1. Resistance of cocoa to Moniliophthora perniciosa – progenitors and progenies selection
ABSTRACT Witches' broom, caused by Moniliophthora perniciosa, is the most important cacao disease in Brazil, and the final objective of this study is increasing the level and durability of resistance to this fungus, through the association of different alleles or genes favorable to the character, for the generation of new cocoa varieties. It was conducted, f

2. Combining abilities analysis for ear rot resistance in popcorn hybrids development
ABSTRACT Ear rot caused by fungi of genus Fusarium (FER) is one of the potentially harmful diseases to grain quality in maize. Given the capacity to produce mycotoxins, FER presents a risk to food safety. This study sought to identify parents and indicate hybrids of popcorn with a higher level of resistance to the incidence and severity of FER. Hybrids were

3. The usefulness of GGE biplot methodology for line × tester data of maize inbred lines
ABSTRACT The genotype + genotype × environment (GGE) biplot methodology has the potential to determine combining ability effects, identify efficient testers, and distinct heterotic groups in a line × tester study. However, it has not been adequately applied for such analysis. Therefore, this study was done to assess the combining ability of some maize inbr

4. Identification of populations and hybrid combinations of maize for in natura consumption
ABSTRACT Brazil is one of the leading countries in the production of maize (Zea mays), with great potential for growing green maize, which has a superior commercial value in relation to maize marketed in the form of grains. Although important, the availability of cultivars recommended for the production of green maizeis still very scarce. The objectives of t

5. Partial diallel and potential of super sweet corn inbred lines bt 2 to obtain hybrids
RESUMO Os objetivos foram determinar o potencial de linhagens S4 de milho superdoce para síntese de híbridos, identificar os tipos de ações gênicas predominantes e as correlações para diferentes caracteres importantes para o melhoramento. Os 81 híbridos obtidos em um dialelo parcial 9x9 e três testemunhas foram avaliados em blocos completos casualiz

6. Combining capacity and heterosis in eggplant hybrids under high temperatures
RESUMO Este trabalho teve como objetivo estimar a capacidade combinatória e a heterose de híbridos de berinjela em condições de altas temperaturas. Foram avaliados sete genitores, doze combinações híbridas oriundas de um dialelo parcial e o híbrido Ciça F1 como testemunha. O experimento foi conduzido em casa de vegetação, no delineamento experimen

7. Selection of parents for low nitrogen stress through the combining ability of maize partially inbred lines
ABSTRACT. The objective of this work was to estimate the general combining ability of partially inbred lines under high and low nitrogen (N) conditions and to select promising lines to obtain high yields for both conditions. Fifty-five partially inbred S1 progenies were evaluated using the top-cross method, where the lines were crossed with two testers. The

8. Estimation of genetic merit of diallel hybrids of sweet pepper by mixed models
RESUMO: A utilização de modelos mistos na avaliação de cruzamentos dialélicos é uma opção altamente oportuna para a fidedigna predição dos valores genéticos das progênies. Na cultura do pimentão, os híbridos são largamente explorados comercialmente, principalmente por suas características de importância econômica. O objetivo deste trabalho

10. Selection of squash “Menina Brasileira” carrying the allele “Bush” with high yield potential
RESUMO Objetivou-se introduzir o alelo Bush, de cultivares com hábito de crescimento tipo “moita”, em acessos de Cucurbita moschata e selecionar os melhores cruzamentos quanto ao potencial produtivo e ao formato de fruto padrão “menina brasileira” por meio da capacidade geral (CGC) e da capacidade específica (CEC) de combinação. Para determinar

11. A new partial diallel model adapted to analyze reciprocal effects in grain yield of maize
Abstract Comparison between two distinct groups using a partial diallel and considering reciprocal effects has not been described in the scientific literature, limiting diallel analysis results. This study compared two groups of parents using a partial diallel, and analyzed the general and specific combining ability and reciprocal effects, divided into mater

12. Genetic control of aluminum tolerance in tropical maize germplasm
ABSTRACT Aluminum (Al) toxicity is the most limiting factor to maize crop productivity in acid soils. Therefore, the understanding of inheritance of Al tolerance in maize is important for the developmentof more adequate procedures for Al tolerant genotypes selection. In this sense, the objectives of this study were to determine the inheritance, and the gener
