Modelling seedbank dynamics of volunteer oilseed rape (Brassica napus )

Agricultural Systems, 2004
A simple mechanistic model is presented which describes population dynamics of volunteer oilseed rape within a field. The model calculates the number of volunteers appearing in each crop and the seedbank after each crop.

Progressive introgression between ¤Brassica napus¤ (oilseed rape) and ¤B-rapa¤ [PDF]

Heredity, 2003
Udgivelsesdato: 2003-SepWe have earlier shown extensive introgression between oilseed rape (Brassica napus) and B. rapa in a weedy population using AFLP markers specific for the nuclear genomes. In order to describe the progress of this introgression, we

Inheritance of oilseed rape (Brassica napus) RAPD markers in a backcross progeny with Brassica campestris

TAG Theoretical and Applied Genetics, 1996
Different cultivars/transgenic lines of oilseed rape (Brassica napus) were crossed (as females) with different cultivars/populations of Brassica campestris.

Frequent nonreciprocal translocations in the amphidiploid genome of oilseed rape (Brassica napus)

Genome, 1995
A RFLP map of Brassica napus, consisting of 277 loci arranged in 19 linkage groups, was produced from genetic segregation in a combined population of 174 doubled-haploid microspore-derived lines. The integration of this map with a B.

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus). [PDF]

Pest Manag Sci
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.). [PDF]

Pest Manag Sci
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

The effect of pollination on the growth and reproduction of oilseed rape (Brassica napus)

Basic and Applied Ecology, 2022
Phenotypic plasticity is an organism's ability to alter its development and life history in response to environmental conditions. In plants, biotic and abiotic factors drive the distribution of resources between growth and reproductive traits. One such biotic factor is pollination.

Hormones and Pod Development in Oilseed Rape (Brassica napus) [PDF]

Plant Physiology, 1989
The endogenous levels of several plant growth substances (indole acetic acid, IAA; abscisic acid, ABA; zeatin, Z; zeatin riboside, [9R]Z; isopentenyladenine, iP; and isopentenyladenosine, [9R]iP were measured during pod development of field grown oilseed Rape (Brassica napus L.

First report of Leptosphaeria sclerotioides on Brassica napus in Northwestern China

Oil Crop Science, 2023
In 2020, diseased seedlings of winter oilseed rape (Brassica napus) with cankered taproots as well as abundant sclerotium-like structures in the soil surrounding the roots were found in Longxi County of Gansu province of northwestern China. A fungus with

Genetic dissection of branch architecture in oilseed rape (Brassica napus L.) germplasm. [PDF]

Front Plant Sci, 2022
Branch architecture is an important factor influencing rapeseed planting density, mechanized harvest, and yield. However, its related genes and regulatory mechanisms remain largely unknown. In this study, branch angle (BA) and branch dispersion degree (BD) were used to evaluate branch architecture.
