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. 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

4. 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

5. Combining Ability for Resistance to White Mold in a Diallel Cross of Soybean
Abstract The white mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the most important diseases of soybean. The objective of the present work was to evaluate the soybean reaction to the fungus S. sclerotiorum, which causes white mold, in a partial diallel with 50 crosses. The Group I of parents was composed of ten experimental lines with hi

6. Solid dispersion-based pellet for colon delivery of tacrolimus through time- and pH-dependent layer coating: preparation, in vitro and in vivo studies
The intent of the present investigation is to develop and evaluate colon-specific coated tacrolimus solid dispersion pellet (SDP) that retards drug release in the stomach and small intestine but progressively releases in the colon. Tacrolimus-SDP was prepared by extrusion-spheronization technology and optimized by the micromeritic properties including flowab

7. 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

8. 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

9. 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

10. Selection of maize top-crosses for different nitrogen levels through specific combining ability
ABSTRACT An alternative to increase yield without raising the production costs and minimizing the dependence of agricultural inputs is the development of maize genotypes presenting high nitrogen (N) use efficiency under low N level conditions. Thus, the objective of this study was to estimate the specific combining ability of maize top-crosses under high and

11. 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

12. The combining ability of popcorn S7 lines for Puccinia polysora resistance purposes
ABSTRACT The present study resulted from the lack of information on the genotypic expression ruling the resistance to rust and on the main traits of economic importance to the herein addressed crop. The combining ability of 16 popcorn lines and hybrids was assessed in partial diallel cross in two representative locations in Rio de Janeiro State, Brazil, wher
