Table 4 Significance and extent (as genetic correlation rg for genotype response across environments) of genotype × environment interaction across pairs of test environments, for traits of 306 pea lines belonging to three RIL populations

From: Pea genomic selection for Italian environments

  Years 2013–14 vs 2014–15 in Lodia Lodi vs Perugia in 2013-14a
Trait P value r g P value r g
Grain yield ** 0.325 ** 0.822
Onset of flowering ** 0.889 ** 0.955
Lodging susceptibility ** 0.639 NS 0.980
Individual seed weight ** 0.879 ** 0.953
  1. a NS and **: not significant at P < 0.05 and significant at P < 0.01, respectively; rg always different from zero (P < 0.01)
