We conducted a 5 x 5 complete diallel cross experiment in bread wheat (Triticum aestivum) with the genotypes 6309, Chkwal-50, Dhrabi, Bhkhar-02, and FS-08. Our objective was to evaluate the type of gene action and the general and specific combining abilities required for various morphological traits in wheat. The results of analysis of variance revealed highly significant ... more
The objective of this study was to investigate, using path analysis, the genotypic correlations of primary and secondary production components as well as their decomposition into direct and indirect effects on the yield of coffee crops subjected to programed cycle pruning (PCP). Twenty-two Conilon coffe genotypes belonging to the breeding program developed by ... more
Genetic diversity in nutritional parameters in response to drought of Coffea canephora cultivated in Rondonia state, Brazil
Coffea canephora shows considerable variability for several agronomic traits, including nutritional efficiency. Beside the intrinsic nutritional efficiency of a genotype, the availability of water in the soil is another factor that can cause different responses, which suggests the possibility of selection of genotypes to enhance the nutritional efficiency ... more
Banana is an importment international economical crop, but drought is the most significant environmental stress in banana intrustry. Previous studies on banana drought tolerance evaluated just a few indicators, such as malondialdehyde (MDA) and plasma membrane permeability (PMP), with little or no systematic morphological and physiological information. We examined ... more
Dynamics of expression between onion line traits on the basis of phenotypic and genotypic correlations
The cultivation of onion in Brazil has a relevant socioeconomic contribution. Despite the potential, there are few onion breeding programs for tropical conditions. One of the major obstacles is related to the complexity during the selection steps, since in onion, quantitative characters and low heritability predominate. For this reason, the purpose of this study ... more
Brazil has a great diversity of Capsicum peppers that can be used in breeding programs. The objective of this study was to evaluate genetic variation in traits related to the physiological quality of seeds of Capsicum annuum L. in a segregating F2 population and its parents. A total of 250 seeds produced by selfing in the F1 generation resulting ... more
Transferability of microsatellite markers of Capsicum annuum L. to C. frutescens L. and C. chinense Jacq.
In order to support further genetic, diversity, and phylogeny studies of Capsicum species, the transferability of a Capsicum annuum L. simple sequence repeat (SSR) microsatellite set was analyzed for C. frutescens L. (“malagueta” and “tabasco” peppers) and C. chinense Jacq. (smell peppers, among other types). A total of 185 SSR primers were evaluated ... more
Tolerant varieties can effectively control post-harvest physiological deterioration (PPD) of cassava, although knowledge on the genetic variability and inheritance of this trait is needed. The objective of this study was to estimate genetic parameters and identify sources of tolerance to PPD and their stability in cassava accessions. Roots from 418 cassava accessions, grown in four ... more
Determination of the optimal number of markers and individuals in a training population necessary for maximum prediction accuracy in F2 populations by using genomic selection models
Genomic selection is a useful technique to assist breeders in selecting the best genotypes accurately. Phenotypic selection in the F2 generation presents with low accuracy as each genotype is represented by one individual; thus, genomic selection can increase selection accuracy at this stage of the breeding program. This ... more
Comparative analysis of shell color variety and genetic structure among five high-quality freshwater pearl mussel populations.
Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were ... more
