Genotype-Environment Interaction in Laying Tests of Poultry

Genotype-environment interaction in transmission disequilibrium tests.

Transmission disequilibrium tests (TDTs) provide an approach to the detection of associations between alleles at marker loci and risk of complex disorders. The logistic regression approach to TDTs proposed by Sham and Curtis (1995) is generalized to provide separate tests of the main effects of marker loci on genetic risk and genotype-environment interaction (G x E) arising because multiple all...

Stability Analysis of Genotype × Environment Interaction Effect on Sugar Yield in Sugar Beet Hybrids

   Testing plant varieties under different regions is necessary to assess their stability. In this study, 17 sugar beet genotypes were evaluated in a randomized complete block design with six replications in five regions including Karaj, Hamedan, Miandoab, Mashhad, and Shiraz. After checking the homogeneity of mean squares in five experiments by Bartlett’s test, analysis of the combined was per...

Genotype - - Environment Interaction

T HE experiment involved 48 pairs of male Holstein fraternal twin calves. Two methods of raising calves were contrasted: (A) High fat (20%) and protein (20%) vealer ration fed from 3 days of age to a market weight of 128 kilograms. (B) The same vealer was fed up to a live weight of 56.7 kg, followed by pelleted grain mixture fed ad libitum and hay offered to a maximum of 0.9 kg per day. Twin pa...
