| O objetivo deste estudo foi a caracterização fenotípica e molecular de 31 genótipos de feijão do tipo carioca, quanto à resistência aos patógenos da antracnose, ferrugem e mancha-angular. Foram realizadas inoculações com 13 patótipos de Colletotrichum lindemuthianum, dois de Uromyces appendiculatus e sete de Pseudocercospora griseola. Na caracterização molecular, foram utilizados cinco marcadores moleculares previamente identificados, ligados a diferentes alelos de resistência aos patógenos. Sete genótipos apresentaram resistência a 12 patótipos de C. lindemuthianum. Nove genótipos apresentaram resistência a cinco patótipos de P. griseola. Dez genótipos foram resistentes aos patótipos de U. appendiculatus. As linhagens VC 2, VC 3 e VC 5, além da Rudá-R... |

| The genotypic variability in molybdenum (Mo) accumulation in common bean seeds has been demonstrated in cases in which soil is the main Mo source, but this variability is yet unknown when Mo is foliar-applied. Therefore, seed Mo concentrations (SMoCc) and seed Mo contents (SMoCt) of 12 genotypes were determined in four experiments in the Zona da Mata, Minas Gerais, Brazil, in which plants were sprayed with 600 g ha-1 Mo. For comparison, two additional experiments without external Mo were conducted. Without Mo application, the average SMoCc was undetectable or 2.83 µg g-1, without significant differences among genotypes. On average, with Mo applications, SMoCc ranged from 14.7 to 25.0 µg g-1 and SMoCt, from 3.94 to 6.84 µg. 'Majestoso' was among the... |

| With the purpose to evaluate the intensity of angular leaf spot (ALS) and anthracnose (ANT) on pods, nine genotypes of common bean were planted in three cropping systems: monocrop (MC), monocrop grown on trellises (MCT), and intercrop with maize (ICM). In MC, beans were planted 0.5 m apart. Trelisses were set up with 1.8 m high bamboos and beans were sown 0.65 m apart. In ICM, beans were planted simultaneously with maize and in its rows. This cereal was sown 1.0 m apart with four plants per meter. Each cropping system was an independent trial installed close to each other. Climbing genotypes of beans most susceptible to ALS had less diseased pods in ICM than in both MC and MCT, but the less susceptible genotypes, regardless of their growth type, as well as... |

| Mungbean cultivar MGS Esmeralda was developed by Asian Vegetable Research and Development Center (Shanhua, Taiwan), as a result of crossing between the lines VC 1973A and VC 2768A. In ten trials conducted in the State of Minas Gerais, Brazil, it produced 13.5% more grains than 'Ouro Verde MG-2' (control cultivar), and its highest yield was 2,550 kg ha-1. The cultivar MGS Esmeralda is more susceptible to lodging, and its pods mature more uniformly than Ouro Verde MG-2 pods. One hundred-seed mass of 'MGS Esmeralda' ranged between 5.5 and 6.8 g. Both cultivars are susceptible to powdery mildew and cercospora leaf spot. |

| RAPD-PCR molecular markers were used to identify common bean and soybean hybrid plants derived from crosses between closely related progenitors, with no apparent phenotypic differences. Primers OP-F12 and OP-0O3 were used to identify true hybrids derived from crosses between common bean cultivars Rudá (A 285) and AN 910408, and soybean cultivars Cristalina and Bossier, respectively. Each primer generated one polymorphic DNA band which was present in the male progenitor and absent in the female progenitor. As RAPD bands are normally inherited as dominant characters, the presence of these bands in the F1 plants confirmed their status. |

| Foram conduzidos três ensaios em município de Minas Gerais, com inverno ameno, para estudar a viabilidade do cultivo do feijão-arroz no outono-inverno. Os ensaios foram instalados em Leopoldina, nestas datas: 3 de maio de 1996, 18 de abril de 1997 e 11 de maio de 1998. Foram usados 12 genótipos de feijão-arroz; uma cultivar de feijão-comum foi usada para comparação. Foi empregado o delineamento em blocos ao acaso, com 4 repetições. As plantas foram irrigadas por aspersão, e o controle de pragas com inseticida foi feito quando necessário. Os ciclos de vida do feijão-arroz variaram de 99 a 111 dias (da emergência à colheita), enquanto os do feijão-comum variaram em torno de 90 dias. Não foi observada doença na folhagem do feijão-arroz. As produtividades... |
