ABSTRACT- Barley (Hordeumvulgare L.) is one of the most important cereals in the world which is used as human and cattle feed and for malt production. One of the most important steps in a hybrid and selection breeding program of barley is the selection of suitable parents with high general (GCA) and specific combining ability (SCA) for grain yield. In order to estimate the combining ability and...

Heritability is a central parameter in quantitative genetics, from both an evolutionary and a breeding perspective. For plant traits heritability is traditionally estimated by comparing within- and between-genotype variability. This approach estimates broad-sense heritability and does not account for different genetic relatedness. With the availability of high-density markers there is growing i...

Peach is a temperate fruit species that cultivated under various edaphoclimatic conditions all over the world. In Brazil, in early 1950s, peaches were planted only Sao Paulo state and Southern states, harvest period was restricted to 15 days. Currently, mainly due peach breeding programs, it subtropical areas even high altitude tropical areas, with of 100 Knowledge genetic, phenotypic environme...

Increasingly, researchers are interested in estimating the heritability of traits for nonmodel organisms. However, estimating the heritability of these traits presents both experimental and statistical challenges, which typically arise from logistical difficulties associated with rearing large numbers of families independently in the field, a lack of known pedigree, the need to account for grou...

PURPOSE To estimate the heritabilities of myopia and ocular biometrics among different family types among a Korean population. METHODS We studied 1508 adults in the Healthy Twin Study. Spherical equivalent, axial length, anterior chamber depth, and corneal astigmatism were measured by refraction, corneal topography, and A-scan ultrasonography. To see the degree of resemblance among different ...

It is difficult to give a precise definition of MDS, because some people use the term for a very specific class of techniques while others use it in a much more general sense. Consequently it makes sense to distinguish between MDS in the broad sense and MDS in the narrow sense. MDS in the broad sense inc ludes various forms of cluster analysis and of linear multivariate analysis, MDS in the nar...

The clinical work of psychoanalysts can be thought of in both a narrow and a broad sense. In the narrow sense, it refers to what is commonly thought of as psychoanalytic technique, the methods analysts use to understand their patients and to convey that understanding to them. In the broad sense, it refers to the entirety of their work as clinicians: the content of understanding, as well as such...
