چکیده

Abstract The objective of this work was to compare different methods estimate heritability in 30 pigeon pea families from the F3, F4, F5, and F6 generations, for nine variables. experimental design a randomized complete block with three replicates 20 plants per plot. Broad-sense estimated by analysis variance ( A N O V A) [ h 2b-E(MS)], restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) (h2b-REML), parent-offspring regression (h2PO), standard deviation unit (h2UP). h2b-E(MS) h2b-REML estimates were similar seven analyzed For higher genetic control easier selection, values >0.70 two variables four one variable generation. Values h2UP h2PO obtained five variables, respectively. via or correlation showed some outside expected range 0 1. ANOVA [h2b-E(MS)] REML/BLUP [h2b-REML] are best heritability.

Genetic potential of common bean progenies obtained by different breeding methods evaluated in various environments.

Grain yield is strongly influenced by the environment, has polygenic and complex inheritance, and is a key trait in the selection and recommendation of cultivars. Breeding programs should efficiently explore the genetic variability resulting from crosses by selecting the most appropriate method for breeding in segregating populations. The goal of this study was to evaluate and compare the genet...

A strong heritability of psoriatic arthritis over four generations--the Reykjavik Psoriatic Arthritis Study.

OBJECTIVE We have studied the prevalence of PsA in Reykjavik, Iceland, in a population-based cohort, and using the Icelandic genealogy database we have estimated the risk ratio (RR) spanning five generations. METHODS The national identification numbers of all 220 living Icelanders in Reykjavik known to have PsA were linked with the genealogy database. RRs for developing PsA were estimated in ...
