“…Among the Bourbon progenies used in this study, the molecular bands were efficient in separating 'Bourbon Vermelho', 'Bourbon Vermelho Nanicão', 'Bourbon Amarelo' and 'Bourbon Amarelo Nanicão'. The genetic distance between 'Bourbon Vermelho' and 'Bourbon Amarelo' was due to the fact that the latter originated from the spontaneous cross between the wild cultivars 'Bourbon Vermelho' and 'Amarelo de Botucatu' (Carvalho et al 1957). This greater genetic variability could be associated with the fact that progeny 'Bourbon Amarelo' was not submitted to intense crossing cycles and selection in the breeding programs (Maluf et al 2005).…”

“…The genetic origin of Bourbon Amarelo is not well known, but it is probably the result of an expontaneous cross between Arabica cultivars Bourbon Vermelho and Amarelo de Botucatu, similar to Mundo Novo and Acaiá (Carvalho et al, 1957;Fazuoli, 1977). However, Bourbon Amarelo was not exposed to intense cycles of breeding, and therefore could present higher degree of genetic variability than other arabicas selected cultivars.…”

One of the greatest problems in Coffea arabica breeding is identifying precisely any inbred line, based only on botanical and agronomical descriptors, because of the reduced genetic variability of the species, close pedigree origin, which results in small phenotypic variation. Recently, molecular markers have been used for plant germplasm characterization and identification in several commercial species. This work evaluates the reliability of three marker systems: RAPD, AFLP and SSR, to characterize the genetic variability of commercially-used Coffea inbred lines developed by the Instituto Agronômico (IAC), and their potential for cultivar identification. All methods identified polymorphisms among the cultivars. The genetic diversity recognized by the methods is very similar, although is very narrow. RAPD and SSR marker systems grouped more efficiently the evaluated cultivars according to parental origin. None of the methods allowed inbred line identification. Therefore for varietal protection, it would be necessary using a combination of botanical, agronomical and molecular markers descriptors for precise cultivar identification.

Basicamente, a limitada variação fenotípica observada em cultivares é o resultado de uma estreita variabilidade genética em C. arabica associada com uma origem genealógica próxima. Recentemente, os uso de marcadores moleculares tem contribuído para a caracterização e identificação de várias espécies de interesse comercial. O objetivo deste trabalho foi comparar a confiabilidade de três tipos de marcadores moleculares, RAPD, AFLP e SSR, para a caracterização da variabilidade genética e uma possível identificação de linhagens comerciais de Coffea desenvolvidas pelo IAC. Os métodos avaliados permitiram identificar polimorfismos entre cultivares. A variabilidade genética detectada por eles é muito semelhante, ainda que reduzida. Marcadores do tipo RAPD e SSR foram mais eficientes em análises de parentesco, e o agrupamento das linhagens correspondeu à sua origem genealógica. No entanto, nenhum dos métodos testados permitiu a identificação individual de linhagens. Neste caso, a utilização conjunta de descritores botânicos, agronômicos e marcadores moleculares é recomendada para a identificação precisa de linhagens, visando processos de proteção legal de cultivares de Coffea.

“…Incluíram-se no experimento, denominado Ensaio de Progênies 16 (EP16), 92 progênies S 1 de 'Mundo Novo', 12 seleções S 2 dessa cultivar, provenientes de cafeeiros selecionados em 1943 (CARVALHO et al, 1952), seis das melhores seleções da cultivar Bourbon Amarelo (CARVALHO et al, 1957) e sete da cultivar Bourbon Vermelho, no total de 117 progênies. Bragantia, Campinas, v.64, n.4, p.533-546, 2005 As 92 plantas matrizes S 1 de Mundo Novo haviam sido selecionadas em 1952 em cafezais, com idades diferentes, em vários locais, sendo 35 na Fazenda Ferrari, 6 no Sítio Aparecida, 30 no Sítio Bacuri AB, 10 no Sítio Bacuri AG, 2 no Sítio Bacuri JS e 9 na Fazenda Cachoeira.…”

EVALUATION OF THE CULTIVARS MUNDO NOVO, BOURBON AMARELO AND BOURBON VERMELHO OF COFFEA ARABICA L., IN CAMPINAS, STATE OF SÃO PAULO, BRAZILCoffea arabica L. cv. Mundo Novo is the most outstanding coffee cultivars studied at the Instituto Agronômico, Campinas, State of São Paulo. Besides its rusticity, this cultivar has showed high yield capacity in all Brazilian coffee growing areas. In order to further diversify the Mundo Novo genetic background, new selection of mother trees was undertaken, in 1952, in six sites where former selections were made in Urupês, SP. Four groups of coffee progenies were planted to be compared at the Central Experimental Station, in Campinas, SP: 92 new selections (S 1 ), 12 progenies of selected Mundo Novo (S 2 ), 6 selected progenies of Bourbon Amarelo and 7 progenies of Bourbon Vermelho cultivars of C. arabica. The 117 progenies were planted in a randomized block design, with one-plant plots and 21 replications. Yield data were collected from individual plants during 33 consecutive annual harvests, from 1955 to 1987. Prior to the 1985 harvest, observations were made on the shape of plants, vegetative vigor (IAV index, 1 to 10 points varying from the worst to the best, respectively), fruit ripening (1 point for early, 3 for medium and 5 for late ripening, respectively), seed characteristics, such as flat beans, peaberry and elephant beans, and seed size. Significative differences were found in the yield inside and between progenies groups -Mundo Novo S 1 , Mundo Novo S 2 , Bourbon Amarelo and Bourbon Vermelho. The average yield of Mundo Novo S 1 was 6% superior to the of Mundo Novo S 2 , and both groups of Mundo Novo S1 and S2 were more productive than Bourbon Amarelo (39 and 30%) and the progenies of Bourbon Vermelho (112 and 99%), respectively. Among the 30 highest Mundo Novo yield progenies, 4 belong to S 2 and 26 to S 1 , Mundo Novo progenies, indicating the efficiency of the selection of S 1 progenies. The highest yield Mundo Novo progenies have medium maturation. However individual plants in the progenies were classified as early, medium or late maturing plants. The Mundo Novo progeny CP447 gave larger number of plants with early fruit ripening and CP502 gave the highest number of late plants. All the best Mundo Novo progenies presented normal flat, peaberry and elephant beans seed percentages and seed size. The progeny CP474 gave several plants with larger seeds. The highest yield S 2 Mundo Novo progenies such as P388-17, MP376-4 and the S 1 CP502, CP515, CP474, CP447, CP501, CP543, CP475, CP464 and CP441 have already been multiplied in seed plots and are being extensively planted in all coffee regions of Brazil.
