Melhoramento do cafeeiro: IV - Café Mundo Novo

Abstract: Sempre que os responsáveis pela experimentação com o café, no Instituto Agronômico, têm notícias da ocorrência de cafeeiros caracterizados por próxima a Jaú. Ali foi localizada, pelo Eng. Agr. Hélio de Morais, uma plantação de café "Sumatra", semelhante às de Urupês. Tratava-se de uma pequena plantação de 3.000 cafeeiros, formada com 3 a 4 plantas por cova e plantada em 1928 . O cafezal se achava com magnífico aspecto vegetativo, embora fosse pequena a produção nesse ano. Foram selecionados 5 cafeeiros, que re… Show more

“…Variability in heterogeneous cultivars is reported in the studies of Priolli et al (2013) for insensitivity to photoperiod and in Sebastian et al (2010) for grain yield in the USA. The selection efficiency for grain yield in soybean adopting heterogeneous cultivars, such as coffee, dry edible bean, and rice in other crops, has been reported (Carvalho et al 1952, Ramalho et al 1982, Rangel et al 1998, Yokoyama et al 1999, Santos et al 2002. However, it has not yet been reported in Brazil.…”

“…The pure line selection strategy has been used in some breeding programs, such as in coffee (Carvalho et al 1952), beans (Ramalho et al 1982, Yokoyama et al 1999, Santos et al 2002, and rice (Rangel et al 1998). In the soybean crop, the importance of the pure line selection method is also shown in the study of Priolli et al (2013), in which the genetic structure of soybean cultivars in Brazil was systematically evaluated.…”

“…It was the first variety introduced in South America, originating from seeds of an individual C. arabica tree growing at the Amsterdam Botanic Garden. Descriptions of the origin and genetic background of these varieties are presented by Carvalho and collaborators (Carvalho 1958, 1993, Carvalho et al 1952, 1985, 1991a, 1991b. Based on 5 electrophoretic profiles of Typica extracts, the apparent M r of the two main bands were 37.6 + 3.3 and 20.9 + 1.4 kDa.…”
