To develop a successful new grape, these scientists carefully select parent grape plants, cross (also known as "hybridize") them, then apply embryo rescue tactics (see box at right) to produce healthy seedlings.
Ramming pioneered use of embryo rescue several decades ago to breed superb seedless grapes.
Not only that, he advocates the perennialization of existing annuals by embryo rescue
which he describes in the following way.

But Miller saved time using embryo rescue
, a technique that skips such processes by regenerating whole plants from cultures of embryonic tissue.
pinnatisectum--with a derivative of a commercial potato variety, using a technique known as embryo rescue
The researchers had one more roll of the dice: embryo rescue.
Of the 126 remaining lines, 76 pulled through, thanks to the embryo rescue - despite many having been stored more than 19 years.
Embryo culture, says Ramming, is sometimes called embryo rescue
because researchers recover tiny embryos that likely wouldn't survive in nature.
But a viable cross between the two species can involve time-consuming and expensive techniques such as embryo rescue
, says ARS cytogeneticist Bryan K.
