Comportamento de progênies de cafeeiro cultivar mundo novo

Abstract

The objective of this work is to evaluate the behavior of some progenies from cultivar Mundo Novo, in relation to production. For this purpose an experiment was conduted in Machado-MG, in 1988. The research was coordenated by Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG) in collaboration with Universidade Federal de Lavras, Universidade Federal de Viçosa and Instituto Agronômico de Campinas, being conducted in the EPAMIG (Experimental Farm.). Twenty-four Mundo Novo coffee cultivar progenies yields were evaluated during 14 harvests time. One randomized block design; in split plot arrangement with 24 progenies as plot and two years as subplot was performed with three replicates. Each plot had 9-plant in 3.0 x 1.0 m row spacing and one plant per hole. Yields of processed coffee/ha in 60 kg bags were evaluated. Means were compared by Scott Knott test at 5% at probability (P< 0,05). A wide range among progenies were observed IAC 376-4-26 C807, IAC 388-6-16-2 C 499 EP 108, IAC 464- 1 C 12, IAC 376-4-30, IAC 388-6-14, IAC 379-19-2SSP, IAC 464-2, IAC 502-9-P13 IV, IAC 388-6-13 C 1138, IAC 502-11, IAC 376-4-36 and IAC 501-5-801 presented the highest yield potential, while IAC 379-19P-191 and IAC 474-5 showed the lowest yield. The highest yield progenies during fourteen harvests presented also the best performance in the first harvests.
