A total of thirty-nine plants belonging to seven species were analyzed for chemical seed components (soluble solids, lipids, trigonelline, chlorogenic acids and caffeine). The results evidenced that species could be grouped by lipids, chlorogenic acid, trigonelline and caffeine. The existence of great variation among and within species ranging from 24.12 to 30.65% for soluble solids; 8.68 to 17.49% for lipids; 0.32 to 2.15% for trigonelline; 2.91 to 6.38% for chlorogenic acid and 0.80 to 2.50% for caffeine was also observed, indicating the possibility to select plants of interest for the improvement of cultivated coffee species.Item Estimates of genetic parameters in Arabic coffee derived from the Timor hybrid(Crop Breeding and Applied Biotechnology, 2007-06-30) Mistro, Júlio César; Fazuoli, Luiz Carlos; Gallo, Paulo Boller; Oliveira, Antonio Carlos Baião de; Toma-Braghini, Masako; Silvarolla, Maria BernadeteGenetic parameters of Arabic coffee progenies derived from the cross Villa Sarchi x Timor hybrid were estimated in order to evaluate their potential for improvement. The experiment was installed in a random block design with ten treatments, eight replicates and eight plants per plot. The parameters cherry yield, plant height, canopy diameter, seed types and sizes were estimated. Results demonstrated significant differences between treatments for all traits. Greatest yield gains were achieved when the selection was performed based on plot means and in years of high yields. The variation index b was the best indicator of genetic variability. The progenies IAC 3786. IAC 3788, IAC 4094, IAC 4095, IAC 3425, and IAC 3429 were outstanding regarding the evaluated agronomic traits, representing progenies of high agronomic potential. All progenies presented leaf rust resistance.Item IAC Catuaí SH3 - a dwarf Arabica coffee cultivar with leaf rust resistance and drought tolerance(Crop Breeding and Applied Biotechnology, 2019) Fazuoli, Luiz Carlos; Braghini, Masako Toma; Silvarolla, Maria Bernadete; Gonçalves, Wallace; Mistro, Júlio César; Gallo, Paulo Boller; Guerreiro Filho, OliveiroThe cultivar IAC Catuaí SH3 was developed by the pedigree method, from the recombination of the coffee tree H 2077-2-5-46, of the Catuaí Vermelho germplasm, with accession IAC 1110-8, from the exotic cultivar BA10. Cultivar IAC Catuaí SH3 is high-yielding, resistant to coffee leaf rust and tolerant to drought.Item Effective population size and genetic gain expected in a population of Coffea canephora(Crop Breeding and Applied Biotechnology, 2019-01) Mistro, Júlio César; Resende, Marcos Deon Vilela de; Fazuoli, Luiz Carlos; Vencovsky, RolandThis work aimed to study the effective population size and genetic gain in a population of robusta coffee (Coffea canephora Pierre) and verify the possibility of using recurrent selection. The experiment comprised 25 treatments,consisting of 21 C. canephora progenies and four C. arabica (cultivars) grownin Brazil. The experimental design was a 5x5 quadruple balanced lattice, with 24 replications, with one plant per plot. Six harvests were performed in each plant. Statistical analysis was carried out using the mixed model methodology. The analysis showed high additive genetic variability, and the magnitude of the additive components prevailed over that of the dominance components. These facts revealed the plant population liability to undergo recurrent selec- tion, whose expected genetic gains were high. Results suggest that the effective population size and inbreeding degree throughout recurrent selection cycles be monitored. During selective cycles, cloning with weak selection is required due to few progenies.
