Abstract: The objective of this work was to evaluate the yield performance, adaptability, and stability of corn (Zea mays) topcross hybrids in nine environments in Brazil, in order to select inbred lines, testers, and promising hybrid combinations for these environments in the second crop season. The trials were carried out during the second crop season of 2017, in six sites in the state of Paraná and three in the state of Mato Grosso do Sul, Brazil. Sixty-six single-cross hybrids, made up of 33 inbred lines crossed with two testers, were evaluated. The stability of the genotypes was assessed by the Schmidt & Cruz method and by the additive main effects and multiplicative interaction (AMMI) methodology. In addition, the genetic parameters and the general combining ability of the testers were estimated. Tester 2 is the most adapted to discriminate inbred lines in the second-crop environments. Inbred lines 12, 21, 23, and 32 are recommended for obtaining hybrids to be cultivated in the second crop season due to their good adaptability and stability and high yield in the crosses in which they participated. The HS123, HS223, and HS232 hybrids present the best performance and are the most recommended for the second-crop environments.

Sweet corn differs from field corn in many important traits. So its breeding although includes some standard procedures demand application of techniques that are important for determining special traits, all because of the specificity of its usage. Application of molecular markers becomes almost a necessity for the breeding of sweet corn, especially because this is the type of maize in which still no definitive heterotic patterns have been determined. So getting to know genetic divergence of the sweet corn inbred lines is of great importance for its breeding. In this paper we analyzed genetic similarity of six sweet corn inbreds based on SSR markers. 40 SSR primers were used in DNA amplification. Results were compared and correlated with the data on specific combining ability, obtained by the diallel analysis. The results of SCA were in concurrence with genetic similarity. Values of rank correlation coefficient were negative, indicating that more similar inbred lines had smaller estimates of SCA, and lines that were less similar had higher estimates of SCA. Rank correlation coefficient between SCA and GS according to Dice coefficient was between -0,16 and -0,57*.

ABSTRACT The aim of this study was to select S3 progenies of super sweet corn based on agronomic performance, evaluated in topcrosses with the narrow genetic base tester Honey Sweeter (Seminis®). The experiment was carried out in Guarapuava-PR. We evaluated 22 topcross hybrids and three checks, in two sowing times, in randomized blocks design with three replications. Six traits were evaluated: total yield of husked ears, commercial yield of husked ears, grain yield, grain length, ear diameter and total soluble solids content. Considering the set of evaluated traits, the topcrosses with progenies D2-07, D3-28, D4-53 and D5-24 were superior to the others; therefore, these progenies should continue in the inbreeding process and be evaluated in crosses with elite inbred lines with potential to generate competitive super sweet corn single hybrids.

The availability of varieties having high-yielding potential and good horticultural characteristics under organic environment is prerequisite for successful organic sweet corn production. Objective of this study was to estimate the general and specific combining abilities of ear characteristics in eight sweet corn inbred lines under organic cropping system. Seeds of 64 genotypes generated from a full diallel crossing scheme of the inbred lines were planted on the experimental plots in a randomized complete block design with 3 replications. Organic managements were practiced during the crop production. Analysis of variance showed highly significant variabilities among the genotypes for ear length, unhusked ear diameter, husked ear diameter, kernel row number, and ear weight. Analyisis of combining ability components revealed that both additive and non-addive gene actions played important roles in the expression of those traits, while reciprocal effect played a minor role in husked ear diameter expression. Based on their general combining abilities, Caps 17A, Caps 17B, and Caps 5 were considered as good combiners for the development high-yielding hybrid varieties under organic cropping system. Caps 2 x Caps 3 was the hybrid with the highest and positive specific combining ability for most of the characters studied.
