1. Mapping of QTL for total spikelet number per spike on chromosome 2D in wheat using a high-density genetic map
Abstract Total spikelet number per spike (TSS) is one of the key components of grain yield in wheat. Chromosome (chr.) 2D contains numerous genes that control TSS. In this study, we evaluated 138 F8 recombinant inbred lines (RILs) derived from an F2 population of a synthetic hexaploid wheat line (SHW-L1) and a common wheat cultivar (Chuanmai 32) for TSS in s

3. Association of candidate genes for fatty acid content in soybean by temperature-switch PCR (TSP) genotyping
Abstract The development of molecular markers is essential for improvement of soybean cultivars with modified fatty acid content. The objective of this study was to identify and validate SNP markers in candidate genes for fatty acid content in soybean. Six candidate genes (ARAF, PDAT, ABI3, FAD2-1b, FAD3B, and FAD3C) were selected. Alignment of gene sequence

4. Papaya recombinant inbred lines selection by image-based phenotyping
ABSTRACT: The selection of superior Carica papaya (L) genotypes depends on the availability of genetic variability and on the favorable and simultaneous response of the genotypes to those traits of most interest. However, manual phenotyping (MP) demands intensive labor, is time-consuming and expensive. The aim of the current study is to access the efficiency

5. Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Abstract Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 reco

6. Genética molecular de caracteres cuantitativos en cruzamientos dialélicos de tomate
The purpose of this research was to evaluate molecular markers and some quantitative fruit traits, in a complete diallel cross without reciprocals, among five tomato recombinant inbred lines and their hybrids. Amplified fragment length polymorphism (AFLP) and pericarp polypeptide profiles were obtained in four stages of fruit maturity of 15 genotypes. Among

7. Analysis of preharvest sprouting in three Brazilian wheat populations.
The objective of this work was to evaluate the possibility of obtaining recombinant inbred wheat lines more resistant to preharvest sprouting, independently of colour genes, in three red-grained Brazilian wheat populations. The results showed statistical significance among lines within all populations, which presented a normal distribution and transgressive

9. Inheritance of resistance to soybean cyst nematode races 3 and 14 in soybean RIL and F2 populations
The objective of this work was to evaluate the soybean inheritance of resistance to cyst nematode races 3 and 14. The following populations where evaluated: one population of recombinant inbred lines (RILs) [Hartwig (resistant) x Y23 (susceptible line)] for races 3, 14 and 9; one population of families F2:3 [M-SOY 8001 (resistant) x MB/BR 46 - Conquista (sus

10. Identification of quantitative trait loci for resistance against soybean sudden death syndrome caused by Fusarium tucumaniae.
The objective of this work was to identify genomic regions that underlie resistance to Fusarium tucumaniae sp. nov., the causing agent of sudden death syndrome (SDS) in soybean in South America, using a population with a genetic background different from that previously reported for Fusarium virguliforme sp. nov. (F. solani f. sp. glycines), also responsible

12. Caracterização fenotípica e genotípica de caracteres agronômicos em uma população de linhagens recombinantes de aveia / Phenotypic and genotypic characterization agronomic traits in a population of recombinant inbred lines of oats (Avena sativa L.)
O melhoramento genético de aveia envolve a seleção de múltiplos caracteres quantitativos e qualitativos. O conhecimento das regiões genômicas que afetam estas características possibilita a seleção assistida por marcadores moleculares, técnica que visa complementar a seleção convencional. Sendo assim, o objetivo deste trabalho foi de identificar r
