Summary: The study showed that using modified conventional polyurethane coated CAN fertilizer in a single application during the growth stage of the 9th true leaf significantly increased yield, thousand seed weight, and oil production for Brassica napus L. The coated CAN fertilizer has the potential to achieve slow nitrogen release, ensuring nitrogen supply for rapeseed plants throughout the vegetation period and eliminating the risk of nitrogen loss.

Summary: In this study, differential expression of total protein in leaves of two transgenic oilseed rape lines and their non-transgenic parent plant was analyzed. Fourteen differential protein spots were identified, including eleven upregulated and three downregulated proteins, involved in photosynthesis, transporter function, metabolism, protein synthesis, and cell growth and differentiation. These changes in protein spots may be attributed to the insertion of foreign transgenes in transgenic oilseed rape, but transgenic manipulation does not necessarily cause significant changes in the proteomes of oilseed rape.

Summary: Accurate and timely knowledge of crop phenology is crucial for planning farming activities. The PolSAR technique has potential for crop phenology retrieval due to its short revisit time, all-weather monitoring, and sensitivity to vegetation structure. In this study, averaged Stokes-related parameters derived from multiple PolSAR data were explored for oilseed rape phenology identification, showing high sensitivity to oilseed rape growth stages.

Summary: Branch architecture is a vital factor affecting rapeseed planting, and this study identifies related genes and regulatory mechanisms through evaluating and analyzing branch angle and branch dispersion degree. Significant loci and candidate genes are identified, providing a theoretical basis for further research on gene cloning and genetic improvement of branch architecture.

Summary: The study found that at low boron supply, plants fed with nitrate and ammonium had similar B-10 uptake rates, accumulation, and xylem B-10 concentrations, but these attributes were reduced at high boron supply. Ammonium-induced acidity and nitrate-induced alkalinization led to altered B distribution between roots and shoots as well as different B transport mechanisms in plants.

Summary: This study conducted a manipulative experiment on Brassica napus var. oleracea to monitor the dynamics of δN-15 in purified DNA, source leaf, and root materials over a 60-day growth period. The results showed that the δN-15 dynamics of leaves and roots depend on the labeled chemical species, with some unexpected findings regarding isotopic fractionation and N-15 depletion in plant DNA. While the study did not assess the fractionation coefficient (epsilon) associated with DNA bases biosynthesis, it provides valuable insights into the dynamics of specific plant molecular pools over a long observation period using heavy labelling techniques.

Summary: This study investigated the effects of genotype, environment, and their interaction on seed yield and breeding traits of winter oilseed rape. The results showed significant differences in yield and other traits among the tested genotypes across different years and locations. The correlation analysis indicated a strong negative relationship between seed yield and the beginning of flowering. Multivariate statistical methods were used to characterize the tested genotypes in terms of multiple traits, revealing variations between different cultivars and lines.

Summary: Reutilization of waste sulfur can be an interesting option to supply sulfur to the soil. The mixture of sulfur with ammonium sulfate and ammonium nitrate is a more optimal alternative, which can improve nitrogen use efficiency and reduce the reliance on mineral fertilizers.

Summary: This study discussed the main reason for high oilseed rape loss in mechanized harvesting and proposed a 2-degree-of-freedom collision method (2-DFCM) for selecting varieties with high resistance. The results showed that 2-DFCM is more reliable, convenient for field testing, and accurately identifies pod characteristics, which is important for breeding oilseed rape varieties.

Summary: This study improves the threshing concave plate of oilseed rape harvesters to enhance the performance and efficiency of oilseed rape separation. The optimal combination of parameters for the threshing device is determined through simulation analysis and field testing. The results demonstrate that the concave plate with a 360 degrees wrap angle has better performance and operational efficiency.

Summary: Limited genetic variability is a major issue in rapeseed breeding, with strict selection and domestication leading to reduced diversity. This study assessed variability in DH lines and hybrids, finding significant differences in traits. Results showed that there was no significant correlation between hybrid heterosis and parental line distances.

Summary: Climate change has significant impacts on canola seed yield and quality. The timing and duration of heat and drought stresses greatly affect canola production. Short-term heat stress before the end of flowering has the largest impact on seed yield, while long-term drought during flowering or short-term drought during pod setting has the greatest yield impact.
