Identification and Chromosomal Assignment of RAPD Markers Linked with a Gene for Seed Colour in a Brassica Campestris‐Alboglabra Addition Line
TL;DR: Random amplified polymorphic DNA marker analysis revealed 19 markers specific to the alien C-genome chromosome of the addition line of the added line which harbours a B. alboglabra chromosome with a gene controlling seed colour.

Satellited Chromosomes, Nucleolus Organizer Regions and Nucleoli of Brassica campestris L., B. nigra(L.) Koch, and Sinapis arvensis L.
B.F. Cheng,Waheeb K. Heneen +1 more
TL;DR: The presence of three pairs of active NORs in B. nigra and S. arvensis is an additional support for the hypothesis of a basic number of ×= 3 in the Brassiceae, and silver staining was used to characterize the satellited chromosomes.

Ribosomal RNA Gene Loci and Their Nucleolar Activity in Brassica alboglabra Bailey
TL;DR: It is suggested that the satellited chromosome pair 9 with Ag-NORs contains major active rRNA gene loci leading to the formation of major nucleoli, while the non-satellite chromosome pair 8 without detectable Ag- NORs carries minor active rRNAs responsible for the formation for micronucleoli.

Cytogenetic studies on Brassica campestris primary trisomics
TL;DR: The segregation of erucic acid content in the F2 progenies of the selfed trisomic F1 plants from the two crosses showed a disomic inheritance pattern, thus indicating that the trisomy in No.2891 and No. 2881 did not involve the chromosome carrying the erucing acid gene.

Characterization of the A and C Genomes of Brassica Campestrisand B. Alboglabra
TL;DR: The combination of different marker systems and cytological techniques for the characterization of the A and C genomes and their constituent chromosomes has obvious implications for plant breeding, assessment of gene introgression in nature, and evolutionary studies.
