2. Two independent grain-length mutants mapped to a single region on the long arm of chromosome 2 in rice
ABSTRACT Grain shape in rice is a key determinant of grain appearance, yield and market value, and thus has been widely studied. Rice mutant lines with long-grain phenotypes were previously isolated from an M2 population derived from mutagenized mature pollen grains that were treated with gamma-ray irradiation for a cultivar Ma85. To understand the genetic b

3. Diversidade em Psidium guajava L. por caracteres morfológicos, moleculares e citogenéticos / Diversity in Psidium guajava L. by morphological, molecular and cytogenetics
Guava (Psidium guajava L.) is one of the most economically important fruit crop from Myrtaceae family. Brazil is one of the largest producers of guava in the world, which is a potential crop in growth and profitability. Cross-pollination of the species and the existence of heterogeneous seminal propagation orchards result in variability, allowing the selecti

5. Métodos estatísticos na seleção genômica ampla para curvas de crescimento em animais / Statistical methods used in genome wide selection for growth curves in animals
O principal atrativo da genética molecular em benefício do melhoramento genético aplicado é a utilização direta das informações do DNA na seleção genômica, de modo a permitir alta eficiência seletiva, rapidez na obtenção de ganhos genéticos com a seleção e baixo custo. Uma forma prática e consistente de analisar a eficiência produtiva de a

6. Genetic diversity of Brazilian triticales evaluated with genomic wheat microsatellites
The objective of this work was to determine the genetic variability available for triticale (X Triticosecale Wittmack) crop improvement in Brazil. Forty-two wheat genomic microsatellites were used to estimate the molecular diversity of 54 genotypes, which constitute the base of one of the major triticale breeding programs in the country. Average heterozygosi

7. Genetic characterization of the Moxotó goat breed using RAPD markers.
The objective of this study was to verify the genetic diversity between and within seven populations of Moxotó goat (n = 264) from the States of Pernambuco, Paraíba and Rio Grande do Norte, using RAPD (Random Amplified Polymorphic DNA). Moxotó, as well as other naturalized breeds, suffers genetic losses due to the indiscriminate miscegenation with breeds

8. Molecular characterization and genetic structure of the Nero Siciliano pig breed
Nero Siciliano is an autochthonous pig breed that is reared mainly in semi-extensive systems in northeastern Sicily. Despite its economic importance and well-appreciated meat products, this breed is currently endangered. Consequently, an analysis of intra-breed variability is a fundamental step in preserving this genetic resource and its breeding system. In

9. Genetic variation in the Solanaceae fruit bearing species lulo and tree tomato revealed by Conserved Ortholog (COSII) markers
The Lulo or naranjilla (Solanum quitoense Lam.) and the tree tomato or tamarillo (Solanum betaceum Cav. Sendt.) are both Andean tropical fruit species with high nutritional value and the potential for becoming premium products in local and export markets. Herein, we present a report on the genetic characterization of 62 accessions of lulos (n = 32) and tree

10. Caracterização da diversidade genética de Teca (Tectona grandis) de diferentes procedências usando marcadores microssatélites / Characterization of genetic diversity of teak (Tectona grandis) from different provenances using microsatelliate markes
Teak (Tectona grandis) is one of the main timber species in the world with high economic value, famous for its beauty, strength and durability. The species occurs naturally in India, Myanmar, Thailand, Laos and Indonesia, where diversity studies have been conducted with regard to the conservation of genetic resources. However, there is a need for studies of

11. GENETIC VARIABILITY OF PHYSIC NUT (JATROPHA CURCAS L.) CULTIVATED IN TWO AGROECOSYSTEM IN SERGIPE. / VARIABILIDADE GENÉTICA DE PINHÃO MANSO CULTIVADO EM DOIS AGROECOSSISTEMAS DE SERGIPE.
Jatropha curcas L. (Euphorbiaceae) has attracted considerable interest in recent years because of its high potential to provide oil for the production of biofuel. This interest has resulted in increased investments in the cultivation of J. curcas in many areas all over the world. However, J.curcas remains an un-domesticated crop and there is a lack of scient
