Multi-environment trials are routinely conducted in plant breeding to select candidates for the next selection cycle. In this study, we compare prediction accuracy of four developed genomic-enabled models: (1) single-environment, main genotypic effect model (SM); (2) multi-environment, effects (MM); (3) single variance G×E deviation (MDs); and (4) environment-specific (MDe). Each these models were fitted using two kernel methods: a linear Genomic Best Linear Unbiased Predictor, GBLUP (GB),...
The development of homozygous breeding lines in maize may be accelerated through the use haploids. Thus, obtaining and prior identification haploids generated by haploid inducer is an important factor. purpose this study was to identify flow cytometry correlate nuclear DNA content morphological morphometric traits seeds that gave rise them. In addition, molecular markers were used confirm androgenetic nature haploid. obtained derived from cross between inbred line W23 commercial hybrid...
For doubled haploid (DH) production in maize, F1 generation has been the most frequently used for induction due to facility process. However, using F2 would be a good alternative increase genetic variability owing additional recombination meiosis. Our goals were compare effect of and generations on DH tropical germplasm, evaluating R1-navajo expression seeds, working steps methodology, lines obtained. Sources germplasm crossed with tropicalized inducer LI-ESALQ. After harvest, both crosses...
Abstract Reliable discrimination of haploid (H), doubled (DH) and crossing (C) plants in early growth stages could streamline DH production maize. By detecting undesirable sterile H heterozygous C plants, a large proportion resources required for be saved. The goal this study was to evaluate the effectiveness classification V3‐V4 as H, or context using flow cytometry stomata length. As reference classification, we used field score based on plant phenotype commonly applied research. Our...
ABSTRACTArtificial chromosome duplication is one of the most important process in attainment doubled haploids maize. This study aimed to evaluate induction ability inducer line KEMS a tropical climate and test efficiency R1-Navajo marker by flow cytometry two protocols analyze development field. To accomplish this goal, four genotypes (F1 F2 generations) were crossed with haploid KEMS. The seeds obtained selected using subject protocols. Duplication was confirmed cytometry. percentages...
ABSTRACT Macauba ( Acrocomia aculeata ) is a non-domesticated neotropical palm that has been attracting attention for economical use due to its great potential oil production comparable the commercially used Elaeis guineenses ). The discovery of associations between quantitative trait loci and economically important traits represents an advance toward macauba domestication. Pursuing this advance, study performs single-trait multi-trait GWAS models identify candidate genes related in macauba....
Doubled haploid technology has been used by various private companies.However, information regarding chromosome duplication methodologies, particularly those concerning techniques to identify in cells, is limited.Thus, we analyzed and characterized artificially doubled haploids using microsatellites molecular markers, pollen viability, flow cytometry techniques.Evaluated material was obtained two different protocols maize seeds considered haploids, resulting from the cross between inducer...
