The research aims to see the variability value, heritability and genetic progress of the F2 maize population which is the result of crossing BSM0729S3-A with BAP27799-1. The final goal of this research series is to assemble high yielding composite maize. The study was conducted from April to July 2019 on the community fields, Nagari Sitiung, Sitiung District, Dharmasraya District, West Sumatra. The material used was maize seed population F2 (the result of crossing BSM0729S3-A with BAP27799-1) and the two elders were BSM0729S3-A and BAP27799-1. The observed variables were plant height, age of anthesis, age of hair appearing, cob weight without maize husk, cob length, cob diameter, and seed weight per cob. The results of the analysis of the variability values showed that all the observed variables had a wide variability, whereas based on the results of the analysis of the heritability values showed that (except for the length of the cob) all the observed variables had high heritability values. Based on the results of the analysis of the genetic progress value, the plant height variable, the cob weight without maize husk, the diameter of the cob, and the weight of the cobs of seed have a high genetic progress value, the anthesis age variable and the age of hair appearing have a high genetic progress value, while the length of the cob variable has a value low genetic progress. It can be concluded that the selection activities in the F2 population to get high-yielding maize seeds can be carried out effectively and efficiently.
