Among the cole crops, cauliflower (Brassica oleracea L. var. botrytis L. subvar. cauliflora DC.) follows cabbage in importance with regard to area and production in the world. However, in India cauliflower is more widely grown than cabbage. This crop grows at latitudes 110 N to 60? N with average temperature ranging from 5?-8?C to 25 ?-28 0C. In its vegetative growth period it may stand temperatures as low as -100C and as high as 40?C for a few days. The total area under cauliflower in the… 
Genetic improvement of cauliflower
In cauliflower, F1 hybrids have been found been found bred 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.
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.
Polygenic Variations and Character Association in Early Maturing Indian Cauliflowers (Brassica oleracea var. botrytis L.)
Cauliflower is one of the important vegetable crops, grown throughout the year in different agroclimatic zones and is mainly grown for its curds which are rich in vitamin-C (ascorbic acid) and also the minerals like phosphorus, potassium, calcium, sodium and iron.
Frequent introgression of European cauliflowers in the present day cultivated Indian cauliflowers and role of Indian genotypes in the evolution of tropical cauliflower
The frequent introgression of snowball types in the evolution of Indian cauliflowers with requirement of comparatively lower temperature is established and the role of the Indian cauliflower genotypes with high temperature tolerance in the Evolution of present day tropical caulifLowers is established.
Screening of cauliflower (Brassica oleracea L. var. botrytis L.) germplasm for resistance to downy mildew [Hyaloperonospora parasitica Constant (Pers.:Fr) Fr.] and designing appropriate multiple resistance breeding strategies
Different stages of plant development showed a strong positive correlation for downy mildew reaction in the genotypes tested, and genotypes identified as resistant can be used as donors to develop multiply-resistant varieties of cauliflower.
Genetic Diversity Assessment for Growth and Yield Traits in Cauliflower
The phenotypic coefficient of variation were observed to be higher than the corresponding genotypic coefficients of variation for all the characters studied, however the differences was narrow which implied their relative resistance to environmental variation.
Agro-morphological and molecular diversity in different maturity groups of Indian cauliflower (Brassica oleracea var. botrytis L.)
The present study indicates for introgression of genetic fragments across the maturity groups, thereby, potential for use in further genetic improvement and heterosis breeding.
Genetic Characterization of Self-incompatible Lines and Strategies for Heterosis Breeding in Cauliflower
To identify diverse parental lines for breeding in early and mid-maturity Indian cauliflower, genetic characterization of self-incompatible inbred lines was carried out based on quantitative and molecular analyses and moderate diversity at the molecular level could be utilized for heterosis breeding.
Exploiting double haploidy in cauliflower (Brassica oleracea var. botrytis L.) for crop improvement
A study was conducted to augment a viable protocol for the development of double haploid system in cauliflower, using in-house genotypes, by anther culture. A total of 13,680 anthers were cultured on


Novas linhagens de repôlho e couve-flor para o Estado de São Paulo
Investigations on the cabbage and cauliflower at the Instituto Agronomico and its various experiment stations were intensified since 1941, and types that were capable of making satisfactory growth and forming heads during those months of the year when temperature was high were turned to.
Investigations into the breeding system of cauliflower Brassica oleracea var. botrytis (L.)
Calculations of the percentage of hybrid seeds in each quarter of thesiliqua showed that the ratio of hybrid: self seeds was the same in all quarters of the siliqua, indicating that restrictions of pollen tube growth in these cauliflower types is confined to the stigmatic surface.
Investigations into the breeding system of cauliflower
In experiments to study the effect of inbreeding, I1 progenies of summer cauliflower showed a trend towards increase in plant weight over their non-inbred commercial parents. Curd quality, however,
Pollination and contamination of Brassica oleracea L
Trials of cauliflower have shown that a high degree of selfing naturally occurs in this crop, and a number of factors influencing interpollination are discussed.
[Contributions to the analysis of the Brassica-genome].
The results agree with earlier observations and confirm the presence of balanced secondary polyploidy in Brassica derivable from a basic chromosome number x=6.
Beiträge zur Analyse des Brassica-Genoms
These results agree with earlier observations and confirm the presence of balanced secondary polyploidy in Brassica derivable from a basic chromosome number x=6 and prove partial homology in the different genomes of some chromosomes belonging to the same structural type.
Hybrid breeding in early spring cabbage
A new selection method is described which can supply the same information as the method of diallel crosses, both in inter- and intravarietal crosses and on the breeding of hybrid varieties of pointed-headed cabbage.
Gene Effects and Heterosis in Cauliflower—II
Studies on the inheritance of leaf number, leaf size index, plot yield and number of marketable curds, indicated that dominance and epistasis, especially dominance x dominance, had a major role.
