The Impact

Small plot trials studying the impact of different seed treatments on the occurrence of pests and diseases in autumn were carried out during 2000–2003. The aim was to verify the efficiency of different fungicidal and insecticidal oilseed rape seed treatments and to determine the economical effectiveness of this method of protection. The following insecticidal seed treatments were used: Promet 400 CS (furathiocarb), Cosmos 500 FS (fipronil), Chinook 200 FS (imidacloprid & beta-cyfluthrin) and Marshal ST (carbosulfan). The seed treatment Chinook 200 FS in combination with newly developed fungicidal compound was also assessed. The most effective treatment was Chinook 200 FS (imidacloprid & beta-cyfluthrin), particularly against flea beetles (Phyllotreta spp.), and lower infestations by larvae of the turnip gall weevil (Ceutorhynchus pleurostigma Marsh.) were also found. However, the efficiency lasts no more than 4–5 weeks after sowing. The use of common insecticidal treatments in cases of necessity was found to be beneficial. Plant density in autumn and in spring was greatest in the Chinook 200 FS treatment and in some years a positive influence on yield was also observed with this treatment.

Flowering Locus

Abstract Key message A novel structural variant was discovered in the FLOWERING LOCUS T orthologue BnaFT.A02 by long-read sequencing. Nested association mapping in an elite winter oilseed rape population revealed that this 288 bp deletion associates with early flowering, putatively by modification of binding-sites for important flowering regulation genes. Abstract Perfect timing of flowering is crucial for optimal pollination and high seed yield. Extensive previous studies of flowering behavior in Brassica napus (canola, rapeseed) identified mutations in key flowering regulators which differentiate winter, semi-winter and spring ecotypes. However, because these are generally fixed in locally adapted genotypes, they have only limited relevance for fine adjustment of flowering time in elite cultivar gene pools. In crosses between ecotypes, the ecotype-specific major-effect mutations mask minor-effect loci of interest for breeding. Here, we investigated flowering time in a multiparental mapping population derived from seven elite winter oilseed rape cultivars which are fixed for major-effect mutations separating winter-type rapeseed from other ecotypes. Association mapping revealed eight genomic regions on chromosomes A02, C02 and C03 associating with fine modulation of flowering time. Long-read genomic resequencing of the seven parental lines identified seven structural variants coinciding with candidate genes for flowering time within chromosome regions associated with flowering time. Segregation patterns for these variants in the elite multiparental population and a diversity set of winter types using locus-specific assays revealed significant associations with flowering time for three deletions on chromosome A02. One of these was a previously undescribed 288 bp deletion within the second intron of FLOWERING LOCUS T on chromosome A02, emphasizing the advantage of long-read sequencing for detection of structural variants in this size range. Detailed analysis revealed the impact of this specific deletion on flowering-time modulation under extreme environments and varying day lengths in elite, winter-type oilseed rape.
