In this study 130 honeybee colonies in 4 locations (Damavand, Tehran, Qum and Karaj-Savojbolagh) were sampled to determine the phenotypic correlations among 9 morphological and 3 production traits. The morphological traits were length (FL) and width (FB) of fore wing, cubital index (CI), length of hind leg (HL), length of probosics (LP), slender index (SI), length (WL) and width (WT) of wax mir...

The egg quality is one of the most important economic factors for layers that are crucial for hatchability and marketing. Given the low number of egg quality traits records, one of the approaches in estimating phenotypic and genetic parameters is multi trait analysis. The aim of this study was to estimate the phenotypic and genetic parameters of west Azerbaijan native hens egg quality traits by...

adolescents and young adults and their problems is an issue whose importance is obvious to anyone because youth are the founders of our countrys future and requires proper planning to be on leisure. given the importance of leisure,this study to investigate needs assessment and planning how adolescents and young adults spend their leisure time in urban of case study of high school girls and boys...

One of the main problems in vineyards of Iran is sensitivity of grape cultivars to winter cold. Considering the rich genetic diversity of grape cultivars in Iran vineyards and severe cold winter in 2007, this situation was used as a natural treatment in order to identify cold tolerance and assess damages in 21 Iranian grape varieties and 8 European grape varieties in a factorial experiment, bas...

in this study, the number of 1802 longevity records of ewes collected during 1989 to 2010 in breeding station of lori-bakhtiari sheep flocks were used to estimate of genetic, environmental and phenotypic trends for economic lifetime. the breeding values of a ewe’s lifetime were estimated by restricted maximum likelihood procedure under an animal model of univariate analysis. the best linear unb...

Heritability (0.08) was evaluated in a model whereas the comparable group used interaction between herd and control day. The influence of as heritability (0.03). herds years testing (0.04 0.05). Phenotypic correlations milk urea concentration milking traits: daily quantity milk, content fat proteins (P <0.0001). Positive low phenotypic correlation (0.15) found yield, amount (0.10). Between c...

This experiment was conducted to evaluate genetic diversity in 72 peanut accessions (Arachis hypogaea L.), which introduced from seed bank of Australia in training and seed production research center of oilseeds company, Iran. Twelve major morphological traits recorded during 2013 growing season using a randomized complete block design with three replications. The results showed that the differ...

To evaluate heritability, phenotypic and genotypic correlation coefficients, phenotypic and genotypic variances as well as relationships between some of the grain quality traits, an investigation was conducted in a randomized complete block design replicated three times in 2001, using four durum wheat genotypes PI40100, Dipper-6, Oste/Gata, Shova and their F2 and F3 progenies derived from their...

In this study, genetic parameters were obtained for growth and cold tolerance of 99 Fenneropenaeus chinensis juvenile families by means of indoor artificial cooling (starting from 14°C, 2°C/d). A linear mixed model was fitted to estimate variance components using the ASReml software package. Heritabilities estimated for body weight (BW) and body length (BL) of F. chinensis juveniles were 0.078 ...
