Genome-wide association study for grain yield and component traits in wheat (Triticum aestivum L.)

The study material in GWAS panel with 280 common bread wheat genotypes was selected from All India Coordinated Research Project on Wheat and Barley to map the genomic regions governing days to heading (DH), grain filling duration (GFD), grain number per spike (GNPS), grain weight per spike (GWPS), plant height (PH), and grain yield (GY).
Phenotypic data:
The GWAS panel was evaluated at five different environments during the 2020-21 Rabi (winter) season: E1-University of Agricultural Sciences, research farm, Dharwad (15°29'20.71\"N, 74°59'3.35\"E, 750m AMSL), E2-ICAR-Indian Agricultural Research Institute, New Delhi (28°38′30.5″N, 77°09′58.2″E, 228 m AMSL), E3-Indian Agricultural Research Institute, Jharkhand (24°16'58.4\"N, 85°21'16.1\"E, 651m AMSL), E4-ICAR-Indian Institute of Wheat and Barley, Karnal (29°41'8.2644''N, 76°59'25.9692''E,  250m AMSL), and E5-Punjab Agricultural University, Ludhiana (30o54' N, 75o48'E, 247m AMSL). The genotypes were planted in an augmented block design along ...
