Testcross performance of Doubled Haploids versus S2, S4, and S6 selfing generation in a maize population for the subtropics in México

Maize (Zea mays) hybrid breeding programs are increasingly using Double Haploid (DH) technology; however, in developing countries like in the subtropics, its use is still limited.
