The experiment was conducted to evaluate genetic variability, heritability, genetic gain, genetic and phenotypic correlation using path-coefficient analysis for some agronomic and physiology characters of 54 accessions of maize from East Indonesia. The experiment was arranged in a randomized completely block design with tree replications using 54 accesions. Characters observed were plant high/TTM, number of leaves/JDT, number of leaves above ear/JDA, Length of branches part of tassel/PTM, length of peduncle/PMA, length of ear/PTO, diameter of ear/DTO, number of kernel rows per ear/JBT, flowering time of male flower/UBJ, flowering time of female flower/UBB, maturity time/UMT, seed size/UBJ, leaf area index/ILD, and seed yield/BBJ. The result of the experiment indicated that genetic variability, broadsense heritability and genetic gain for all agronomic and phisiology characters were high. Maize seed yield improvement can be effectively done by selecting for number of leaves, maturity time and seed size. Keywords: Genetic variability, heritability, correlation, path-coefficient analysis
