Variability, Association and Selection of Promising Characters for Breeding Creole Maize

Genetic variability is the main characteristic when seeking to select promising genotypes for plant breeding. Thus, objective of this work was investigate genetic in agronomic and morphological characteristics traditional varieties maize, addition determining degree association selection variety characters be explored programs breeding Creole maize. The experiment conducted at Federal University Acre (UFAC), Rio Branco - Acre, 2017/2018 harvest period. A randomized block design used, with five replications. treatments were four maize (V1, V2, V3 V4) from Vale do Juruá region another hybrid cultivar LG 3040 (HI). morpho-agronomic evaluated useful area plots: days silking (DS), anthesis (DA), height (PH) ear insertion (HEI), stem diameter (SD), mass (ME), length (LE), (DE), total grain (TGM), 100 (M100G), moisture (GM) productivity (GP). data subjected analysis variance comparison means. values genotypic phenotypic also estimated, heritability broad sense, accuracy, phenotypic, environmental correlation, principal component (PCA). Variations found between their interrelations, showing greater influence ME, PH, TGM, M100G, DE GP expression phenotype. Therefore, it concluded that there evaluated, emphasis V4 showed superior performance allowing direct SD, TGM M100G incorporated into an program.
