| Summary: | We investigated the agronomic performance of super-sweet corn genotypes. Super-sweet corn genotypes were backcrossed
with regionally adapted field varieties (CIMMYT 8 and Piranão 8). Eight morphological and yield-related traits were evaluated. A
significant effect of interaction was observed between the five groups of genotypes (donor parents; super-sweet backcrossed parents;
super-sweet intervarietal hybrids; common intervarietal corn hybrids; and field corn populations). Despite the low yield of genotype SH2
Piranão, the hybrids resulting from interbreeding of the backcrossed parents for the improvement of super-sweet corn were promising.
The agronomic performance of the super-sweet parents and their hybrids indicates the possibility of breeding lines with high genetic
value to obtain single-cross hybrids and cultivars of super-sweet corn adapted to the northern region of the State of Rio de Janeiro. |
