Abstract
Given the importance of early cold tolerance in maize (Zea mays L.), we previously conducted a divergent selection for low (L) and high (H) cold tolerance at germination. The source population was the F2 of B73 9 IABO78 single cross. Selection was first conducted as recurrent selection (four cycles) and then in inbreeding (three generations). Ten lines were finally selected for L and ten for H; these lines were then evaluated to investigate: (i) their field cold tolerance in the early autotrophic phase and the relationship with the cold tolerance expressed at emergence and in the heterotrophic phase; (ii) the inheritance of these cold tolerance traits; (iii) their agronomic performance as lines per se and as crosses; (iv) their SNP-based genetic characterization. For all cold tolerance traits, the H group of lines was superior to the L group; selection responses were often symmetric, suggesting the prevalence of additive effects....
