Production of haploids and doubled haploids in oil palm [PDF]

BMC Plant Biology, 2010
Background Oil palm is the world's most productive oil-food crop despite yielding well below its theoretical maximum. This maximum could be approached with the introduction of elite F1 varieties.

Doubled Haploids in Eggplant [PDF]

Biology, 2021
Eggplant is a solanaceous crop cultivated worldwide for its edible fruit. Eggplant breeding programs are mainly aimed to the generation of F1 hybrids by crossing two highly homozygous, pure lines, which are traditionally obtained upon several self ...

Effect of genotypic background on haploid production through embryo rescue in wheat × maize crosses - Short Communication

Plant, Soil and Environment, 2005
Two high yielding wheat (Triticum aestivum L.) varieties were pollinated with seven agrarian superior varieties. F1's thus obtained were pollinated with diverse winter maize lines/composites and treated with a solution containing 2,4-D and GA3.

Stable demographic ratios of haploid gametophyte to diploid sporophyte abundance in macroalgal populations.

PLoS ONE
Macroalgal populations often consist of free-living haploid (gametophyte) and diploid (sporophyte) stages. Various ecological studies have been conducted to examine the demographic diversity of haploid-diploid populations with regard to the dominant ...

USE OF CELL ENGINEERING FOR DEVELOPMENT OF THE CONSTANT INITIAL BREEDING MATERIAL OF WHITE HEAD CABBAGE CV. NADZEJA AND CMS SAMPLES

Овощи России, 2015
The anther derived androgenic plants of white head cabbage cv. Nadzeja and CMS samples were obtained. The cytological analysis of ploidy level of regenerated plants and doubled haploids obtained by treatment of meristems with colchicine was performed. On

Engineered intraspecific hybrid lethality enables rapid haploid isolation and cytoplasm conversion in tobacco

Crop Journal
Haploid plants can improve the efficiency of cultivar development by shortening breeding cycles and increasing genetic gain per unit of time. The ability to produce androgenic haploids from seed can also permit development of approaches for rapid ...

In vivo HAPLOID INDUCTION AND EFFICIENCY OF TWO CHROMOSOME DUPLICATION PROTOCOLS IN TROPICAL MAIZE

Ciência e Agrotecnologia, 2015
Artificial chromosome duplication is one of the most important process in the attainment of doubled haploids in maize. This study aimed to evaluate the induction ability of the inducer line KEMS in a tropical climate and test the efficiency of the R1 ...

Effect of Salt Stress on Mutation and Genetic Architecture for Fitness Components in Saccharomyces cerevisiae

G3: Genes, Genomes, Genetics, 2020
Mutations shape genetic architecture and thus influence the evolvability, adaptation and diversification of populations. Mutations may have different and even opposite effects on separate fitness components, and their rate of origin, distribution of ...

Intracallus cytotypic variation of regenerated Oryza sativa L. plants in the in vitro androgenesis

Труды по прикладной ботанике, генетике и селекции
Background. The in vitro androgenesis has proven to be a reliable method for obtaining doubled haploids for many plant species. In the breeding of Oryza sativa L., in vitro culture of anthers is used, which go through the stage of callus formation ...
