Body structure; Frame scores; Genetic improvement; Genetic parameters; Nellore

Models for estimation of frame scores in Nellore beef cattle (FRAME_GMA) were developed, comparing them with frame scores estimated using equations proposed by the Beef Improvement Federation (FRAME_BIF, USA). Correlation among frame scores obtained by these two methodologies, along with the independent variables considered in the estimation models, were also studied. A data set with 12,728 ... more

Allelic interactions; diallel analysis; Epistasis; Genetic improvement; Heterozygosity; Over-dominance

Isabgol is a medicinal plant known for its high-quality dietary fiber. The genetics and inheritance of economic characters, such as number of panicles, panicle length, seed yield, and swelling factor, were measured by diallel analysis of F1 progenies from seven parents. The additive component of genetic variance was significant for days to flowering, plant height, branches/plant, peduncle ... more

Forage; Genetic improvement; Plant resistance

An understanding of the interaction between spittlebugs and forage grasses is essential for establishing factors that favor productive pastures. In the present study, we evaluated the protein profiles of the spittle of Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) fed various elephant grass genotypes. Each plant was infested with a single fifth-instar M. ... more

Genetic improvement; Plant breeding; Selection efficiency

The objective of this study was to compare the BLUP selection method with different selection strategies in F2:4 and assess the efficiency of this method on the early choice of the best common bean (Phaseolus vulgaris) lines. Fifty-one F2:4 progenies were produced from a cross between the CVIII8511 x RP-26 lines. A randomized block design was used with 20 ... more

Genetic improvement; Honeybee queen selection; Major royal jelly proteins; mrjp3; Polymorphism

It is important to select the best honeybees that produce royal jelly to identify important molecular markers, such as major royal jelly proteins (MRJPs), and hence contribute to the development of new breeding strategies to improve the production of this substance. Therefore, this study focused on evaluating the genetic variability of mrjp3, mrjp5, and mrjp8 ... more

Genetic improvement; Multi-diverse analysis; Saccharum

This study evaluated different strategies to select sugar cane families and obtain clones adapted to the conditions of the Brazilian savannah. Specifically, 7 experiments were conducted, with 10 full sib families, and 2 witnesses in common to all experiments, in each experiment. The plants were grown in random blocks, with witnesses in common (incomplete blocks), and 6 repetitions of each ... more

Ear size; quantitative trait locus; Space flight; Zea mays

The development of molecular markers has contributed to progress in identifying the gene(s) responsible for favorable variations in maize studies. In this study, quantitative trait locus (QTL) mapping was conducted using simple sequence repeat markers in an F2 sweet corn population from a cross between parental line 1132 and space flight-induced mutant line 751 to identify the ... more

Full-sibling families; Genetic gains; Selection index; Zea mays

As part of the Universidade Estadual do Norte Fluminense recurrent selection program of popcorn, we evaluated full-sib families of the sixth cycle of recurrent selection and estimated genetic progress for grain yield and expansion capacity. We assessed 200 full-sib families for 10 agronomic traits, in a randomized block design, with two replications within sets in two environments: Campos ... more
