“…Essential-oil content (EOCP) was lower in seeds harvested from the second planting date, whereas FAC was higher. Differences between phenological, morphological, and chemical traits due to years and planting dates in this study demonstrate the effect of the environment on the expression of many of these phenotypic traits (Lombard et al 2001;Nuel et al 2001). It confirms the capacity of the plants to modify trait expression, as a consequence of environmental changes; this phenomenon is called phenotypic plasticity (DeWitt and Scheiner 2004).…”

“…On the basis of 80 informative markers greater than 70 base pairs in length with polymorphism information content (PIC) values greater than 0.15, determined by using Logiciel de Calcul de Distances Molécul-aires entre Variétés (LCDMV) software (Lombard et al 2001;Dubreuil et al 2003), we computed Modified Rogers' distances for accessions under study, and a genetic distance matrix was then constructed by using Tools for Population Genetic Analyses Software (TFPGA) version 1.3 2000 (Miller 1997). Modified Rogers' distance is a Euclidean distance measure that considers each scored locus as an orthogonal dimension.…”

“…However, they can also have serious limitations. Many are controlled by multiple alleles and loci, making it difficult to relate patterns of phenotypic variation to their genetic bases, and their expression may be strongly affected by the environment (Lombard et al 2001;Nuel et al 2001). Still, most investigations of variation within and among coriander populations have been based on morphological traits, although many of those traits are environmentally influenced, and genotype-byenvironment interactions are common (Jindla et al 1985;Sastri et al 1989;Bhandari and Gupta 1991;Angelini et al 1997;Ali et al 1999).…”

Our goals for this research were to elucidate phenotypic and biochemical diversity in coriander (Coriandrum sativum L.) populations maintained at the North Central Regional Plant Introduction Station in Ames, IA, and examine relationships between amplified fragment length polymorphism (AFLP) markers and patterns of phenotypic and biochemical diversity. Phenotypic and biochemical traits were evaluated, and analyses of variance and mean comparisons were performed on the resulting data sets. Euclidean distances from phenotypic (PD) and biochemical (BD) data were estimated, and modified Rogers' distances (RD) were estimated for 80 polymorphic AFLP markers. These data were subjected to cluster analyses (CA) and principal components analyses (PCA), to reveal patterns among populations, and to analyses of molecular variance (AMOVA) for grouping patterns from PD and BD by using the 80 polymorphic AFLP markers. Resulting phenotypic, biochemical, and molecular distance matrices were also compared by applying Mantel tests. Our results describe significant differences among populations for all the phenotypic traits, and dendrograms obtained from PD and BD revealed complex phenetic patterns, as did groups from PCA. The primary seed essential oils and nearly all fatty-acid components were identified and their abundance measured; the primary chemical constituents of corresponding PCA groups are described herein. Molecular evidence supported phenotypic and biochemical subgroups. However, variation attributed among subgroups and groups was very low (∼4-6%), while variation among populations within groups was intermediate (∼24-26%), and that within populations was large (∼69-70%), reflecting weak differentiation among subgroups and groups, which was confirmed by values for fixation indices. Phenotypic subgroups described in this study differed somewhat from previous infraspecific classifications. Weak correlations were found between the phenotypic and biochemical matrices and between the biochemical and AFLP matrices. No correlation was found between the phenotypic and AFLP matrices. These results may be related to coriander's phenotypic plasticity, its wide range in lifecycle duration, its predominantly allogamous reproductive biology, a human-selection process focused on special traits that may be controlled by few genes, and the widespread trade of coriander seeds as a spice, which may result in dynamic, poorly differentiated molecular variation, even when phenotypic and biochemical differentiation is easily documented.

“…For instance, as previously reported by Afiah and Abdel-Hakim (1999) and Saker et al (2005) Virk et al (2000). In this context, Lombard (2001) concluded that molecular markers can be used as a tool and a convenient method for application of combine information from a large number of markers. Herein, we could conclude that it is possible to tag the breeding history and the origin of different barley genotypes using a combination of different molecular systems.…”

Haemoglobin polymorphism, haemoglobin concentration, blood group and genotypes of wild and cultured Clarias gariepinus were investigated. Blood samples of Clarias gariepinus collected from Lake Alau (wild) and Dalori fish farm (cultured) were subjected to cellulose acetate electrophoresis to reveal the activities of hemoglobin (Hb). The result shows that both wild and cultured C. gariepinus had AA, BB and CC genotypes in the males and females. However, BD genotype was observed only in the female wild C. gariepinus. The percentage AA and BB genotypes of wild male C. gariepinus was 6.6% each. Wild females had AA, BB, CC and BD genotype with frequencies of 26.6, 33.3, 20 and 6.6% respectively. Cultured male C. gariepinus had AA, BB and CC with frequencies of 13.3, 26.6 and 6.6%, respectively, while the female C. gariepinus had AA, BB and CC with frequencies of 20, 13.3 and 20% respectively. Wild C. gariepinus had the highest (10.36 g/dl) haemoglobin
