Nonlinear principal component analysis (NLPCA) is a descriptive dimension reduction method that examines the relationships between variables and displays results numerically visually in multivariate datasets have linear or nonlinear relationship them. In this study, it was aimed to present basic explanatory information about components emphasize its usability by performing application. data obt...

The benefits of Information and Communication Technologies (ICTs) for agricultural extension purposes and activities are obvious. The main objective of this article is to identify encouraging and discouraging factors in application of ICTs in agricultural extension in Isfahan province of Iran.

Chicken eggs represent an important source of protein to the growing human population and also supply repositories of unique genes that could be used worldwide. The inheritance of shank feathering trait is dominant upon non-feathering shank trait in chicken which is based on two factors: pti-1L and pti-1B that are located on Chromosomes 13, 15, and 24. Using 185 fertile eggs collected from two ...

Genetic variations were studied for 13 accessions of Lolium multiflorum using cytogenetical traits. Karyotype was prepared for 5 metaphases cells of each accession and the traits of total length (TL), long arm (LA), short arm (SA), arm ratio (AR) and centromer index (CI) were determined by micromeasure software. Six accessions were diploid and seven accessions were tetraploid, the basic chromos...

to study combining ability and genetic parameters of seed yield trait in rapeseed, eight lines of rapeseed were evaluated by a design of half diallel cross. seeds of f1 generation and their parents were grown in a 6 × 6 simple lattice design with two replications. according to the analysis of variance, general combining ability (gca), specific combining ability (sca) and mean squares of genotyp...
