Population structures of Brazilian Tall coconut (Cocos nucifera L.) by microsat...
Ribeiro,Francisco E.; Baudouin,Luc; Lebrun,Patricia; Chaves,Lázaro J.; Brondani,Claudio; Zucchi,Maria I.; Vencovsky,RolandCoconut palms of the Tall group were introduced to Brazil from the Cape Verde Islands in 1553. The present study sought to evaluate the genetic diversity among and within Brazilian Tall coconut populations. Samples were collected of 195 trees from 10 populations. Genetic diversity was accessed by investigating 13 simple sequence repeats (SSR) loci. This provided a total of 68 alleles, ranging from 2 to 13 allel...

Autocorrelação espacial das freqüências alélicas em subpopulações de cagaiteira...
TELLES,MARIANA P. DE C.; DINIZ-FILHO,JOSÉ ALEXANDRE F.; COELHO,ALEXANDRE S.G.; CHAVES,LÁZARO J.Dentre as diversas árvores frutíferas nativas dos cerrados, a cagaiteira (Eugenia dysenterica DC.) merece destaque pelo seu amplo potencial econômico. A fim de fornecer algumas informações relativas ao padrão espacial da variabilidade genética desta espécie, foram realizadas análises de autocorrelação espacial das freqüências alélicas em dez subpopulações locais da região sudeste do Estado de Goiás. Foram utili...
Predicting variety composite means without diallel crossing
Chaves,Lázaro J; Miranda Filho,José B. dePrediction of variety composite means was shown to be feasible without diallel crossing the parental varieties. Thus, the predicted mean for a quantitative trait of a composite is given by: Yk = a1 sigmaVj + a2sigmaTj + a3<IMG SRC="Image156.gif" WIDTH=16 HEIGHT=18> - a4<IMG SRC="Image157.gif" WIDTH=14 HEIGHT=17>, with coefficients a1 = (n - 2k)/k²(n - 2); a2 = 2n(k - 1)/k²(n - 2); a3 = n(k - 1)/k(n - 1)(n - 2);...
