent varieties used to create them. The new study fills in some of the gaps that ...

Starting from 17 representative elite rice hybrid lines, the authors bred first and second generations to produce more than 10,000 hybrid rice lines, which they characterized for quantitative traits — ...

Tsukuba, Japan—Heterosis is a phenomenon in which F 1 hybrids, generated by crossing different species or strains, exhibit more vigorous growth than their parents. F 1 hybrids are grown for many crops ...

Inbreeding depression is defined as reduced fitness or performance arising from increasing homozygosity of progenies due to successive inbreeding, whereas heterosis refers to the superiority of a ...

Commercial sheep producers have long seen the benefits of hybrid vigour (heterosis) in cross-bred dam lines but a trend now suggests flockmasters are seeing the benefits cross-bred rams (paternal ...

I appreciate your excellent and educational work. I’m just starting out in farming, and I’m learning a lot. I appreciate the topics that have already been covered in this column; it has been a great ...

Early adopters of crossbreeding as a tool to produce the right kind of cow for their block-calving, grazing-based systems, found that longer term breeding strategies could become haphazard. Selecting ...

AMES, Iowa – An Iowa State University agronomist has helped uncover the genetic mechanisms in sorghum plants that allow hybrids to perform better than parent varieties, a process known as heterosis.
