This book, now in its second edition, provides researchers and
operators a complete description of all aspects regarding the wild
ancestor of sugar beet. The possibility of crossing modern crops
with the ancestors from which they are derived in order to recover
some traits lost through domestication is increasingly attracting
interest. The selective process implemented by the first growers
led to the elimination of features not considered useful at the
time. Yet some of these lost traits have now become very important.
In fact, in many areas sugar beet cultivation would now be
impossible without the transfer of some genetic resistances from
Beta maritima, the crop's ancestor. Moreover, the isolation of such
traits is becoming increasingly critical with regard to current and
future environmental and economic considerations on e.g. the use of
pesticides. This second edition replaces certain photographs and
has been updated to reflect the latest advances and findings. One
chapter and several sections have been rewritten, and significant
revisions have been made throughout the text. The new techniques
provide breeders with massively improved analytical means for the
safest and fastest selection procedures. Not only will these
techniques allow Beta maritima to take on a far greater role as a
source of favorable traits; the relative ease with which these
characteristics can be transferred will also make it possible to
use the germplasm of the whole genus Beta and Patellifolia, which
to date has been highly complex, if not impossible, due to the
difficulties of hybridization.

Along the undisturbed shores, especially of the Mediterranean Sea
and the European North Atlantic Ocean, is a quite widespread plant
called Beta maritima by botanists, or more commonly sea beet.
Nothing, for the inexperienced observer's eye, distinguishes it
from surrounding wild vegetation. Despite its inconspicuous and
nearly invisible flowers, the plant has had and will have
invaluable economic and scientific importance. Indeed, according to
Linne, it is considered "the progenitor of the beet crops possibly
born from Beta maritima in some foreign country". Recent molecular
research confirmed this lineage. Selection applied after
domestication has created many cultivated types with different
destinations. The wild plant always has been harvested and used
both for food and as a medicinal herb. Sea beet crosses easily with
the cultivated types. This facilitates the transmission of genetic
traits lost during domestication, which selection processes aimed
only at features immediately useful to farmers and consumers may
have depleted. Indeed, as with several crop wild relatives, Beta
maritima has been successfully used to improve cultivated beet's
genetic resistances against many diseases and pests. In fact, sugar
beet cultivation currently would be impossible in many countries
without the recovery of traits preserved in the wild germplasm. Dr.
Enrico Biancardi graduated from Bologna University. From 1977 until
2009, he was involved in sugar beet breeding activity by the
Istituto Sperimentale per le Colture Industriali (ISCI) formerly
Stazione Sperimentale di Bieticoltura (Rovigo, Italy), where he
released rhizomania and cercospora resistant germplasm and
collected seeds of Mediterranean sea beet populations as a genetic
resource for breeding and ex situ conservation. Retired since 2009,
he still collaborates with several working breeders, in particular,
at the USDA Agricultural Research Stations, at the Chinese Academy
of Agricultural Science (CAAS), and at the Athens University (AUA).
He has edited books, books chapters and authored more than 150
papers. Dr. Lee Panella is a plant breeder and geneticist with the
USDA-ARS at Fort Collins, Colorado. He earned his B.S. in Crop and
Soil Science from Michigan State University, an M.S. in Plant
Breeding from Texas A&M University, and a Ph.D. in genetics
from the University of California at Davis. His research focus is
developing disease resistant germplasm using sugar beet wild
relatives. He is chairman of the USDA-ARS Sugar Beet Crop Germplasm
Committee and has collected and worked extensively with sea beet.
Dr. Robert T. Lewellen was raised on a ranch in Eastern Oregon and
obtained a B.S. in Crop Science from Oregon State University
followed by a Ph.D. from Montana State University in Genetics. From
1966 to 2008 he was a research geneticist for the USDA-ARS at
Salinas, California, where he studied the genetics of sugar beet
and as a plant breeder, often used sea beet as a genetic source to
produce many pest and disease resistant sugar beet germplasm and
parental lines, while authoring more than 100 publications.
