The expansion of agriculture, coupled with the need for sustainable cropping, is one of the greatest challenges of the scientific community working on the generation of new cultivars adapted to abiotic stress conditions. The aim of this study was to evaluate the variability of popcorn lines as to responsiveness and efficiency in phosphorus use, as a first step towards the implementation of a ... more

Edible Grain; Models, Genetic; Plant breeding; Quantitative Trait, Heritable; Selection, Genetic; Selective breeding; Zea mays

Selection indices commonly utilize economic weights, which become arbitrary genetic gains. In popcorn, this is even more evident due to the negative correlation between the main characteristics of economic importance - grain yield and popping expansion. As an option in the use of classical biometrics as a selection index, the optimal procedure restricted maximum likelihood/best linear unbiased ... more

The present study was conducted to investigate the genetic control and to estimate the general and specific combining abilities of popcorn for agronomic attributes and attributes related to resistance to northern leaf blight (NLB). The 56 hybrids (F and reciprocals), together with the eight parent lines and six controls, were evaluated in two harvests, in a randomized-block design with four ... more

Genetic divergence; Microsatellite marker; Specialty maize; Zea mays

In view of the narrow genetic base of popcorn, probably due to its evolution by selection from flint maize types alone, knowledge about genetic divergence is imperative for the formation of heterotic groups. Thus, our objective was to identify heterotic groups of popcorn lines; we did so by exploiting the representative genotype collection of the Active Popcorn ... more

Amino acids; Biofortification; Breeding; nutritional profile of grains; Zea mays

The growing demand for maize creates a challenge for breeders; they need to constantly develop higher yielding and higher quality genotypes. We estimated the most relevant genetic parameters, along with heterosis and variance components. A multivariate approach was used in order to define profiles of narrow sense heritability for yield and nutritional components in ... more

Comet assay; Genetic damage; Genotoxicity; Nicosulfuron; Topramezone; Zea mays

In order to facilitate corn production, herbicides such as nicosulfuron and topramezone are commonly used. Though they offer great advantages, they can affect crop productivity and induce DNA damage. The genotoxic activity of nicosulfuron was evaluated at two concentrations (40,000 and 80,000 ppm) and topramezone at four concentrations (1480, 148, 14.8 and 1.48 ppm ... more

biometric models; trait associations; Zea mays

Corn is considered one of the most important crops in the world agricultural scenario. In order to improve production, it is crucial to understand and quantify the genetic variation involved in the phenotypic manifestation of this species. We evaluated the agronomic performance of open pollinated genotypes, used by small scale family farmers, compared to commercial ... more

Adaptation; Interaction G x E; Zea mays

We evaluated how genetic x environment (G x E) interactions affect grain productivity in corn hybrids grown in traditional and non-traditional environments in the off or “second” season. Adaptability and stability of the hybrids was examined by parametric, nonparametric and multivariate methods. In 2016, 24 hybrids were evaluated in seven environments, in 2017, 13 ... more

Optimization of operations; Production hybrid seed; Zea mays

We evaluated the efficiency of three mechanical detasseling methods on the production of hybrid maize seeds. The experiment was run in the crop season of 2016/2017 in Indianópolis, MG, Brazil. The design used was random blocks, where the treatments corresponded to three detasseling methods: Puller (PUL) - based on only one mechanical detasseling operation, Cutter ... more

Direct and indirect selection; Foliar diseases; Full-sib plants; Genetic parameters; Zea mays

Phenotypic and genotypic correlations of agronomic traits with resistance to phytopathogens can help identify indirect selection criteria for corn yield. The Brazilian corn cultivar NAP5 is resistant to leaf spot and blight disease, while NAP7 is resistant to rust disease. Trials were conducted in two states from February to July 2015. The following traits were ... more
