Barley breeding program in Brazil has focused on characteristics associated with malting for beer purposes as the main economic application for this crop. The breeding process focused on selection for grain yield, disease resistance and malting quality. The objective of this work was to quantify the genetic gain in barley grain yield from 1968 and 2008 in Brazil and to identify the physiological characteristics associated with the increase of grain yield. Field experiments with five 2-row barley cultivars were tested from 2011 to 2013 in the absence of biotic and abiotic stresses and with mechanical restriction to lodging. The ANOVA showed no genetic gain until 1980 with average grain yield of 4.632 kg/ha. After 1980, there was a productivity increase of 59.9 kg/ha/year. No correlation was observed between total maturity biomass and the year of release of the cultivars, while harvest index and plant height, were significantly improved. The main component associated with grain yield was the number of grains/m2 , due to the higher number of spikes/m2 associated to a greater contribution of the tillers in the modern cultivars. |

Hormonal protocols aiming at dilation of the sheep cervix were developed to allow access to the uterus. Despite the proven efficacy of these protocols, little is known about these drugs used on embryonic quality. Thus, this study evaluated the influence of the hormonal protocol of cervical dilation (based on estradiol benzoate, d?cloprostenol and oxytocin) on the expression profile of genes related to incidence of apoptosis (Bax and Bcl-2), stress (Hsp90 and PRDX1) and pluripotency maintenance (Oct-4 and NANOG). For this, two experiments were conducted. In conclusion, the cervical relaxation protocol based on the administration of estradiol benzoate, d-cloprostenol and oxytocin may temporarily alter the expression of NANOG and OCT4 genes in surgically recovered sheep embryos. |
