The present study investigated the improvement of prediction reliabilities for 3 production traits in Brazilian Holsteins that had no genotype information by adding information from Nordic and French Holstein bulls that had genotypes. The estimated across-country genetic correlations (ranging from 0.604 to 0.726) indicated that an important genotype by environment interaction exists between Brazilian and Nordic (or Nordic and French) populations. Prediction reliabilities for Brazilian genotyped bulls were greatly increased by including data of Nordic and French bulls, and a 2-trait single-step genomic BLUP performed much better than the corresponding pedigree-based BLUP. However, only a minor improvement in prediction reliabilities was observed in nongenotyped Brazilian cows. The results indicate that although there is a large genotype by environment interaction, inclusion of a foreign reference population can improve accuracy of genetic evaluation for the Brazilian Holstein population. However, a Brazilian reference population is necessary to obtain a more accurate genomic evaluation. |

The objective of this research was to determine the effect of dichlorophenoxyacetic acid (2,4-D) callus in peach friable calluses in leaf explants of Bactris gasipaes H.B.K., aiming for further induction of somatic embryos. The explants were inoculated in MS medium supplemented with 30.0 g.L-1 sucrose, 8.0 g.L-1 agar and 2,4-D (0.0, 0.31, 0.62, 1.25, 2.5, 5.0, 10.0, and 20.0 mg.L-1). The cultures were kept in a growth room at 24±2°C under light conditions (50 µmol.m-2.s-1, photoperiod of 16 hours), and also under dark conditions, in factorial arrangement: 2 (light and dark conditions) x 8 (2,4-D concentrations), totaling 16 treatments. On the 14th day of cultivation, occurrences of oxidation and necrosis of the explants were observed and, on the 35th day, the formation of friable calluses, and the percentage of explant area covered by callus cells (EACC) were evaluated. Oxidation was more intense in the cultivations under light conditions, and reduced as the 2,4-D concentrationsincreased. However, the highest concentration, 20.0 mg.L-1, caused necrosis of the explants. The concentration of 10 mg.L-1 was the most efficient for friable callus induction reaching all the explants in the cultures kept in the dark. This concentration also resulted in the highest EACC, with an average of 56.5% of the explant area covered by callus cells. |
