1. Comet and cytogenetic tests as tools for evaluating genomic instability in seeds of Oryza sativa L. and Phaseolus vulgaris L. from gene banks
Abstract This study aimed to assess the feasibility of comet and cytogenetic tests as tools for evaluating genomic instability in seeds of Oryza sativa L. (rice) and Phaseolus vulgaris (beans) L. from gene banks. Rice and beans were exposed to methyl methanesulfonate (MMS) as a reference DNA damaging agent. Seeds of two accessions of rice and beans were obta

2. Uso de nitrogênio no cultivo de arroz irrigado e seus efeitos no solo, na planta e na emissão de óxido nitroso / Use of nitrogen in the cultivation of rice and its effects on soil, lant and nitrous oxide emission
In wetland soils are countless electrochemical changes, among the most influenced by anaerobic conditions is nitrogen. The rice crop also determine changes in the process, either by the nutrient uptake or by changes in the rhizosphere. The nitrogen can guarantee high yields of rice, however, due to the inadequate use of nitrogen can have nitrous oxide, which

5. Genetic parameters in yield recurrent selection familes in carioca type beans.
The objectives of this work were: to estimate genetic parameters; to evaluate families from recurrent selection breeding programs, comprising carioca type beans from Embrapa Rice and Beans Research Center, and to select superior families for the obtainment of lines to intercross to form new selecting populations.

6. Milled rice quality evaluation during storage under different temperature conditions.
Most of Brazilian consumers prefer to eat soft and fluffy cooked rice, especially when it is stored under refrigeration and re-heated. After harvest, some rice varieties, mainly from lowland system, need some weeks or months to reach the desirable cooking grain quality and normally the chemical and sensory analyses take place right after harvest. In order to

7. Evaluation of white common bean genotypes in Brazil.
White grain beans have a great potential in the external market, since grains with that color and large size are well consumed in the United States and Europe. However, the number of cultivars with those characteristics at the farmer?s disposal is scarce; therefore the Embrapa Rice and Beans breeding program has been working on the identification of genotype
