Estimates of genetic parameters in Arabic coffee derived from the Timor hybrid

Genetic parameters of Arabic coffee progenies derived from the cross Villa Sarchi x Timor hybrid wereestimated in order to evaluate their potential for improvement. The experiment was installed in a random block design with tentreatments, eight replicates and eight plants per plot. The parameters cherry yield, plant height, canopy diameter, seed typesand sizes were estimated. Results demonstrated significant differences between treatments for all traits. Greatest yield gainswere achieved when the selection was performed based on plot means and in years of high yields. The variation index b wasthe best indicator of genetic variability. The progenies IAC 3786. IAC 3788, IAC 4094, IAC 4095, IAC 3425, and IAC 3429were outstanding regarding the evaluated agronomic traits, representing progenies of high agronomic potential. All progeniespresented leaf rust resistance
