Quantitative trait locus (QTL) analysis of fruit-quality traits for mandarin breeding in Japan
Tree Genetics & Genomes, 2017The improvement of fruit quality is an important objective in citrus breeding. Using an F1 segregating population from a cross between citrus cultivars ‘Harehime’ (‘E647’—‘Kiyomi’ [Citrus unshiu Marcow. ‘Miyagawa Wase’ × Citrus sinensis (L.) Osbeck ‘Trovita’] × ‘Osceola’—a cultivar of clementine [Citrus clementina hort.

Integrating spatial variations in the vineyard to enhance quantitative trait locus (QTL) detection
Acta Horticulturae, 2019French vineyards are often located on the least fertile lands, generally more heterogeneous than lands devoted to food crops. The detection of quantitative trait loci (QTLs) is all the more precise, as the number of genotypes studied is high, but increasing the size of experimental plots means taking the risk of exploring more spatial heterogeneity ...

Pyramiding Quantitative Trait Locus (QTL) Alleles Determining Resistance to Barley Stripe Rust
Crop Science, 2003Durable disease resistance may be achieved by pyramiding multiple qualitative resistance genes in single genotypes and by using quantitative resistance (QR) genes. Quantitative trait locus (QTL) analysis tools can be used to find determinants of QR. Resistance QTL pyramids may also lead to durable resistance, and they provide independent validation of ...

Sugar Tech, 2018
Quantitative trait locus (QTL) mapping of sugar yield-related traits can promote the discovery of new sugar yield-related genes. Subsequently, marker-assisted selection (MAS) can be used to breed new high-yield sugar beet varieties. In this study, we observed the F1 population (219 individuals) from a cross of 3a (high-yield, low-sugar, diploid ...

Theoretical and Applied Genetics, 1989
A new method is described to obtain maximum likelihood estimates of recombination frequencies between quantitative trait loci (QTL) and marker gene loci; it is based on Fisher's method of scoring and numerical differentiation. The method is applied to data from chromosome-doubled monoploid lines of barley originating from the F1 generation of a cross ...

The efficiency of marker-assisted backcross for the introgression of a quantitative trait locus (QTL) from a donor line into a recipient line depends on the stability of QTL expression. QTLs for six quality traits in tomato (fruit weight, firmness, locule number, soluble solid content, sugar content and titratable acidity) were studied in order to ...

Quantitative trait locus (QTL) analysis of pod related traits in different environments in soybean
2013Soybean is an important crop, whose most agronomic traits are quantitative inherited. Mapping of these quantitative trait loci in soybean genes is importance for various applications. A F2:15 RIL population containing 149 lines derived from a cross between Charleston as female and Dongnong 594 as male parent were used for mapping of the QTL of pod ...

Um die Markerdichte von existierenden genetischen Karten der Gerste (Hordeum vulgare L.) zu erhöhen, wurde ein neues Set von Mikrosatellitenmarkern mit Dinukleotidmotiven aus genomischen Klonen entwickelt. Von insgesamt 254 getesteten Primerpaaren, wurden 167 Primerpaare als funktional klassifiziert, nachdem sie auf sechs Gerstensorten und drei ...
