Potential use of RAPD markers in characteristics of cucumber (Cucumis sativus L.) haploids and double-haploids

Acta Societatis Botanicorum Poloniae, 2011
A study was designed to obtain hapolid and double haploid (DH) plants from cucumber cultivars tolerant to Pseudoperonospora cubensis. The main goal was to identify RAPD molecular markers associated with downy mildew resistance. On average, 20% of embryos

Functional analysis of the dehydratase domains of the PUFA synthase from Emiliania huxleyi in Escherichia coli and Arabidopsis thaliana

Biotechnology for Biofuels and Bioproducts, 2022
Background Polyunsaturated fatty acid (PUFA) synthase is a multi-domain mega-enzyme that effectively synthesizes a series of PUFAs in marine microorganisms. The dehydratase (DH) domain of a PUFA synthase plays a crucial role in double bond positioning in

Factors affecting DH plants in vitro production from microspores of European radish.

Vavilovskii zhurnal genetiki i selektsii, 2020
Over the recent years the market demand for scaling up the production of European radish (Raphanus sativus L.) varieties and hybrids for open and protected production, varying in ripeness group, root shape and color, has drastically increased. Therefore, the expansion of genetic diversity and acceleration of the selection process are important. Doubled

Efficiency of Microspore Culture for Doubled Haploid Production in the Breeding Project "Czech Winter Rape"

Czech Journal of Genetics and Plant Breeding, 2006
A selected set of twenty inter-line F1 hybrids of Brassica napus L. was evaluated for their capacity to produce microspore-derived doubled haploid (DH) plants subsequently utilized in the breeding project "Czech Winter Rape".

Diploidization of cucumber (Cucumis sativus L.) haploids by colchicine treatment

Acta Societatis Botanicorum Poloniae, 2014
Haploid cucumber plants are totally infertile and do not undergo spontaneous diploidization. The use of haploids depends on the possibility of doubling the chromosome number and the obtaining of stable doubled haploids (DH).

FEATURES OF SEED FORMATION IN DOUBLE HAPLOID LINES OF BROCCOLI IN DIFFERENT GENERATIONS

Овощи России, 2017
The biotechnological methods enable to produce the ‘pure’ lines for the short period of time that intensify the breeding program. Particularly, the anther culture is widely used to obtain double haploid lines (DH lines) in plant breeding.
