in order to providing selection indices using heritability and correlation effective traits on yield and multiple regression an experiment was conducted by 265 f3 families as well as parents and f1 related to gharib × khazar population in 2009 at gonbad high education center fields. days to repining (0.97) and panicle number and flag leaf length (0.66) had maximum and minimum heritability, resp...

BACKGROUND AND OBJECTIVES The severity of HIV-1 infection, measured by set-point viral load (SPVL), is highly variable between individuals. Its heritability between infections quantifies the control the pathogen genotype has over disease severity. Heritability estimates vary widely between studies, but differences in methods make comparison difficult. Phylogenetic comparative analysis offers me...

A study was carried out to assess the genetic variability and association among yield attributing traits in 60 different safflower genotypes over six environments. The pooled analysis of variance (ANOVA) revealed that all attributes had a considerable degree variation.The parameters phenotypic coefficients variation (PCV) higher than genotypic (GCV)for characteristics evaluated, indicating expe...

We examine heritability estimation of an ordinal trait for osteoarthritis, using a population of pig-tailed macaques from the Washington National Primate Research Center (WaNPRC). This estimation is non-trivial, as the data consist of ordinal measurements on 16 intervertebral spaces throughout each macaque's spinal cord, with many missing values. We examine the resulting heritability estimates ...

Shape variation is widespread in nature and embodies both a response to and a source for evolution and natural selection. To detect patterns of shape evolution, one must assess the quantitative genetic underpinnings of shape variation as well as the selective environment that the organisms have experienced. Here we used geometric morphometrics to assess variation in plastron shell shape in 1314...

The present experiment was conducted to evaluate the mungbean genotype assess magnitude of genetic variability and understand heritable component variation for seed yield its traits traits. estimates genotypic coefficient variability, heritability advance were high per plant, 100-seed weight, number seeds pod, pods plant nodes on main stem. correlation revealed that had positive significant wit...
