The characterization of 26 populations with varying levels of exotic germplasm was conducted in two environments representing distinct locations and planting seasons. The whole set was identified by five subsets: I - local adapted germplasm; II - exotic derived from tropical germplasm; III - semi-exotic derived from tropical germplasm; IV - semi-exotic derived from varying proportion of tropical and temperate germplasm; and V - semi-exotic derived from temperate germplasm. In the experiment -I (Anhembi, SP; three replications) the mean yield (EW - ear weight, t ha-1) for the five sets were 9.49, 8.88, 9.11, 8.68 and 8.51; which are equivalent to 79.5, 74.4, 76.3, 72.7 and 71.3 in percent of the hybrid check. Means for other traits (E10-weight of ten ears, EL-ear length, ED - ear diameter, and TB - tassel branch number) were also shown. In the experiment -II (Piracicaba, SP; no replications), the following traits were evaluated: EW, GW (grain weight), GR (grain yield ratio), MF (days to male flowering), and SW (specific weight). A low correlation (0.220) was observed for EW between environments. In general, the populations under study presented a fairly good potential to be used in breeding programs. |
