The functional significance for anthocyanin accumulation has not yet been conclusively clarified, but it seems likely that anthocyanins act as light attenuators to control an efficient chlorophyll breakdown and thus enable a better nutrient retrieval of senescing leaves (Koeslin‐Findeklee et al., ).…”

Oilseed rape suffers from serious waterlogging in many regions of the world limiting the cultivation area for rapeseed. Due to the man‐induced climate change, the risk of severe waterlogging events and associated therewith the damage of rapeseed plants will increase, even in Europe and North America. To investigate the effects of waterlogging on growth, yield and seed quality, rapeseed was cultivated throughout its vegetation period and waterlogged for 14 days at two different growth stages: at stem elongation (BBCH 31) or at floral bud appearance (BBCH 55). The experiments revealed that waterlogging at BBCH 31 affected plant growth and nutrient accumulation and finally resulted in lower yields. Waterlogging at BBCH 55 seriously impaired main racemes, but due to an increased production of secondary racemes, yield losses were lower than after waterlogging at BBCH 31. Oil quality was not affected by any waterlogging treatment under the chosen experimental conditions.

“…In contrast, Cab gene expression was found to decrease during senescence (Noh and Amasino 1999). A recent study identified genes showing differential expression under high and low N conditions in rapeseed, revealing that genes related to photosynthesis, photorespiration, and cell-wall structure are repressed under N starvation, whereas genes related to mitochondrial electron transport and flavonoid synthesis show enhanced expression (Koeslin-Findeklee et al 2015b). The previously mentioned superiority of semidwarf hybrids with regard to nitrogen utilization efficiency was associated with two QTLs, on chromosomes A07 and A06, the latter of which is assumed to coincide with the B. napus dwarf mutation bzh (Miersch 2014).…”

Mineral nitrogen fertilization has improved crop yield over the last century but has also caused air and water pollution. Reduction of nitrogen inputs and maintaining high yields are therefore essential to ensure a more sustainable agriculture. Improving the nitrogen use efficiency (NUE) of crops is therefore needed. Rapeseed, Brassica napus, depends on nitrogen fertilization due to its low NUE, with the ratio of plant nitrogen content to nitrogen supplied often not exceeding 60 %. Here, we review the major phenotypic traits associated with NUE in B. napus, with special emphasis on winter oilseed rape. We discuss the genetic diversity available and potential breeding strategies. The major points are the following: (1) rapeseed seed yield elaboration is complex, with overlapping phases of nitrogen uptake and remobilization during the crop cycle; (2) traits related to nitrogen uptake, such as root length and the amount of nitrogen absorbed after flowering, and traits related to nitrogen remobilization, such as the "staygreen" phenotype, have been identified as possible levers to improve NUE in rapeseed; (3) a substantial body of studies investigating the genetic control of NUE traits have already published and potential candidate genes identified; and (4) rapeseed genetic diversity may be enriched by exploiting interpopulation genetic variation and the closely related gene pools of Brassica rapa and Brassica oleracea.
