Table 4. Association between Pina, Pinb and GSP-1 ABD and Pinb-2 ABD gene expression measurements and SKCS hardness index, at 14 DPA.
No significant association was observed at 30 DPA. Genotypes were grouped into four groups for statistical analysis; all genotypes, non-mutants, Pina-mutants and Pinb-mutants. Additive and interactive effects of gene expression were analysed using linear and polynomial regression model. Only significant associations are listed.
