Genetic parameter estimatives in CMS 35 maize population at Sergipe, Brazil
The objective of this work was to estimate genetic parameters of CMS 35 population submitted to three selection cycles among and within half-sib progenies in Sergipe State, Brazil, in the 1998/2000 period. In each cycle, 196 half-sib progenies were evaluated in a 14x14 simple lattice in two local sites. The recombinations of the selected progenies were made within the same agricultural year, so that one cycle/year/was obtained. Genetic variability was reduced from the cycle I to the cycle II, and it was increased from cycle II to cycle III. The estimated parameters values associated with mean values for production and with the estimated gain for the selection show the genetic potential of CMS 35 population for increasing production and for good adaptability in the Brazilian Northeast region.
