Effects of Picking Flowering Stalk on Agronomic Traits and Economic Benefits of Brassica napus L.
In order to improve the application value of Brassica napus, the multifunctional utilization of Brassica napus was explored. In this experiment, we selected Brassica napus G1 with excellent agronomic characters as the male parent and G2 as the female parent to construct 289 double haploid (DH) pure lines. We investigated and evaluated the flowering stalk yield, plant characters, seed yield, biological yield and economic benefits of the lines. And then we screened “rapeseed oil-vegetable dual-purpose” Brassica napus lines with high flowering stalk yield, no impact on Brassica napus seed yield and high economic benefits. The results showed that the branch height (BH) and the first branch number (NFB) were negatively correlated with Brassica napusseed yield. Compared with the control, picking flowering stalk reduced plant height (PH), BH and NFB, and the difference reached a significant level; in DH population, there was a negative correlation between Brassica napus seed yield and flowering stalk yield. After picking flowering stalk, the Brassica napus seed yield decreased by 19.24% on average compared with that without picking, but the total output value increased by 48.87% on average. Among the materials, the Brassica napus seed yield of 48 selected materials (with a yield variation range of -10%-10%) was not affected by picking flowering stalk, while that of 63 selected materials increased by more than 10% after picking. Brassica napus seed yield of 30 materials exceeded 3000 kg/hm2. Based on the above indicators, 21 “rapeseed oil-vegetable dual-purpose” materials with good yield and economic benefit were selected in this experiment, whose yield of flowering stalk and rapeseed both met the yield requirements of the Brassica napus seed region in the Yangtze River basin. The study can provide theoretical guidance and scientific basis for the breeding and promotion of dual-purpose rapeseed.

Among the Brassica oilseeds, canola (Brassica napus) is the most economically significant globally. However, its production can be limited by blackleg disease, caused by the fungal pathogen Lepstosphaeria maculans. The deployment of resistance genes has been implemented as one of the key strategies to manage the disease. Genetic resistance against blackleg comes in two forms: qualitative resistance, controlled by a single, major resistance gene (R gene), and quantitative resistance (QR), controlled by numerous, small effect loci. R-gene-mediated blackleg resistance has been extensively studied, wherein several genomic regions harbouring R genes against L. maculans have been identified and three of these genes were cloned. These studies advance our understanding of the mechanism of R gene and pathogen avirulence (Avr) gene interaction. Notably, these studies revealed a more complex interaction than originally thought. Advances in genomics help unravel these complexities, providing insights into the genes and genetic factors towards improving blackleg resistance. Here, we aim to discuss the existing R-gene-mediated resistance, make a summary of candidate R genes against the disease, and emphasise the role of players involved in the pathogenicity and resistance. The comprehensive result will allow breeders to improve resistance to L. maculans, thereby increasing yield.
