in order to investigate drought stress tolerance and adaptation in 15 iranian endemic coriander (coriandrum sativum l.), three experiments were conducted separately through randomized complete block design whit three replications in field conditions. in experiments, the coriander populations were well watered, stressed at one step and stressed gradually, respectively. in this research, 17 phono...

Quantifying consistent differences in behaviour among individuals is vital to understanding the ecological and evolutionary significance of animal personality. To quantify personality, the phenotypic variation of a behavioural trait is partitioned to assess how it varies among individuals, which is also known as repeatability. If pedigree data are available, the phenotypic variation can then be...

Recent studies in population of European ancestry have shown that 30% ~ 50% of heritability for human complex traits such as height and body mass index, and common diseases such as schizophrenia and rheumatoid arthritis, can be captured by common SNPs and that genetic variation attributed to chromosomes are in proportion to their length. Using genome-wide estimation and partitioning approaches,...

Common wild rice (Oryza rufipogon Griff.) is important to broaden the narrow genetic diversity of cultivated rice. To better understand the genetic variation, heritability and genetic correlations of agronomically important traits, 156 F2:3 families derived from the cross between rice (Oryza sativa) and wide rice (O. rufipogon Griff.) were evaluated under field conditions. The Analysis of Varia...

This is the first comprehensive study of the genetic analysis of the majority of oleoresin components of slash pine (Pinus elliottii). Pine oleoresin, the resin secreted from the pine tree, is a raw material widely used in industrial products. The objective of this study was to explore the genetic variation and correlation between the major oleoresin components of 50 open pollinated families of...

Ninety-two rice (Oryza sativa L.) genotypes were evaluated during kharif 2013 to estimate the genetic variability, heritability and correlation coefficients for 14 physicochemical and cooking quality traits. The experiment was conducted in a complete randomized block design with 3 replications. Highly significant (P < 0.01) differences were observed for all 14 quality characters studied. Among ...

Late-onset Alzheimer's disease (LOAD) can present heterogeneously, with several subtypes recognized, including dysexecutive AD. One way to identify people with dysexecutive AD is to consider the difference between memory and executive functioning, which we refer to as the executive prominent/memory prominent spectrum. We aimed to determine if this spectrum was heritable. We used neuropsychologi...

Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...

DNA methylation has been implicated in a number of diseases and other phenotypes. It is, therefore, of interest to identify and understand the genetic determinants of methylation and epigenomic variation. We investigated the extent to which genetic variation in cis-DNA sequence explains variation in CpG dinucleotide methylation in publicly available data for four brain regions from unrelated in...
