traits such as soluble solids content, fruit acidity, ph, fruit lycopene concentration, fruit beta-caroteneconcentration, and fruit xanthophyll concentration are very important to the tomato industry. in this study,quantitative trait loci (qtl) analysis of these traits was performed using a recombinant inbred line (ril)population derived from a cross between a tomato (lycopersiconesculentum mil...

in order to map qtls controlling phonological traits of barley under normal and drought stress conditions, an experiment was conducted by 72 doubled-haploid lines and their two parents (steptoe and morex), at the research farm, college of agriculture, university of zabol, in 2011. the experiment was arranged in completely randomized block designs with three replications under normal irrigation ...

to investigate variation and detect of genomic regions controlling quality and quantity of malt extract in barely, a study was conducted using a set of 72 double haploid barley lines as well as their parents (stepto & morex) at experimental stations of university of mahabad and agricultural research center of mian'doab in rcbd with two replications during cropping season (2011-12). differe...

Plant traits are important indices for regulating and controlling yield ability in soybean varieties. It is important to comprehensively study the quantitative trait locus (QTL) mapping for soybean plant traits, cloning related genes, and marker assistant breeding. In this study, 236 F2 generation plants and a derivative group were constructed by using Jiyu50 and Jinong18, obtained from Jilin P...

Drosophila melanogaster is a cosmopolitan species that colonizes a great variety of environments. One trait that shows abundant evidence for naturally segregating genetic variance in different populations of D. melanogaster is cold tolerance. Previous work has found quantitative trait loci (QTL) exclusively on the second and the third chromosomes. To gain insight into the genetic architecture o...

This study investigates the preparation of PbSe-ZnSe composite thin films by simultaneous hot-wall deposition (HWD) from multiple resources. The XRD result reveals that the solubility limit of Pb in ZnSe is quite narrow, less than 1 mol%, with obvious phase-separation in the composite thin films. A nanoscale elemental mapping of the film containing 5 mol% PbSe indicates that isolated PbSe nanoc...

Quantitative trait loci (QTL) mapping for bean traits and the number of ovules per ovary was carried out in cocoa (Theobroma cacao L.) using three test-cross progenies derived from crosses between a lower Amazon Forastero male parent (Catongo) and three female parents: one upper Amazon Forastero (IMC78) and two Trinitario (DR1 and S52). RFLP (restriction fragment length polymorphism), microsate...

Diploid A genome cottons are grown for their natural fiber in drought prone areas of Asia. Although they possess inferior fiber qualities to cultivated Upland and Pima cotton, their value lies in their inherent resistance to pests and diseases. Molecular linkage maps provide essential tools for plant genetic research, facilitating quantitative trait locus (QTL) mapping, marker-assisted selectio...

Heterosis is widely used in breeding, but the genetic basis of this biological phenomenon has not been elucidated. We postulate that additive and dominance genetic effects as well as two-locus interactions estimated in classical QTL analyses are not sufficient for quantifying the contributions of QTL to heterosis. A general theoretical framework for determining the contributions of different ty...
