G.  aEstimation of genetic components in popcorn based on the nested design.  c2001  aThe quantification of genetic components in a base population is essential for the definition of the best breeding strategy to maximize the genetic gains. To evaluate several agronomic traits such as grain yield and popping expansion in half-sib and full-sib families derived from an open pollinated popcorn population, this study used a nested design, in two contrasting environments in the Northern Fluminense region of Rio de Janeiro, Brazil.  apopcorn  aGenética  aMilho  aZea Mays  aDesign I  aGenetic components  aGenetic gain  aNested design  aPipoca1 aAMARAL JÚNIOR, A.
