Genetic diversity among 115 coffee accessions from the Coffea Germplasm Collection of IAC was assessed using SSR markers. The germplasm represents 73 accessions of Coffea arabica derived from… Expand
Plant biochemistry: A naturally decaffeinated arabica coffee
The adverse side effects of caffeine have increased the market for decaffeinated coffee to about 10% of coffee consumption worldwide (http://www.ncausa.org), despite the loss of key flavour compounds… Expand
Expression and mode of inheritance of resistance in coffee to leaf miner Perileucoptera coffeella
The coffee leaf miner (Perileucoptera coffeella, Guérin-Méneville), is the most serious pest on coffee in Brazil. Coffee varieties with resistance to this pest have been developed in Brazil using… Expand
Caffeine content of Ethiopian Coffea arabica beans
The coffee germplasm bank of the Instituto Agronomico de Campinas has many Coffea arabica accessions from Ethiopia, which is considered the primary center of genetic diversity in coffee plants. An… Expand
Biochemical basis of coffee tree resistance to Meloidogyne incognita
Des cafeiers sensible (Coffea arabica cv. Mundo Novo) et resistants (Coffea canephora cv. Robusta C 2258) ont ete infestes par Meloidogyne incognita. Chez les cafeiers C. arabica infestes, on… Expand
Caffeine content variation in single green Arabica coffee seeds.
Coffea arabica L. is highly homozygotic and caffeine content in most cultivars is reported to be similar (approximately 1%). The caffeine content was analysed using individual seeds of cultivars… Expand
Divergência genética entre progênies de café robusta
Estudou-se a divergencia genetica de 21 progenies de meios-irmaos - 19 do grupo Congoles e duas do grupo Guineano - de introducoes do germoplasma de cafe robusta (Coffea canephora) do IAC. O estudo… Expand
Determination of the number of years in Arabic coffee progenies selection through repeatability
The purpose of this study was to estimate the repeatability coefficient of grain yield in Arabic coffee and to determine the minimal number of annual harvests required for a satisfactory level of… Expand
Caffeine content of diploid coffee species
SOMATIC EMBRYOGENESIS IN GENOTYPES OF Coffea arabica L.
The species Coffea arabica possesses genotypes with special characteristics such as AC1, AC2 and AC3, whose seeds present reduced caffeine content. However, each of these genotypes has just a single… Expand
