Um dos principais objetivos de qualquer programa de melhoramento genético é desenvolver genótipos mais produtivos, com resistência a fatores bióticos e abióticos e, desta forma, incrementar a produção. Para isto, a rotina dos melhoristas de plantas consiste em criar e ampliar variabilidade, selecionar genótipos desejáveis e testá-los em diferentes ambientes, para um ajuste que permita a expressão máxima do seu potencial. Foram instalados nas safras 2009/10 e 2010/11 experimentos visando indicar variedades de arroz de tipos especiais para cultivo no Brasil e, principalmente, no RS (maior produtor do cereal) com adequado ciclo biológico, tolerância às principais enfermidades da cultura, estatura adequada e com potencial produtivo. |

Abstract: This study aimed to monitor estrous cycle parameters of a human granulocyte colony-stimulating factor (hG-CSF)-transgenic founder female goat and to perform superovulation and embryo recovery (surgical or transcervical method) for further transfer to recipients to quickly obtain offspring. Two experiments were performed using a transgenic (TF) and a non-transgenic (NTF) female. In experiment 1, three estrous cycles were monitored for the following parameters: estrus behavior, progesterone concentration and ovarian activity. In experiment 2, two superovulation/embryo recovery sessions were performed and the recovered embryos were transferred to previously prepared recipients. Data were compared by either t test or Fisher's exact test. The mean interval between natural estrus was 20.7 ± 0.6 and 19.7 ± 0.6 (P > 0.05) days for the TF and NTF, respectively. Progesterone concentrations and ovarian activity were normal and similar between goats. The ovulation rate was similar between TF and NTF (12.0 ± 1.4 vs. 18.0 ± 4.2 CL; P > 0.05). No significant differences in embryo recovery rate (P > 0.05) were observed between the surgical and transcervical methods for TF (69.2 vs. 72.7%) or NTF (100.0 vs. 86.7%). Sixteen embryos from the TF were transferred to recipients, and eight kids were born. Among these kids, the transgene was identified in three (two males and one female), resulting in a transgenesis rate of 37.5%. In summary, the TF is a true founder, since she proved fertility and capacity of transmitting the hG-CSF transgene to progeny, suggesting that the analyzed reproductive traits were not compromised by the presence of the transgene.
