In an attempt to provide regionalized information about maize genotypes?
response to corn stunt disease complex, this study evaluated the corn stunt disease
severity and productivity of conventional (7) and transgenic (11) maize genotypes
under natural infestation of its insect vector, Dalbulus maidis (Hemiptera: Cicadellidae).
The work was carried out in Campos Novos, SC, Brazil, during the 2020/2021 crop
season. In a randomized block design, the genotypes were sowed in experimental
plots of 14 m2, with four replicates (plot) per genotype. At 90 days after sowing, the
severity of corn stunt disease was analyzed using a visual symptoms scale, while the
maize productivity was assessed at physiological maturation. There was variability for
response to stunt disease in the genotypes and a negative correlation between severity
and grain yield. Among the conventional genotypes, P3456, FS055, SCS154 Fortuna,
SCS156 Colorado, and SCS155 Catarina had lower severity of corn stunt disease. For
the transgenic genotypes, AS1757 PRO3 and P3551 PWU were more resistant, while
B2418 VYHR, AG9025 PRO3, and P1225 VYHR had high corn stunt disease severity.
The corn stunt severity varied from 1 (absence of symptoms) in P3551 PWU to 4.8
(more than 75% of leaves with symptoms) in P1225 VYHR, while the lowest and
highest yields were obtained for BG7056 (1,253.7 kg.ha-1) and P3016 VYHR (9,794.6
kg.ha-1), respectively. The genotypes with low corn stunt disease severity are suitable
options for sowing in the Midwest region of Santa Catarina, Brazil, in conditions of high
population pressure of D. maidis. MenosIn an attempt to provide regionalized information about maize genotypes?
