SummaryA hypothetical scheme is given for the evolution of the different types of cauliflower (Brassica oleracea var. botrytis L.). This has been useful in identifying sources of reduced susceptibility to cabbage root fly (Delia radicum (L.)), and may also be useful in the search for reduced susceptibility to clubroot (Plasmodiophora brassicae Woron.). It is argued that knowledge of the phylogeny of types within each crop species is of great importance in the exploitation of genetic resources. 
The exploitation of genetic resources of Brassica oleracea in breeding for resistance to clubroot (Plasmodiophora brassicae)
Most other accessions were highly susceptible but lower levels of susceptibility were observed in open pollinated Brussels sprouts and forms of south European cabbage, cauliflower and broccoli.
Genetic Transformation of Cauliflower (Brassica oleracea var.botrytis) using Agrobacterium Tumefaciens as a Vector for Improved Stress Resistance
A procedure for detection of the presence of insert DNA in recombinant plasmids in individual Agrobacterium tumefaciens strain was refined and the gene cassette was optimize by using PCR.
Evolution of cauliflower types grown in Great Britain as indicated by the isoenzyme composition of the cauliflower curds
The enzymes examined showed evolutionary divergence of the cauliflower types during the selection for different times of development as well as different numbers of isoenzymes depending upon which of the three main groups of cauliflower cultivars were used.
Breeding Cauliflower: A Review
The rapidly growing knowledge of advance tools of parental line development, molecular markers, and biotechnological techniques will provide enhanced precision and extend options to support future cauliflower breeding programs.
The distribution of BoCAL-a alleles in Brassica oleracea is consistent with a genetic model for curd development and domestication of the cauliflower
A genetic model based on segregation of recessive alleles at specific, mapped loci of the candidate genes BoCAL and BoAP1 suggests that the cauliflower curd arose in southern Italy from a heading Calabrese broccoli via an intermediate Sicilian crop type.
Using molecular allelic variation to understand domestication processes and conserve diversity in Brassica crops
An example of how variation at a small number of loci requires careful interpretation in the context of crop domestication is outlined, and the results indicate that it is important to consider the effect of strong selection for crop type on genetic erosion of loco linked in coupling to genes underlying the crop phenotype.
Diversity of Sicilian broccoli (Brassica oleracea var. italica) and cauliflower (Brassica oleracea var. botrytis) landraces and their distinctive bio-morphological, antioxidant, and genetic traits
This work characterized a set of broccoli and cauliflower landraces and F1 hybrids, traditionally grown in Sicily, an important evolution center for both crops, on the basis of biochemical and biomorphological parameters to offer new parameters to delineate discriminant traits between the two crops.
Evaluation of French Brassica oleracea landraces for resistance to Plasmodiophora brassicae
Two lines selected from a resistant kale population were highly resistant against a large range of pathotypes of the pathogen and presented a sufficient level of resistance to be directly useful in the breeding program in order to develop cauliflower and broccoli hybrids resistant to clubroot.
A Review of Hybrid Cauliflower Development
In cauliflower, F1 hybrids have been found advantageous for earliness, high early and total yield, better curd quality with respect to compactness and color, uniform maturity, resistance to insect pest, diseases and unfavorable weather conditions.
The origins of edible brassicas
The evolution in cultivation of the two species, Brassica oleracea and B. rapa, which in parallel developed similar forms of edible plants are examined.


Breeding system, taxonomy, and breeding strategy in cauliflower, Brassica oleracea var. botrytis L.)
It is argued that despite demonstrable heterosis within many groups of cauliflowers, radical advances are probably best made by selecting self-compatible material from annual × biennial hybrid populations.
Gene pools in Phaseolus and Vigna cultigens
SummaryThe nature and extent of the gene pools in cultigens of the genera Phaseolus and Vigna, as indicated by studies of experimental interspecific hybridization, are reviewed. In all cases a
A mutation affecting curd colour in cauliflower (Brassica oleracea L. var. Botrytis DC)
SummaryA single gene mutation in cauliflower resulted in the production of an orange coloured curd when heterozygous, and a stunted orange curd when homozygous. The orange heterozygote has commercial
The use of aseptic meristem culture in cauliflower breeding
SummaryThe upper surface of the cauliflower curd consists of a mass of apical meristems. These would normally develop into flowers, but if devernalised they revert to the vegetative phase and develop
Genotypic and environmental effects on curd weight of autumn-maturing cauliflowers
There was a high genotypes component of variation for curd weight, indicating that this character can be improved by breeding, and a large genotype × environment interaction included genotypic differences in stability to the environment, notably in the self-compatible genotypes.
