Abstract

Few corn producers can purchase certified seed of hybrids, so the other option for low-income farmers is to acquire certified seed of free-pollinated varieties. In Chiapas, the variety V-526 was released in 1983 and was very appreciated by the producers reaching up to 50 000 ha in its first year with certified seed. In 2000, a scheme of combined selection of families of complete siblings was started on V-526 in order to renew it, increasing its yield potential, but without changing its phenotypic characteristics of plant and cob. After three cycles of selection the experimental varieties formed were evaluated and one of them was detected as outstanding, which was called V562. This new variety can produce up to 1.4 t more than the V-526, with a potential yield of 7.8 t ha-1, under good weather conditions. Its grain characteristics are excellent for making white tortillas and good quality.
