Abstract
Sweet corn is an important commodity in Indonesia as the second main carbohydrate source after rice. Along with the growth in population, the demand for corn is increasing. Breeding programs to obtain high-yielding varieties are needed to compensate for the lack of higher demand for corn. Selection is the main activity in plant breeding programs that aims to increase the frequency of characters desired to be used as elders in crosses. Selection based on quantitative characters is difficult because many genes are controlled, but the success of selection can be improved by considering genetic parameters such as means, varians, heritability and genetic correlation. The aim of the study was to select sweet corn lines based on genetic parameters that are directly related to the yield. The study was conducted in July 2018 - December 2018 in the Experimental Station of PT. East West Seed Indonesia, Campaka Village, Purwakarta Regency. The genetic material used was 14 MS-Unsika sweet corn lines and 3 commercial sweet corn. The results showed that there was a high diversity of sweet corn lines tested. Characteristics of plant height, ear height, ear diamater, ear length, cob weight per plant, weight of 100 seeds, number of rows per ear had heritability and a high correlation with yield of tons per hectare. The MS 08 line is the best line as a candidate for hybrid parents.
