<abstract abstract-type="main"> <title>Abstract</title> <sec id="jsfa6073-sec-0001" sec-type="section"> <title>Background</title> <p> <bold>Grain texture is one of the most important characteristics of bread wheat and has a significant influence on end‐use qualities</bold>.</p> </sec> <sec id="jsfa6073-sec-0002" sec-type="section"> <title>Results</title> <p> <bold>Forty‐three Chinese cultivars were tested under three environments and used to characterise kernel hardness, <italic>Puroindoline‐D1</italic> alleles and Alveograph and Mixolab parameters. The results indicated that SKCS hardness was positively correlated with Alveograph tenacity and <italic>P</italic>/<italic>L</italic> and Mixolab protein weakening (<italic>C2</italic>) and water absorption and negatively correlated with Mixolab starch gelatinisation (<italic>C3</italic>), amylasic activity (<italic>C4</italic>) and starch gelling (<italic>C5</italic>). Variance analysis showed that <italic>Puroindoline‐D1</italic> had a significant impact on SKCS hardness and most Alveograph and Mixolab parameters. Furthermore, among three <italic>Puroindoline‐D1</italic> genotypes, <italic>PINA‐null/Pinb‐D1a</italic> possessed the highest SKCS hardness, Alveograph tenacity and <italic>W</italic> and Mixolab stability and water absorption but the lowest Alveograph extensibility and <italic>G</italic> and Mixolab <italic>C3</italic>, <italic>C4</italic> and <italic>C5</italic>. <italic>Pina‐D1a/Pinb‐D1a</italic> had the lowest SKCS hardness, Alveograph tenacity and <italic>W</italic> and Mixolab <italic>C2</italic>, water absorption and stability but the highest Alveograph extensibility and <italic>G</italic> and Mixolab <italic>C3</italic>, <italic>C4</italic> and <italic>C5.
