Wheat Genotype Phenotypes Under Nitrogen Treatments in Pakistan, 2021-2023

323 wheat genotypes were evaluated under two nitrogen treatments (N100 and N50) across two locations in Pakistan over two consecutive growing years. The dataset contains phenotypic measurements including days to flowering, flag leaf area, peduncle length, spike length, plant height, straw yield, grain yield, and thousand grain weight. The study was supported by the Natural Environment Research Council.

Use Cases

• Analyze grain yield and straw yield responses to N100 and N50 nitrogen treatments across 323 genotypes.
• Model the relationship between plant height, spike length, and thousand grain weight under different nitrogen regimes.
• Assess genotype-by-environment interactions using days to flowering and flag leaf area data from two locations over two years.
• Identify nitrogen use efficiency traits by correlating peduncle length and grain yield measurements under reduced nitrogen (N50).

Strengths

• Data covers 323 distinct wheat genotypes, providing substantial genetic diversity.
• Experiments were replicated across two locations (Faisalabad and Islamabad) and two growing seasons (2021-22 and 2022 23).
• Includes eight key phenotypic parameters measured under controlled nitrogen treatment levels.

Limitations

• The dataset is embargoed and not accessible for public use until June 1, 2026.
• Experimental design and replication counts (4 and 3) differ between the two locations, which may complicate direct comparisons.
• Limited to two specific geographic locations in Pakistan, reducing generalizability to other wheat-growing regions.
