    Mapping of the QTLs governing grain nutrients in wheat (Triticum aestivum L.) under nitrogen treatment using high-density SNP markers by Animireddy China Malakondaiah, Sudhir Kumar, Hari Krishna, Biswabiplab Singh, Sukumar Taria, Monika Dalal, R. Dhandapani, Lekshmy Sathee, Renu Pandey, Ranjeet Ranjan Kumar, Viswanathan Chinnusamy

    Published 2025-05-01
    “…According to recent studies, the optimum application of nitrogen (N) fertilizers can significantly enhance the micronutrient uptake and accumulation in wheat grains.MethodsThe aims of this study were to identify superior wheat recombinant inbred lines (RILs) of RAJ3765 × HD2329 with high nutrients in grain using the multi-trait genotype–ideotype distance index (MGIDI) and to identify quantitative trait loci (QTLs)/genes associated with grain nutrient content using a single-nucleotide polymorphism (SNP)-based genetic linkage map. The parents and their RIL population were grown under control and nitrogen-deficient (NT) conditions, and nutrient content was determined using inductively coupled plasma optical emission spectroscopy (ICP-OES).Results and discussionAnalysis of variance and descriptive statistics showed a significant difference among all the nutrients. …”
