Vazov Str., Bulgaria Tel: +359886021598 Email: [email protected] Abstract: In breeding process of forage pea (Pisum sativum L.) inter variety crosses between two Bulgarian: Pleven 4 (spring form) and Pleven 10 (winter form) and two Russian: Rosacrono (spring form) and Shtambovyi (winter form) varieties a...

Genetic variation of 36 Sechium edule accessions collected across 12 states in India was assessed using morphological traits and DAMD markers. Eighteen fruit morphological traits (both qualitative and quantitative) were evaluated to confirm the variations in the present collection. Quantitative traits showed major variations with respect to fruit weight (7.85-498.33 g/fruit), fruit length (5.8-...

Admixture mapping is a popular tool to identify regions of the genome associated with traits in a recently admixed population. Existing methods have been developed primarily for identification of a single locus influencing a dichotomous trait within a case-control study design. We propose a generalized admixture mapping (GLEAM) approach, a flexible and powerful regression method for both quanti...

The availability of robust quantitative biological markers that are correlated with qualitative psychiatric phenotypes can potentially improve the power of linkage methods to detect quantitative-trait loci influencing psychiatric disorders. We apply a variance-component method for joint multipoint linkage analysis of multivariate discrete and continuous traits to the extended pedigree data from...

OBJECTIVE The existing methods for identifying multiple rare variants underlying complex diseases in family samples are underpowered. Therefore, we aim to develop a new set-based method for an association study of dichotomous traits in family samples. METHODS We introduce a framework for testing the association of genetic variants with diseases in family samples based on a generalized linear ...

We have reviewed the available data on VM, the amount of genetic variation in phenotypic traits produced each generation by mutation. We use these data to make several qualitative tests of the mutation-selection balance hypothesis for the maintenance of genetic variance (MSB). To compare VM values, we use three dimensionless quantities: mutational heritability, VM/VE, the mutational coefficient...
