Evaluation of synthetic hexaploid wheat (Triticum aestivum) derived RILs for kernel traits

In bread wheat (Triticum aestivum L.), kernel parameters are significant grain quality characteristics that affect yield and milling as well market price. Utilization of synthetic hexaploid donor to harness the diverse alleles for broadening genetic base is a novel breeding strategy programs across globe. An experiment was conducted during winter (rabi) season 2017–18 2018–19 at research farm ICAR-Indian Agricultural Research Institute, New Delhi evaluate 188 recombinant inbred lines (RILs) which were derived from HD 2932 (Indian cultivar) Synthetic 46 (Syn 46: donor) identify effect on parameters. Kernel like length (KL), width (KW), thickness (KT) thousand weight (TKW) studied. Syn had larger kernels high TKW with respect 2932. Significant variation all traits observed in population transgressive segregants. this RILs (188) KL ranged 5.13–7.5 mm, KW 2.26–3.9 KT 2.57–3.41 25.2–53.17 g. Correlation analysis showed positive correlation KT. Potential identified desirable allelic combinations may be used future programs, contrasting create nested further generation variability.
