Identification of traits for nitrogen use efficiency in oilseed rape (Brassica Napus L.)Miro, Berta January 2010 (has links)
Oilseed rape (Brassica napus L.) receives high inputs of Nitrogen (N) fertiliser while N uptake and N harvest index are low. This results in high residual soil N which leaches to water bodies and contributes to greenhouse emissions. Such negative environmental impact could be reduced by better understanding the genetic basis of N metabolism in oilseed rape and designating relevant traits for varietal selection towards high nitrogen use efficiency (NUE) at low N fertiliser inputs. In this study the doubled haploid population (TNDH) from a cross between the Chinese semi-winter variety Ningyou7 and the UK winter variety Tapidor was analysed for N physiology and Quantitative Trait Locus (QTL) mapped for relevant traits. Quantitative Trait Loci were mapped in two N treatments over two consecutive field trials for architectural traits such as plant height, foot length, pod number and chlorophyll content in bracts and leaves; yield and yield component traits such as plant biomass, seed yield, harvest index and N metabolism (seed, plant and total N concentration, N uptake, utilisation and use efficiencies and N harvest index). A larger number of QTL were detected at High N than at Low N. In total 49 QTL were detected at High N versus 44 in Low N during 2005/06, while in 2007/07, 72 versus 62 QTL were detected at High and Low N respectively. Most QTL for different traits were treatment specific. Novel QTL for agronomic traits specific at Low N were identified. The correlations between traits were also studied through QTL co-localisations, particularly for relationships between seed yield, N uptake and N use efficiency. Seven chromosomal regions are discussed for potential candidate genes. Additionally, QTL reproducibility, interval mapping and composite interval mapping, QTL x environment interactions and phenotypic plasticity in oilseed rape are also discussed.
