In sugarcane (Saccharum spp) breeding, despite the potential use of reciprocal recurrent selection (RRS) to explore both nonadditive and additive effects for economic value traits, to date, no publications have targeted obtaining heterotic groups to support this selection strategy. The aim of this study was to (a) to identify sugarcane gene pools to effectively explore nonadditive and additive genetic effects via reciprocal recurrent selection, (b) estimate genetic parameters, and (c) select parents and cross combinations. Seventy-nine sugarcane families were obtained from crossing 38 parents in a crossing scheme known as disconnected factorial design. The families were evaluated in randomized complete block design with five replicates. The statistical genetic analysis was performed with linear mixed models through restricted maximum likelihood/best linear unbiased predictor. The results revealed that nonadditive effects were predominant in explaining genetic variation for cane yield (t ha-1), pol yield (t ha-1), and fiber yield (t ha-1). For brix, fiber and corrected Pol (PCC) traits, additive effects were predominant. Estimates of specific combining ability and pedigree information allowed the establishment of gene pools for systematic heterosis exploitation through RRS breeding efforts. The prediction of the additive genetic values of parents for selection based on the progeny's behavior obtained via disconnected factorial design is an alternative that should be used in sugarcane breeding programs.

Is the ovarian vascularization correlated with superovulatory response and in vivo embryo production in native brazilian sheep? |

The use of color Doppler ultrasonography in multiple ovulation and embryo transfer (MOET) protocols for sheep allows the real?time monitoring of ovarian blood flow and potentially can be a tool to predict
embryo production in sheep. Therefore, the present study tested the correlation of ovarian vascularization at 36 h after the end of the superovulation treatment and at 12h (Day 15) before the non?surgical embryo recovery (NSER) (Day 16) with estrus response (ER%), duration of estrus (DE), number of corpus luteum (CL), number of anovulatory follicles (AF), number of structures recovered (SR), number of viable embryos (VE; Grade 1-3). |
