Assessment of genetic parameters of degradability in maize grains due to indentation scores
Provedor de dados: Scientia Agricola

Maize (Zea mays L.) cultivars with dent grains present higher starch and dry matter ruminal degradability than those with flint grains. This study aimed to assess genetic parameters of degradability in maize grains of different textures and to verify whether there is an association between grain indentation score and ruminal dry matter (RDM) degradability. The evaluated progenies were obtained from the cross between the varieties Cristal (flint) and Cunha (dent), previously selected for grain hardness. Progenies were evaluated for an indentation score using a visual grading scale ranging from 1 (flint) to 5 (dent). To assess the RDM degradability, 5 g were cut into halves, weighed (five grams), stored in bags made of 100% "failet" cloth and incubated for...

Since every year public and private companies bring many genotypes of maize to the market, the suitability of these genotypes for the production of silage should be evaluated. Current study evaluates the agronomic and chemical characteristics of early-normal cycle maize genotypes as well as assesses whether the genetic bases (single, double, and triple hybrids, as well as varieties and intervarietal genotypes) and the grain hardness (hard, semi-hard and dentate) modify the indication of maize genotypes for silage. The experiment was conducted at the Universidade Tecnológica Federal do Paraná, campus Dois Vizinhos, Paraná State, Brazil. Thirty-six genotypes were evaluated by a simple lattice design. Grains were harvested at the pasty to farinaceous stage...
