This research aims to see the phenotypic appearance of selected families from the basic population of local waxy corn of South Sulawesi which is back cross with the parents. The technique of crosses used is repeated selection that is to make a cross between selected families (recombination) by means of free crossing. The number of cross-test of 5 selected families and 5 varieties of comparison (parents) with 2 replications. Each replica was planted with 10 lines of 20 lines of with 20 cm x 50 cm spacing), the total number of plants in this research were 400 plants. Each line represented 5 sample plants, so the total sample of 200 plants. The results showed that from 5 selected families who crossed with their parents as a whole can improve the phenotype character. The selected local waxy corn has a superior appearance of the phenotype character. Of the 200 plant samples, there are 75 plants that have superior appearance (better phenotype appearance than their parents) on the character : plant height , the height of cob location, male flowering, female flowering, and husk cover.
