1. Genetic variability in peppers accessions based on morphological, biochemical and molecular traits
ABSTRACT The evaluation of genetic diversity among the accessions of a germplasm collection results in information about promising materials suitable for breeding programs. Thus, the goal of this work was to characterize Capsicum baccatum accessions from different Brazilian regions, based on morphological, biochemical and molecular traits, aiming to support

2. Genotyping and molecular analysis of transgenic sequences in chrysanthemum (Chrysanthemum X morifolium Ramat)
Abstract Genotypes of the chrysanthemum cultivars Harman and Indianapolis were transformed using Agrobacterium tumefaciens strain LBA4404, which carries the binary plasmid pBIN19::Rd29A::ScTPS1TPS2::nos and pBIN19::35S::ScTPS1TPS2::nos, respectively. ISSR markers were used to discriminate two cultivars from each other, and independent transgenic plants gener

3. Population Structure and Genetic Diversity of Sweet Cassava Accessions from the Midwestern, Southeastern and Southern Regions of Brazil
Abstract The objective of this work was to screen sweet cassava accessions collected in smallholding areas in the Midwestern, Southeastern and Southern regions of Brazil, using 15 SSR molecular markers, to determine population structure and genetic diversity. Polymorphism was detected in every loci analyzed, with mean of 6.33 alleles per locus, and mean poly

5. GENETIC DIVERSITY AMONG AND WITHIN BRAVE BEAN (Capparis flexuosa L.) POPULATIONS ASSESSED USING RAPD MARKERS
RESUMO O feijão-bravo (Capparis flexuosa) é uma espécie nativa da Caatinga e é utilizada como forrageira, principalmente na estação seca onde parte das espécies vegetais perdem suas folhas. Objetivou-se estudar a diversidade genética dentro e entre populações de feijão-bravo usando marcadores RAPD. O estudo foi realizado no Laboratório de Biotecn

6. SSR-based genetic analysis of sweet corn inbred lines using artificial neural networks
Abstract Studies on genetic diversity and population structure provide basic information at the molecular level, which is a key input for breeding programs of crop species. This study evaluated the genetic diversity of 12 elite lines of sweet corn, using 20 microsatellite markers. To determine the genetic differentiation among lines, we used an artificial ne

7. A comparison of efficiency parameters of SSR markers and genetic diversity analysis in Amorphophallus paeoniifolius (Dennst.) Nicolson
ABSTRACT Amorphophallus (elephant foot yam) is an herbaceous edible aroid crop which belongs to the family Araceae. The study was undertaken to identify the efficient SSR primer that could differentiate a set of 12 elephant foot yam genotypes. Various efficiency parameters, namely, Polymorphism Information Content (PIC), Marker Index (MI), Resolving Power (R

8. Evaluation of Genetic Diversity amongthe Pakistani Wheat (Triticumaestivum L.) Lines through Random Molecular Markers
ABSTRACT The presence of geneticdiversity is of great importance in improving wheat traits and developing strategies for optimal conservation of germplasm. Genetic diversity was assessed among common wheat cultivars using RAPD (Random Amplified Polymorphic DNA) markers at the Center of Agriculture, Biochemistry and Biotechnology (CABB), University of Agricul

9. Assessment of genetic diversity in Brazilian barley using SSR markers
Abstract Barley is a major cereal grown widely and used in several food products, beverage production and animal fodder. Genetic diversity is a key component in breeding programs. We have analyzed the genetic diversity of barley accessions using microsatellite markers. The accessions were composed of wild and domesticated barley representing genotypes from s

10. Genetic diversity assessed by microsatellite markers in sweet corn cultivars
Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H) was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in te

11. Developing a common bean core collection suitable for association mapping studies
Because of the continuous introduction of germplasm from abroad, some collections have a high number of accessions, making it difficult to explore the genetic variability present in a germplasm bank for conservation and breeding purposes. Therefore, the aim of this study was to quantify and analyze the structure of genetic variability among 500 common bean a

12. Development and validation of new SSR markers from expressed regions in the garlic genome
Only a limited number of simple sequence repeat (SSR) markers is available for the genome of garlic (Allium sativum L.) despite the fact that SSR markers have become one of the most preferred DNA marker systems. To develop new SSR markers for the garlic genome, garlic expressed sequence tags (ESTs) at the publicly available GarlicEST database were screened f
