Estimation of variance components and prediction of breeding values in rubber tree breeding using the REML/BLUP procedure Genet. Mol. Biol.
Furlani,Renata Capistrano Moreira; Moraes,Mario Luiz Teixeira de; Resende,Marcos Deon Vilela de; Furlani Junior,Enes; Gonçalves,Paulo de Souza; Valério Filho,Walter Veriano; Paiva,João Rodrigues de.
The present paper deals with estimation of variance components, prediction of breeding values and selection in a population of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell.-Arg.] from Rio Branco, State of Acre, Brazil. The REML/BLUP (restricted maximum likelihood/best linear unbiased prediction) procedure was applied. For this purpose, 37 rubber tree families were obtained and assessed in a randomized complete block design, with three unbalanced replications. The field trial was carried out at the Experimental Station of UNESP, located in Selvíria, State of Mato Grosso do Sul, Brazil. The quantitative traits evaluated were: girth (G), bark thickness (BT), number of latex vessel rings (NR), and plant height (PH). Given the unbalanced...

Genetic improvement of beef cattle through opportunities in genomics R. Bras. Zootec.
Miller,Stephen.
Genomics will improve the efficiency of beef cattle genetic improvement programs through the incorporation of genomic predictions into traditional genetic evaluations. The global dairy cattle breeding industry has been changed considerably in the last year through the implementation of genomic selection. Now proven to work in dairy cattle breeding, the challenge remains for the beef industry to successfully implement this technology. The primary challenge in beef cattle is the required resource population that relates genomic profile to phenotypic performance, which is quite large and its establishment will require collaboration or a significant investment by any one enterprise. Another challenge in beef cattle is the requirement for genomic predictions to...
