The increasing living standard of customers has resulted in a demand for the improvement of the cooking, eating, and appearance quality of rice grains, which have become a priority for rice breeders and geneticists. In this study, a double haploid population derived from the cross between japonica CJ06 and indica TN1 was used to analyze the quantitative trait loci (QTLs) for amylose content, gel consistency...
Chromium contamination in soil has become a severe threat to crop production and food safety. The experiment was conducted using a rice DH population to detect the QTLs associated with Cr tolerance. Seventeen putative QTLs associated with growth traits included three additive loci and fourteen epistatic loci. These loci were distributed on 11 rice chromosomes, and their contribution to the phenotypic...
Low grain cadmium (Cd) and high grain zinc (Zn) rice cultivars have become the current rice breeding objectives. However, the genetic control of Cd and Zn concentrations in brown rice remains poorly understood, especially when grown in Cd-contaminated soil. In this study, quantitative trait loci (QTLs) associated with grain Cd and Zn concentrations and Cd/Zn ratio were identified using a doubled haploid...
Identification of Cr-tolerant lines in a rice DH population was conducted based on the modified weighted function analysis. The significant difference was found between the two parents and among DH population lines, with lines 117, 101 and parent ZYQ8 showing the high Cr tolerance, lines 41 and 49 showing Cr sensitivity. A dramatic difference also existed in Cr accumulation of plant tissues, with...
Cadmium (Cd) is a non-essential element and toxic to plants. To investigate the genetics of Cd tolerance and accumulation in rice, quantitative trait loci (QTL) associated with Cd tolerance and accumulation at the seedling stage were mapped using a doubled haploid (DH) population derived from a cross between a japonica JX17 and an indica ZYQ8. A total of 22 QTLs were found to be associated with shoot...
Salinity is a major abiotic stress to barley (Hordum vulgare L.) growth and yield. In the current study, quantitative trait loci (QTL) for yield and physiological components at the late growth stage under salt stress and non-stress environments were determined in barley using a double haploid population derived from a cross between CM72 (salt-tolerant) and Gairdner (salt-sensitive). A total of 30...
