| Utilizando dados de producao de graos advindos de quatro esquemas de cruzamentos na cultivar de milho (Zea mays L.) Centralmex, foram estimadas as variancias geneticas aditiva e dominante, variancia fenotipica, relacao, alem da depressao causada pela endogamia. A analise global realizada conduziu a obtencao dos valores de = 3,494 x 10-4 (kg/planta), = 0,6033 x 10-4 (kg/planta), relacao = 0,180 e depresao causada pela endogamia de 39,5%. Podem ter ocorrido possiveis distorcoes das estimativas devido a selecao para prolificidade, depressao pela endogamia, restricoes de frequencia genica e erro aleatorio associado as estimativas dos componentes de variancia. |

| Knowledge on the genetic system controlling the quantitative traits is important for devising an efficient selection program through the use of a suitable mating design. Forty five Fis were generated by crossing 10 germplasm lines of okra (Abelmoschus esculentus (L.) Moench) namely P1(IC282248), P2(IC27826-A), P3(IC29119-B), P4(IC31398-A), P5(IC45732), P6(IC89819), P7(IC89976), P8(IC90107), P9(IC99716), and P10(IC111443) during summer 2009. Forty five F1s along with their 10 parents were evaluated in a randomized block design with three replicates during late kharif (August-November) 2009 at Vegetable Research Station, Hyderabad, Andhra Pradesh, India, for studying gene action and combining ability of yield and its components. Significant general combining... |

| Although the first inhabitants of western Amazonia domesticated pejibaye (Bactris gasipaes Kunth, Palmae) or peach palm for its fruits, today it is widely planted for its heart-of-palm. Like other domesticates, pejibaye presents a complex hierarchy of landraces developed before the conquest of the Americas. The existence of three landraces (Pará, Solimões, Putumayo) was proposed along the Amazonas and Solimões Rivers, Brazil, based on morphological characteristics. There are some questions remaining about the intermediate landrace being an artifact of the morphometric analysis. AFLPs were used to evaluate the relationships among samples of these putative landraces. DNA was extracted from 99 plants representing 13 populations maintained in the Pejibaye... |
