Phenotypic diversity among Croatian common bean (Phaseolus vulgaris L.) landraces was assessed by analysing 12 qualitative and six quantitative traits in 338 accessions collected from all production areas in Croatia. Out of 12 qualitative morphological traits, seed coat colour was the most polymorphic among accessions having the highest Shannon’s information index and discriminating power. Out ...

abstract almond is an important nut tree which is cultivated in many mediterranean countries. this study was carried out to study some vegetative and reproductive traits as well as qualitative and quantitative characteristics and their correlation in some self-compatible and self-incompatible genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent). quantitat...

quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...

We evaluated the genetic variation of cassava accessions based on qualitative (binomial and multicategorical) and quantitative traits (continuous). We characterized 95 accessions obtained from the Cassava Germplasm Bank of Embrapa Mandioca e Fruticultura; we evaluated these accessions for 13 continuous, 10 binary, and 25 multicategorical traits. First, we analyzed the accessions based only on q...

Linkage relationships between loci affecting quantitative traits (QTL) and marker loci were examined in an interspecific cross between Lycopersicon esculentum and Lycopersicon pimpinellifolium. Parental lines differed for six morphological markers and for four electrophoretic markers. Almost 1700 F-2 plants were scored with respect to the genetic markers and also with respect to 18 quantitative...

quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. reports name the acyl coa: diacylglycerol acyltransferase (dgat1) gene as a potential candidate gene with dinucleotide substitution (aa to gc) in exon viii which causes the change of lysine to alanine in amino acid (k232a).the aim of the present study was to estimate the frequency...

MOTIVATION Most biological traits may be correlated with the underlying gene expression patterns that are partially determined by DNA sequence variation. The correlations between gene expressions and quantitative traits are essential for understanding the functions of genes and dissecting gene regulatory networks. RESULTS In the present study, we adopted a novel statistical method, called the...

Grain yield in rice is a complex trait multiplicatively determined by its three component traits: number of panicles, number of grains per panicle, and grain weight; all of which are typical quantitative traits. The developments in genome mapping, sequencing, and functional genomic research have provided powerful tools for investigating the genetic and molecular bases of these quantitative trai...
