1. 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

2. Diallel analysis and inbreeding depression in agronomic and technological traits of cotton genotypes
ABSTRACT Cotton provides about 90% of the world textile fiber, and is one of the crops of greater industrial relevance. The objectives of this study were to estimate the inbreeding depressionand the genetic effects involved in the control of the agronomic andfiber quality traits in F1 and F2 generations and to identify promising hybrids for obtaining superio

3. Inheritance of harvest index in common bean
Abstract The aim of this study was to verify if the harvest index (HI) of common bean is higher in modern lines, to verify if its estimate varies with the cycle of the plant and environmental conditions, and to obtain information concerning its genetic control (through diallel crossing). For this purpose, six lines were crossed in a diallel. Evaluations were

4. Performance and carcass traits in the diallel crossing of pacu and tambaqui
With the purpose of evaluating the changes and the degree of heterosis on performance and carcass traits of fish from the diallel crossing between Pacu and Tambaqui, four genetic groups were generated through hormonal induction: pacu, tambaqui, tambacu and paqui. For 196 days, 400 juveniles of each genetic group were stocked in a pond divided into four parts

6. Heterosis performance in industrial and yield components of sweet corn.
Heterosis and its components were evaluated in a diallel crossing system of sweet corn. In the 38 treatments, eigth parents, 28 hybrids and two controls were used, arranged in a randomized block design with three replications.The diallel analysis followed the methodology of Gardner and Eberhart (1966). The following traits were evaluated: male and female flo

7. Controle genético e tolerância ao estresse de calor em populações híbridas e em cultivares de trigo.
O objetivo deste trabalho foi obter informações sobre o controle genético da produtividade de grãos de trigo sob condições de estresse de calor, o grau de tolerância ao estresse de calor de algumas cultivares e linhagens e a identificação de populações segregantes promissoras para a obtenção de linhagens adaptadas às condições da região cent

8. Capacidade de combinação em sete populações de melancia.
Este trabalho teve como objetivo estimar as capacidades geral (CGC) e específica (CEC) de combinação e os efeitos recíprocos (ER) em relação à precocidade, componentes de produção e características do fruto em sete populações de melancia. As populações foram intercruzadas em dialelo, incluindo os recíprocos. Todas as variáveis avaliadas, com

9. Proposta para ampliação da base genética por meio de cruzamento interespecífico no pré-melhoramento do tomateiro / Proposal for amplification the genetic base for interespecific cross in tomato pre-breeding.
The aim of this study was to evaluate: 1 - the variability among families resistant PepYMV from the crossing between S.lycopersicum and S.habrochaites; 2 - the contribution of variability in this cross for the breeding of tomato. The diversity assessment was performed with a square lattice design experiment with two replications and three plants per plot. Th

10. Desempenho de populações segregantes de algodoeiro obtidas por três métodos de hibridação
CHAPTER I - The objectives of this research were to make predictions on segregant populations performance on upland cotton as for selection, using the method proposed by Jinks and Pooni (1976), as well as to identify amongst three different crossing methods, which will originate the most promising population for selection purposes. The present work was condu

12. Heterose entre linhagens de soja quanto aos teores de proteína e de óleo no grão / Heterosis among inbred lines of soybean based on the grain protein and oil contents
The soybean (Glycine max (L.) Merrill) is one of the most important grain cultivated in the world, mainly because its high levels of grain protein and oil, and also due to its high yield. Soybean protein has become an important product in the food and feed industries, due to its nutritional value and technological properties. Agricultural business increasing
