First identified at CSHL by George Shull in 1908, hybrid vigor - or heterosis, as biologists call it - involves interbreeding genetically distinct plants to generate offspring more robust than either inbred parent.
Our results demonstrate successful hybridization between a Chilean scallop population and a bay scallop population, with considerable hybrid vigor being observed, implying the existence of a more complex genetic basis.
Hybrid plants often are more robust than their parents -- they have so-called ''hybrid vigor.''
When hybrids are stocked, you get a fish with hybrid vigor, technically, heterosis.
In contrast to previous studies, these findings confirm significant genetic diversity in Jatropha which enables SGB breeders to maximize hybrid vigor by identifying the most genetically diverse parental lines to use for the creation of elite hybrid seeds.
"Scientists still don't completely understand how hybrid vigor occurs," Steve says.
For exploiting hybrid vigor, per se performance, sca effects and the extent of heterosis of hybrids are important.
Andrews' unusual combination exhibits hybrid vigor.
The other three hybrids; Red Maradol as female x Sunrise as male, Red Maradol as female x Solo Kapoho as male, and Solo Kapoho as female x Red Maradol as male, did not show hybrid vigor in this evaluation, since there was no significant difference with the control, nor among them.
Red oaks hybridize, too, but don't seem to obtain the famed hybrid vigor as often as white oaks.
