| The growth of thirty-four Lentinula edodes strains submitted to different mycelial cultivation conditions (pH and temperature) was evaluated and strain variability was assessed by RAPD molecular markers. The growth at three pH values (5, 6 and 7) and four different temperatures (16, 25, 28 and 37ºC) was measured using the in vitro mycelial development rate and water retention as parameters. Mycelial cultivation was successful at all pH tested, while the ideal temperature for mycelial cultivation ranged between 25 and 28ºC. The water content was lower in strains grown at 37ºC. Among 20 OPA primers (Operon Technologies, Inc.) used for the RAPD analyses, seventeen presented good polymorphism (OPA01 to OPA05, OPA07 to OPA14, OPA17 to OPA20). The clustering... |

| More erect plant architecture has been a goal in the development of bean cultivars. Aiming to obtain more information about genetic control of traits related to plant architecture, this work was carried out between August 1995 and July 1997 in the southern and Alto São Francisco regions, in the State of Minas Gerais, Brazil. Initially, analyses were performed with individual plants of parents and different segregant generations from the crosses Carioca-MG x H-4 and Carioca x FT-Tarumã. In these experiments, besides degree of erectness, other traits were evaluated: ramification degree, internode length, internode diameter and height of insertion of the first pod. Mean and variance components and heritability at an individual level were estimated. Later,... |

| O objetivo deste trabalho foi selecionar famílias de milho derivadas do retrocruzamento entre o composto "NAP Corn Stunt" (genitor doador) e linhagens-elite (genitores recorrentes), quanto à produtividade de grãos e à resistência a enfezamentos, e avaliar a eficiência do emprego de marcadores moleculares para avaliação fenotípica na seleção de genótipos com alta produtividade de grãos. Foram avaliados 100 genótipos, em cinco condições ambientais, na safra agrícola 2009/2010. Foram selecionadas famílias RC1F2, que aliam a alta produtividade dos genitores recorrentes à resistência aos enfezamentos, presente no genitor doador. As famílias selecionadas quanto ao desempenho agronômico e à resistência aos enfezamentos foram: L228-3-324-S, L228-3-237-R,... |
