Book Description
Excerpt from Cultural Studies on Carrot Stecklings in Relation to Seed Production Stock seed of Red Core Chantenay carrot was sown in a series of experiments from 1945 to 1949 at Logan, Utah, to determine the effect Of rate of seeding, time Of planting, and width of planting shoe on the numbers and distribution by Size of the stecklings produced. Many Of the same stecklings were later used in other experiments to determine the effect of steckling size on stand, rate of plant develop ment, height, branching habit, seed yield, and viability. A time-of harvest treatment was also combined-with some of the studies. From these experiments, the following conclusions have been drawn. Within practical limits, it is almost impossible to produce in an nu thinned seedbed a crop of carrot stecklings of uniform size. Although the proportion Of medium-size roots may remain relatively stable within a series Of treatments, greater numbers Of larger roots are Obtained only at the expense Of producing fewer smaller ones. The reverse is also true. The largest numbers of suitable stecklings were Obtained by sowing at about 14 pounds per acre in rows a foot apart in early to mid-june. Plantings as late as July 29 prevented the development of many large stecklings, but plantings as early as June 4 did not prevent the appearance of some small stecklings at harvesttime.

Book Description
Excerpt from Synonymy of Orange-Fleshed Varieties of Carrots Much of the material for this circular was compiled from large scale carrot-variety tests conducted at the Cheyenne Horticultural Field Station, Cheyenne, Wyo., from 1932 to 1946. Varieties for these tests were collected from all countries where commercial carrot-seed production is an important industry and consequently where new varieties originate and old ones continue to be propagated. An effort has been made to obtain all types and varieties listed in commercial trade channels. So far as known, not over a half-dozen well-known or standard varieties were omitted from the tests; practically all of those omitted are varieties grown in northern Europe and not widely known elsewhere. Their principal characteristics and most probable synonymy as obtained from printed descriptions and illustrations are given; the interpretations were checked by authorities on European carrot varieties. This circular is designed to be used as a handbook, and all varieties, strains, and synonyms are list-cd in alphabetical-order in an index, which gives the groups and the figure numbers as well as the page numbers. In each standard subgroup and in each group in which there are no subgroups the type variety is described first and then the strains and synonyms are discussed in alphabetical order. In the other subgroups the. Alphabetical order is followed. In the synopsis the lists are alphabetical under each group or subgroup.

Book Description
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 Linnè, 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.

Book Description
How can cultivated plant biodiversity contribute to the transformation and the "ecologization" of agriculture in Southern countries? Based on extensive field work in the Southern countries, a great deal of scientific progress is presented in all areas affecting agriculture (agronomy, plant breeding and crop protection, cultivation systems, etc.) in order to intensify the ecological processes in cultivated plots and at the scale of rural landscapes.
