1. Bayesian analysis of growth, stem straightness and branching quality in full-sib families of Eucalyptus globulus
ABSTRACT Eucalyptus globulus is one of the most commonly planted hardwood species for industrial use in various temperate regions around the world. The present study aimed to evaluate 62 full-sib families of E. globulus in one of the southernmost progeny trials of the species in the south of Chile. Estimates of genetic parameters for stem straightness, branc

2. Effective population size and genetic gain expected in a population of Coffea canephora
Abstract This work aimed to study the effective population size and genetic gain in a population of robusta coffee (Coffea canephora Pierre) and verify the possibility of using recurrent selection. The experiment comprised 25 treatments, consisting of 21 C. canephora progenies and four C. arabica (cultivars) grown in Brazil. The experimental design was a 5x5

3. Inheritance of resistance to Fusarium ear rot in popcorn
Abstract To date, no studies on the inheritance of Fusarium spp. ear rot resistance in popcorn are available. The purpose of this paper was to investigate the additive-dominance model to estimate the genetic components of variance, heritability and the inheritance pattern in a diallel for popcorn, by Hayman’s approach. The experiment was carried out in two

4. Generation mean analysis of root growth under aluminium-stress hydroponics in the soybeans (Glycine max (L.) Merrill).
There are vast areas in the tropics which are limited in their use by mineral stresses such as aluminium and low available nutrients. The grain crops shall be further adapted if breeding programmes include identification and use of the genetic factors to these hindrances. Three soybean families originated from crosses, selfing and backcrosses among the varie

5. Relationship between epistasis and aggressiveness in resistance of pepper (Capsicum annuum L.) to Phytophthora nicotianae
This study evaluated the types of gene action governing the inheritance of resistance to Phytophthora nicotianae necrosis in populations derived from two crosses involving two susceptible (Beldi and Nabeul II) and one resistant (CM334) cultivars of pepper (Capsicum annuum L.). Populations, composed of Pr, Ps, F1,F2,BC1Pr, and BC1Ps generations, were inoculat

6. Epistasis and genotype-by-environment interaction of grain protein content in durum wheat
Parental, F1, F2, BC1 and BC2 generations of four crosses involving four cultivars of durum wheat (Triticum durum Desf.) were evaluated at two sites in Tunisia. A three-parameter model was found inadequate for all cases except crosses Chili x Cocorit 71 at site Sidi Thabet and Inrat 69 x Karim at both sites. In most cases a digenic epistatic model was suffic

7. Skew normal mixed models in microarray data generated from complex pedigrees / Modelos mistos normais assimÃtricos em dados de microarrays originados de pedigrees complexos / Modelos mistos normais assimÃtricos em dados de microarrays originados de pedigrees complexos / Skew normal mixed models in microarray data generated from complex pedigrees
Estimates of heritability for gene expression are scarce and commonly originated from family structures, in which the variability of responses among and within families are provided under a uniform covariance structure for related individuals, ignoring the known relationship among all individuals in the pedigree. Gauss-Markov normal mixed models are the usua

8. Herança da produção de grãos e dos componentes de produção em soja / Inheritance of grain production and yield components in soybean
The knowledge of inheritance of traits is very important for breeding purposes. However, the inheritance is highly influenced by the environment and the genotypic composition of the population and thus, the accumulative information of estimates is very important for a better knowledge of the inheritance of quantitative traits. Most of the studies of inherita

9. Controle do desenvolvimento vegetal pela interação auxina-citocinina. Uma nova abordagem baseada no estudo de mutantes de tomateiro (Solanun lycopersicum cv Micro-Tom) / Control of plant development by auxin-cytokinin interactions. A new approach based on tomato (Solanum lycopersicum cv Micro-Tom) mutants.
The plant hormones auxin and cytokinin are crucial for plant development, since they control cell division, expansion and differentiation, which regulate developmental processes starting from embryo formation to fruit ripening and senescence. Auxins and cytokinins usually regulate the same physiological responses, suggesting multiple mechanisms of interactio

10. Developmental genetic analysis of fruit shape traits under different environmental conditions in sponge gourd (Luffa cylindrical (L) Roem. Violales, Cucurbitaceae)
Analysis of genetic main effects and genotype × environment (GE) interaction effects for the fruit shape traits fruit length and fruit circumference in the sponge gourd (Luffa cylindrical (L) Roem. Violales, Cucurbitaceae) was conducted for diallel cross data from two planting seasons. A genetic model including fruit direct effects and maternal effects and

11. Diffraction and an infrared finite gluon propagator
We discuss some phenomenological applications of an infrared finite gluon propagator characterized by a dynamically generated gluon mass. In particular we compute the effect of the dynamical gluon mass on pp and ${\bar{p}}p$ diffractive scattering. We also show how the data on gammap photoproduction and hadronic gg reactions can be d

12. Generation mean analysis for quantitative traits in sesame (Sesamum indicum L.) crosses
To study the nature and magnitude of gene effects for yield and its components in sesame (Sesamum indicum L.) we carried out generation mean analysis using the following four crosses of different sesame cultivars: VS 9510 x Co1; NIC 7907 x TMV 3; Cianno 13/10x VRI 1; and Si 1115/1 x TMV 3. The P1, P2, F1, F2, BC1 and BC2 of these generations were studied for
