Abstract
Abstract. Testing of lines crossed with superior varieties makes it easier for plant breeders to develop hybrid maize. This study aims to determine heritability, genetic diversity and correlation in F1 maize from line x tester crosses. This research was conducted at the Bajeng Experimental Garden, Serelalia Research Institute, Pabentengan, Bajeng District, Gowa Regency, South Sulawesi Province. This research was arranged in Line x Tester Cross Design and Randomized Block Design as environmental design. Research factors Information on genetic variance, heritability, and correlation between parameters. Stem diameter (61.00%), ear length (88.62%), ear diameter (68.79%), and production (86.74%) showed high heritability values. The high heritability value indicates the effectiveness of the breeding program. Production parameters were highly correlated with plant height, stem diameter, and ear length parameters. The conclusion of this study is that the characters that have a positive correlation can be used in the synthetic corn development program.
