          Abstract

          Realizou-se este trabalho com o objetivo de avaliar e selecionar cultivares de alfafa (Medicago sativa L.) mais adaptadas às condições edafoclimáticas da Zona da Mata de Minas Gerais. O ensaio foi conduzido no campo experimental da Embrapa Gado de Leite, em Coronel Pacheco-MG, no delineamento experimental de blocos casualizados com duas repetições. Foram avaliadas 59 cultivares no período de 31/8/1999 a 10/12/2001, realizando-se 16 cortes de avaliação. Avaliaram-se a produção de matéria seca (PMS), altura da planta (AP), vigor (VG), porcentagem de floração (FLO), relação folha/caule (RFC), e incidência de doenças (ID) e pragas (IP). Para PMS, AP, VG, FLO e ID, observaram-se diferenças significativas entre as cultivares. As cultivares P-30, Crioula C-1, Crioula C-3 e Crioula C-2 foram as que apresentaram maiores PMS (13,17; 13,13; 13,00 e 12,48 t/ha/ano, respectivamente). As cultivares apresentaram maior FLO (18,98%) e AP (54,13 cm) nos cortes realizados no período de verão, quando comparado com os de inverno (6,11% e 46,60 cm, respectivamente). Com base nos resultados obtidos, foram selecionadas as cultivares P-30, Crioula C-1, Crioula C-3 e Crioula C-2.

          Translated abstract

          The objective of this experiment was to evaluate and select the alfalfa cultivars (Medicago sativa L.) best adapted to the climate and soil of Zona da Mata, in Minas Gerais, Brazil. The trial was carried out at Embrapa Gado de Leite, in the experiment station located in Coronel Pacheco, MG, using a randomized complete block design with two replications. Fifty-nine cultivars studied between Sept. 9, 1999 and Dec. 10, 2001 were submitted to 16 evaluating cuts. Dry matter production (DMP), plant height (PH), vigor (VG), flowering percent (FLO), leaf/stem ratio (RFC) and disease (D) and pests (P) occurrence were observed. There were significant differences among cultivars regarding to DMP, PH, VG, FLO and D. Cultivars P-30, Crioula C-3 and Crioula C-2 showed the highest DMP (13,17; 13,13; 13,00 e 12,48 t/ha/year, respectively). Taller FLO (18,98%) and PH (54,13 cm) were observed during the cuts done during the Summer compared to those done during the Winter (6,11% and 46,60 cm, respectively). Based on the results of the trial, the cultivars P-30, Crioula C-1, Crioula C-3 and Crioula C-2 were selected.
