Abstract
Some temperate areas of the world behave as sub-tropical due to greenhouse effect and the global warming. Therefore, more temperate genotypes show an important decrease in yield and dry matter production as consequence of heat stress. The objective of this work was to evaluate the behavior of tropical maize genotypes under these climatic conditions and the feasibility of its utilization for silage production. Fifteen commercial hybrids were evaluated, five temperate and ten tropical, for fresh and dry matter production, grain yield, harvest index, plant and ear height, dry matter digestibility and crude protein in a field trail. Tropical genotypes showed a good behavior for all traits, inclusively those related with forage quality. Results attested that it is possible to increase silage production under these climatic conditions by introducing tropical genotypes into plant breeding programs.
期刊介绍：
The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL.
It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
