Breeding histories and selection criteria for oilseed rape in Europe and China identified by genome wide pedigree dissection
Abstract Selection breeding has played a key role in the improvement of seed yield and quality in oilseed rape (Brassica napus L.). We genotyped Tapidor (European), Ningyou7 (Chinese) and their progenitors with the Brassica 60 K Illumina Infinium SNP array and mapped a total of 29,347 SNP markers on...
