Statistical Genetics and Plant Breeding. Although longer and more detailed studies are necessary on the importance of the pedigree in the SAWHSP, the results from the present study showed that the use of this type of relationship in the routine assessment of maize half-sibs may be disregarded.

The SAWHSP methodology was efficient in isolating the additive faalconer variance component from the phenotypic component. Email address subscribed successfully. Please click the link in that email to activate your subscription.

The seeds of the HSP assessed in these experiments were obtained from the harvest of the 10 best plants selected within each of the 20 female rows, in an isolated recombination plot from remnant seeds of the HSP selected by Arriel et al.

The estimate of the components of variance and of the genetic parameters was carried out according to Vencovsky When the relationship among progenies descending from the same half-grandmother was discounted for the HSP selection by the BLP methodology, i.


On the other hand, when dealing with genetic values, this should not happen and the expected gains should be nearer the observed gains.

We never store sensitive information about our customers in cookies. Selection based on the phenotypic value, however, resulted in 15 different ancestors as noted by the pedigree.

A negative correlation of To estimate the introduvcion value without inverting the variance and covariance matrices of the observed data, a time-consuming computer operation, since this matrix is frequently non-diagonal and very large, Henderson proposed an alternative computer method using mixed model equations for obtaining the BLUP. Thus, the gain of selection GS obtained with the BLP is the selection differential SD among the means of the genetic values of the selected progenies in relation to all the assessed ones.

This also occurred in the previous selection cycles Aguiar, ; Pacheco, ; Arriel, It also contributed less to the reduction in the effective size of the population, and consequently reduced future problems with falciner. Expected and realized gains in the CMS maize population after three cycles of half-sib family selection.

However, the indication of a reduction in the effective size of the population caused by an imbalance in the contribution of the selected progenies, as shown by the pedigree structure, draws attention to the problem of an increase in the level of inbreeding.

Table IV also shows that the BLP selected a greater number of progenies stemming from the same ancestor, totaling 11 different maternal half-grandmothers.

P and Ramalho, M. Sometimes, we also use a cookie to keep track of your trolley contents. On the other hand, it can be seen that the BLP was influenced by extreme phenotypic values, because it distributes this influence equally to all the progenies of the same family. Second, it assumes that the gametes of all HSP in the recombination plot have the same frequency, resulting in equal chances of fertilization and in a balanced contribution of each progeny to the next cycle. As in the first three cycles, selection was based on the means over the environments to improve the genetic adaptability of the population, including those with lower densities, by giving priority to prolificacy.
