A ferrugem da cana-de-acucar foi pela primeira vez no Brasil em novembro de 1986, na regiao sudeste e em pouco tempo se disseminou para toda a regiao meridional do pais. Em julho de 1987 ela foi constatada em Pernambuco, na regiao norte. Como as condicoes prevalentes foram especialmente favoravies a doenca, a ferrugem causou serias preocupacoes aos produtores. Felizmente, as principais variedades comerciais bem novas haviam sido ja testadas no exterior e a maioria tinha demonstrado bom nivel de resistencia. Estudos iniciais tem sido direcionados para conhecimento dos sintomas e da reacao das variedades. As avaliacoes de progenies e a selecao para a resistencia a ferrugem tem sido feitas em condicoes de infeccao natural no campo. Estudos morfologicos do fungo mostraram que o agente causal da ferrugem no Brasil e Puccinio melanocephala e, por evidencias indiretas, se assume que ele chegou ao Brasil atraves de correntes aereas vindas da Africa. Apesar das perdas diretas em canaviais comerciais, em termos medios, possam ser consideradas pequenas no primeiro ano de ocorrencia da ferrugem, os produtores nao deverao aumentar a area de plantio das variedades suscetiveis. |

The controlled deterioration test (CD) is an ageing technique similar to the accelerated ageing test (AA) that permit better seed moisture and temperature control during the ageing period. The seed moisture content in the CD test is adjusted previously, providing a uniform stress in all seeds under evaluation this does not occur in the AA test, where each seed moisture content is raised without control during the test period, until it reaches the equilibrium moisture content with the chamber environment. Thus, seeds may reach the equilibrium at different times and they are submitted to distinct level of stress, as well as damaged by the presence of storage fungi (e. g., Aspergillus and Penicilium), that may occur during the test conditions used for screening genotypes for seed quality (41ºC during 72 or 96 hours). Therefore, seed treatment is required and may interfere negatively in the selection process. The research was conducted with 29 seed lots of 13 cultivars of five vigor levels according to the tetrazolium test rank as follows: <49%, 50-59%, 60-74%, 75-84% and >85%. The experimental design was a completely randomized design and the means were compared by the Tukey test at 5% of probability. The following conclusions could drawn: i) the CD test is reliable to identify distinct vigor levels of soybean seeds, which may result from different levels of seed quality among seed lots and cultivars; ii) the accurate information provided by the CD test fulfill the requirement for use in screening soybean genotypes for high seed quality.
