1. Resistance of the wild tomato Solanum habrochaites to Phytophthora infestans is governed by a major gene and polygenes
Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor. F1 plant

2. Clonal Arabica coffee resistant to Meloidogyne paranaensis and damage threshold on plants development
ABSTRACT: Plants of Coffea arabica Icatu IAC 925 germplasm show resistance to Meloidogyne paranaensis under field conditions, but with variable rates of segregation. One mother plant, IAC 3, of Icatu IAC 925 was evaluated under controlled conditions through the reaction of its clones, obtained by somatic embryogenesis. Reproduction of nematodes in clones wer

3. Genetic diversity assessed by microsatellite markers in sweet corn cultivars
Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H) was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in te

5. Selecao massal estratificada em girassol em diferentes condicoes ambientais.
Uma cultivar de polinizacao aberta de girassol (Helianthus annuus L.) foi submetida a selecao massal estratificada, em duas epocas de semeadura sucessivas, com o objetivo principal de avaliar o progresso genetico obtido com a realizacao de dois ciclos de selecao por ano agricola, incluindo um ciclo em condicoes de estresse. A selecao foi realizada apenas no

6. Gene flow from transgenic common beans expressing the bar gene.
Gene flow is a common phenomenon even in self-pollinated plant species. With the advent of genetically modified plants this subject has become of the utmost importance due to the need for controlling the spread of transgenes. This study was conducted to determine the occurrence and intensity of outcrossing in transgenic common beans. In order to evaluate the

7. Abelhas visitantes florais e potenciais polinizadoras do cafà (Coffea arabica L.) ecolÃgico e sombreado no MaciÃo de Baturità - Cearà / Bees flower visitors and potential pollinators of coffee (Coffea arabica L.) ecological and shadow Baturità Massif â CearÃ
The survey was conducted on the farm SÃo SebastiÃo, located in the city of Mulungu - CE. Data were collected and studied during the period November 2009 to June 2010 with the aim of studying the floral visitors and pollination of coffee (Coffea arabica L.) and green shade of Mundo Novo and Maragogipe. We studied the floral biology and pollination requireme

9. Recurrent selection in potato for heat tolerance. / SeleÃÃo recorrente em batata visando a tolerÃncia ao calor
All potato cultivars most planted in Brazil come from temperate countries. They are not adapted to the tropical conditions and this results in poorer tuber yields. The objective of this research was to study how recurrent selection can contribute to the development of more adapted potato clones to the tropical climate. The base population (SR0) used in this

10. Organic production of cherry tomatoes: cultivar comparison, plant densities and pruning regimes. / Produção orgânica de tomateiro tipo "cereja": comparação entre cultivares, espaçamentos e sistemas de condução da cultura
Tomato plants are highly susceptible to a great number of pests and diseases . This is a constraint to organic production, especially under field conditions. New technologies should be developed to improve organic tomato yields and reduce disease incidence. Row spacing and pruning regimes are two aspects which may be targeted to achieve these goals. Since ch

11. Genetic analysis of adult-plant resistance to leaf rust in a double haploid wheat (Triticum aestivum L. em Thell) population
A genetic analysis of adult plant resistance to leaf rust (Puccinia triticina) was performed in in vitro obtained double haploid progenies from a cross between the Brazilian wheat cultivar Trigo BR 35, which, under the high inoculum pressure of the southern region, has been resistant to leaf rust for more than 12 years, and the susceptible cultivar IAC 13-Lo

12. The Effect on Net Photosynthesis of Pedigree Selection for Low and High Rates of Photorespiration in Tobacco
A normal appearing plant with a low rate of photorespiration (ratio of 14CO2 released light/dark = 1.6) was found in an unselected tobacco (Nicotiana tabacum) cultivar. The plant was self-pollinated, and further selections were made on several successive generations. Excised leaves from the progeny of the selections were examined for photorespiration and net
