Combining ability is essential for hybrid breeding in crops. However, the genetic basis of combining ability remains unclear and has been seldom investigated. Identifying molecular markers associated with this complex trait would help to understand its genetic basis and provide useful information for hybrid breeding in maize. In this study, we identified(More)
Zinc (Zn) and iron (Fe) are essential micronutrients for plant growth and development, their deficiency or excess severely impaired physiological and biochemical reactions of plants. Therefore, a tightly controlled zinc and iron uptake and homeostasis network has been evolved in plants. The Zinc-regulated transporters, Iron-regulated transporter-like(More)
Micronutrient malnutrition, especially zinc (Zn) and iron (Fe) deficiency in diets, has aroused worldwide attention. Biofortification of food crops has been considered as a promising approach for alleviating this deficiency. Quantitative trait locus (QTL) analysis was performed to dissect the genetic mechanism of Zn and Fe content in maize grains using a(More)
Evaluation of combining ability is a crucial process in hybrid breeding, and dissection of the genetic basis of combining ability will facilitate hybrid breeding. In this study, molecular markers significantly associated with general combining ability (GCA) of seven yield-related traits and the traits per se were detected in a set of maize introgression(More)
Grain filling rate (GFR) and grain drying rate (GDR) are important for maize final yield determination and adaptability. To identify marker-trait associations and candidate genes, a diverse maize population consisting of 290 inbred lines was used and a genome-wide association study was conducted with 201 SSR markers. GFR and GDR of all stages showed broad(More)
A dissection of the genetic regulation of protein, oil and starch contents in maize (Zea mays L.) kernels will enhance high-quality breeding. The objective of the present research was to detect the quantitative trait loci (QTL) controlling protein, oil, starch and lysine contents in maize kernels and to dissect their inheritable relationships and basis. A(More)
Grain zinc and iron concentration is a complex trait that is controlled by quantitative trait loci (QTL) and is important for maintaining body health. Despite the substantial effort that has been put into identifying QTL for grain zinc and iron concentration, the integration of independent QTL is useful for understanding the genetic foundation of traits.(More)
