Genomic mating in outbred species: predicting cross usefulness with additive and total genetic covariance matrices por Wolfe, M., Chan, A.W., Kulakow, Peter A., Rabbi, I.Y., Jannink, Jean-Luc

“…We developed and tested genomic mate selection criteria suitable for organisms of arbitrary homozygosity level where the full-sibling progeny are of direct interest as future parents and/or cultivars. …”

Plant chemicals and the sexual behavior of male tephritid fruit flies por Segura, Diego Fernando, Belliard, Silvina Ahnahi, Vera, María Teresa, Bachmann, Guillermo Enrique, Ruiz, María Josefina, Jofre-Barud, Flavia, Fernandez, Patricia Carina, Lopez, M. Liza, Shelly, Todd E.

“…We put special focus on polyphagous species whose males congregate in leks, where females exert strong mate selection. We first summarize the main findings related to plant compounds that increase male signaling behavior and attraction of females and consequently increase mating frequency, a phenomenon that has been recorded mainly for species of Anastrepha and Ceratitis. …”

Response to recurrent selection for stover feeding value in pearl millet variety ICMV 221 por Bidinger, F.R., Blümmel, Michael, Hash, C.T.

“…The objectives of the present work were threefold: first, to determine the ranges of grain and stover yields and stover quality traits in full-sib progenies of pearl millet cultivar ICMV 221; second, to assess changes in grain and stover characteristics in trait-specific experimental varieties generated by random-mating selected subsets of these full-sib progenies; and third, to compare laboratory estimates of stover quality traits used for selection among progenies in the full-sib population with direct measurements of stover quality traits obtained through animal feeding trials, using stover samples from replicated field trials of the experimental varieties.…”

Platelet serotonin uptake, N/L ratio and (abnormal) behaviour of pigs with a low or high social breeding value in barren or enriched housing por de Graaf, Sophie

“…A social breeding value (SBV) has been designed that is used to estimate the heritable effect of an animal on the traits of its pen mates. Selecting for high social breeding values for the growth of pen mates might be an indirect way to reduce behavioural problems related to social interactions, but so far the effects of selecting for SBV for growth on behaviour and physiology of pigs are unknown. …”
