The objective of this study was to evaluate the genetic advancement of four cycles of selection obtained by recurrent selection family full-sib (RSFFS) with pedigree in the 24 Population. Treatments were divided in cycles (C0, C1, C2, C3 y C4) and three controls. This research was carried out in two localities Villa Ursulo Galván and Rinconada at the State of Veracruz, Mexico. A complete randomized block design was utilized with 10 repetitions. The results obtained were an increased 3.09% in yield, an increased in the number of ears per plant 4.92%, a lesser the stalk lodging 6.06%, and an improvement for husk cover of 12.05%. The gain for linear regression was 282.2 kg/ha/cycle is the same a 5.54%.
