Avaliação do progresso genético obtido em 22 anos no melhoramento do arroz irrigado em Minas Gerais

O objetivo deste trabalho foi avaliar o desempenho do programa de melhoramento genético do arroz irrigado, no Estado de Minas Gerais. Foram utilizados os dados de produtividade de grãos dos ensaios comparativos avançados de cultivares e linhagens de arroz irrigado, conduzidos em várias microrregiões do Estado de Minas Gerais, durante o período de 1974/75 a 1995/96. O ganho genético médio obtido em todo o período foi de 33 kg/ha/ano (0,98%), sendo altamente significativo (P<0,01). O período de 22 anos foi subdividido em duas fases: na primeira (1974/75 a 1979/80), observou-se um ganho de 203 kg/ha/ano (6,06%), o qual foi altamente significativo, e a segunda fase (1980/81 a 1995/96) apresentou um ganho de 15 kg/ha/ano (0,25%), o qual não foi significativo. Atribui-se o alto ganho da primeira fase à substituição de cultivares tradicionais de porte alto e de baixo potencial produtivo por cultivares melhoradas, como Inca, BG 90-2 e MG 2. Na segunda fase do programa, deu-se um enfoque maior à obtenção de cultivares mais resistentes a doenças e com melhor qualidade de grãos, resultando em ganhos não-significativos quanto à produtividade de grãos.

Identification of Conifer Trees in Iowa, September 22, 1998

This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fascicles of two or more. Remember, vegetative characteristics are quite variable; use more than one specimen for comparison.

Iowa Privacy Task Force Final Report, January 22, 2002

In appointing the Iowa Privacy Task Force, Governor Vilsack sought to obtain the opinions of both average Iowa citizens and businesses and professionals that work with health and financial information. The Governor recognized that the free flow of information is essential to the vitality of the Iowa economy. At the same time, he also recognized the legitimate fears and concerns of Iowa citizens with the potential loss of privacy inherent in the vast new information flows in this new economy. In order to obtain broad and balanced input, the Governor appointed half the members of the Task Force to represent average Iowa citizens. The other half of the Task Force was appointed with representatives of the financial services industry, providers of health care and the health insurance industry. The Task Force was further balanced to represent the different geographic regions of the state and gender. A total of 32 members were appointed to the Task Force.
