Inheritance of seed quality and seed germination in two doubled haploid populations of oilseed rape segregating for acid detergent lignin (ADL) content

Abstract The high lignin content of the seed hull oilseed rape leads to its black color compared yellow seeded soybean. Reducing and increasing oil protein is an important breeding aim in rape. objective present study was analyze inheritance two rapeseed genetic resources with reduced seeds elucidate effects on germination composition. These were crossed Express 617 F1 plants used develop doubled haploid (DH) populations. DH populations tested field experiments three five environments. Significant variation for bimodal frequency distributions found both SNP marker segregation contrasting bulks revealed overlapping narrow genomic regions chromosome C03, responsible content. low had a significantly higher percentage showing bacterial fungal growth, but vigor not affected. Non-targeted metabolome analysis immature green showed exclusively depletion metabolites proanthocyanidin pathway lines In these lines, cinnamate-4-hydroxylase gene copy identified as candidate region newly QTL C03 valuable studying additive epistatic combination other genotypes.
