Contenido :  Abstract: Weeds are host and multipliers of root-knot nematodes (Meloidogyne spp.). The status quo of the knowledge of the ability of Meloidogyne arenaria to reproduce in weeds is a little unknown. The present study aimed to evaluate the ability of M. arenaria to parasitize and reproduce in different weeds found in Brazil. Thirty-eight weed species were individually inoculated with 5000 eggs and second stage juveniles. Inoculated plants were kept in a greenhouse for 60 days. The design was completely randomized with twelve repetitions. The root system of each plant was evaluated for gall index, number of nematodes per root gram and reproduction factor. M. arenaria showed the ability to parasitize the 38 weed species. It was observed that 76.3% of the evaluated species were susceptible (RF???1.0) to M. arenaria. Oxalis corniculata resulted in the highest nematode RF (34.9). The present study identified for the first time the reproduction potential of M. arenaria on different weeds, showing their polyphagous habit, and indicating species of plants with greater ability to multiply this nematode that need more attention during the integrated management of this root-knot nematodes.

Contenido :  Reproductive traits in breeding herds can be improved through crossbreeding, which results in breed differences, heterosis and breed complementarity. The aim of this study was to estimate group additive genetic and dominance effects for three reproductive traits; probability of artificial insemination (AIP); calving success (CS); and days to calving (DC) for Hereford (H), Angus (A), Nellore (N) and Salers (S) breeds under grazing conditions. Data were obtained from an experiment carried out during 1992?2002 by the Faculty of Agronomy, Universidad de la Republica (UdelaR), Uruguay and Caja Notarial de Seguridad Social. The data set contained reproductive information of 1,164 females from 11 different genetic groups (GG) consisting of crosses between H, N, S and A. AIP, CS and DC were examined in first-calf heifers, while CS and DC were examined in second-calf and 3-to 7-year-old cows. Least square means for each GG and group additive genetic and dominance effects were estimated for each trait. F1 crossbreed females performed better for artificial insemination probability than purebred females. Crossbred A/H heifers had the highest AIPs and CS rates, while crossbred N/H 3-to 7-year-old cows recorded the highest averages for CS and DC. Estimates of group additive genetic effects did not differ amongst A, S, N and H; however, dominance increased the AIP and CS of the heifers.
