ABSTRACT.
Datasets of US and Israeli Holsteins were used to evaluate the impact of older generations on ability to predict EBV of young genotyped animals in traditional and single-step genomic BLUP. Inclusion of two (A2) or all (Af) ancestor generations was also evaluated. A total of 34,506 US and 1,305 Israeli bulls were genotyped. Thresholds for data deletion were based on 5 years interval. The number of generations deleted without reduction in accuracy depended on data structure and trait. For US Holsteins, removing 3 and 4 generations of data did not reduce accuracy for final score in Af and A2, respectively. For Israeli Holsteins, the effect of removing older generations depended on the genetic origins of the bulls. Therefore, truncating older data does not decrease the accuracy of young genotyped bulls, while reducing computation requirements and helping to find problems in the population structure. |

Abstract:
The study evaluated the germination performance of bean seeds (BRS Expedito) from different regions of southern Brazil submitted to different germination temperatures (20, 25 and 30º C). Were evaluated to germination (GER), first germination count (PCG), germination speed index (IVG), shoot dry mass (MSPA) and root dry mass (MSR). The seeds from São Mateus (PR) presented the highest average values for the variables GER, PCG and IVG in the three temperatures tested. The temperature increase (20 to 30 ºC) significantly influenced the dry biomass accumulation in the shoots and seedlings roots. The results indicate the existence of a phenotypic plasticity acquired by the cultivar due to local adaptation of the ecotypes.
Resumo:
O estudo avaliou o desempenho germinativo de sementes de feijão (BRS Expedito) de diferentes regiões do sul do Brasil submetidas a diferentes temperaturas de germinação (20, 25 e 30º C). Foram avaliados: germinação (GER), primeira contagem de germinação (PCG), índice de velocidade de germinação (IVG), massa seca da parte aérea (MSPA) e massa seca da raiz (MSR). As sementes de São Mateus (PR) apresentaram os maiores valores médios para as variáveis GER, PCG e IVG nas três temperaturas testadas. O aumento da temperatura (20 a 30 ºC) influenciou significativamente o acúmulo de biomassa seca nas raízes e da parte area das platulas de feijão. Os resultados indicam a existência de uma plasticidade fenotípica adquirida pela cultivar devido à adaptação local dos ecótipos. MenosAbstract:
