O coqueiro é uma das culturas de maior importância socioeconômica, na geração de empregos e na sustentabilidade dos agroecossistemas. Porém, a falta de material genético melhorado tem limitado a expansão dessa cultura. Este trabalho visa avaliar o comportamento de cultivares de coqueiro em condições de tabuleiros costeiros de Sergipe. O delineamento experimental utilizado foi de blocos ao acaso com 13 tratamentos e quatro repetições. Cultivares avaliadas: (AVeBrJ x GBrPF); (AVeBrJ x GBrMe); (AVeBrJ x GBrSJM); (AVeBrJ x GOA); (AVeBrJ x GPY); (AVeBrJ x GTG); (AVeBrJ x GRT); (AVeBrJ x GRL); (AVeBrJ x GVT); (AVeBrU x GOA); (AVeBrJ x GBrJ); (GBrPF) e (AVeBrJ). Dos oito caracteres avaliados, todos apresentaram diferenças significativas entre cultivares (P<0,01). O híbrido AVeBrJ x GBrJ se mostrou como uma das cultivares mais promissoras, pois teve bom desempenho para todas as características avaliadas. |

Abstract: This study aimed to assess the luteal dynamics of pregnant and non-pregnant Saanen goats throughout an estrous cycle by B-mode and color Doppler ultrasonography (US) associated with a P4 hormonal assay. Furthermore, a cutoff point was chosen to determine the corpus luteum (CL) functionality by luteal biometry (LB) measurement and luteal blood flow (LBF) assessment. Ultrasound assessment was carried out daily throughout an entire estrous cycle (21 days) in 23 Saanen goats pre-synchronized and inseminated in the breeding season. The plasmatic P4 concentration was determined daily by radioimmunoassay. LB parameters (diameter, area, and volume) were measured using the maximum area of a cross-section of the CL. LBF assessment was performed subjectively by percentage of area of colored pixels and objectively by calculating the number of the colored pixels. Eventually, 45.0% (9/20) and 55.0% (11/20) of goats became pregnant and or remained non-pregnant, respectively. The LB and LBF demonstrated value stabilization on the 9th day of the estrous cycle and maximum values on the 12th and 13th days of the estrous cycle, respectively. LB presented a progressive decrease in the luteal regression phase, whereas the LBF decreased abruptly in association with P4. The LBF values were more reliable in predicting the luteal functionality when compared to the LB data. The number of colored pixels accurately predicted values of P4 >1.0 ng/mL, reaching only 17% of the maximum values, and 1200 colored pixels as a minimum cutoff point when compared to the use of 53% of the maximum values and a minimum luteal diameter of 9.0 mm as cutoff point for P4 >1.0 ng/mL. The LBF assessment was more informative about the CL functionality throughout the complete luteal phase when compared to the LB. The use of the number of colored pixels is indicated for research regarding luteal functionality due to their greater correlation with P4 values. In addition, the luteal subjective evaluation can be used under field conditions due to greater convenience and similar pattern of correlation with P4.
