The breeding companies and laboratories involved in this article cover a wide range of crops grown in the temperate climate zone: small grain cereals, oilseed crops, forage crops, turf, vegetables and potato. Speed and efficiency are becoming increasingly important in variety breeding and doubled haploids (DH) and genetic markers are important(More)
Genetic diversity was studied in a collection of 61 accessions of Brassica rapa, which were mostly oil-type turnip rapes but also included two oil-type subsp. dichotoma and five subsp. trilocularis accessions, as well as three leaf-type subspecies (subsp. japonica, pekinensis, and chinensis) and five turnip cultivars (subsp. rapa). Two-hundred and nine SNP(More)
A rye doubled haploid (DH) mapping population (Amilo × Voima) segregating for pre-harvest sprouting (PHS) was generated through anther culture of F1 plants. A linkage map was constructed using DHs, to our knowledge, for the first time in rye. The map was composed of 289 loci: amplified fragment length polymorphism (AFLP), microsatellite, random amplified(More)
To prevent lodging and sprouting damage in rye, a dominant dwarfing gene, Ddw1, has been incorporated into breeding lines to reduce plant height in Finland. However, the inability to identify heterozygous plants makes it difficult to purify breeding lines. Doubled haploidy (EM-1 × Voima) and bulked segregant analysis were used to search for an efficient(More)
Rye is generally a recalcitrant species in anther culture, although relatively high green plant regeneration rates have been reported for some cultivars. Pre- and post-plating stress treatments and media that in previous experiments have given promising results were tested in combinations to improve green plant regeneration from anther culture for a wide(More)
