O experimento foi instalado no município de Bariri, SP, no ano agrícola 2007/2008. Foram avaliados 29 híbridos de mamona mais os híbridos comerciais Sara e Lyra como testemunha, conduzido em blocos ao acaso com 4 repetições. Foram realizadas as análises de variância individuais e conjuntas para cada característica avaliada. As avaliações realizadas no período de safra com relação a características produtividade de grãos e teor de óleo, verificaram que os híbridos 16 e 21 foram os mais produtivos, com médias de 1452,8 kg.ha-1 e 1347,0 kg.ha-1, respectivamente, e os híbridos 16, 15, 11, 27, 10, 5, 28, 29, 2, 9, 20, 30 e 3 apresentaram rendimentos médios superiores à média geral. A média geral de teor de óleo no período da safra foi de 40% para os 32 híbridos estudados. O híbrido 21 destacou-se tanto em teor de óleo (45,52 %), apresentando maior valor, quanto em produtividade de grãos (1347,0 kg.ha-1) segundo maior valor. Para a época de safrinha, concluiu-se que os híbridos 30, 14, 25, 12, 27, 18, 16, 26, 11, 5, 17, 31, 23 e 32, obtiveram rendimentos superiores a média geral. O híbrido testemunha 30 apresentou a maior produtividade (1272,6 kg.ha-1) e apresentou o terceiro maior valor de teor de óleo (43,65%). A média geral foi de 39,03% para teor de óleo. Verificou-se que o híbrido 21 foi o que apresentou... / The objective of this study was to evaluate the performance of castor bean new hybrids during the main harvest and the second harvest with regard to the following characteristics: grain yield (PG), average height of the plant (AP), seed oil content (TO), stem diameter, (DC), height of insertion of the primary raceme (height of the stem, AC), number of stem nodes (NN), number of raceme (NR), mass weight of 100 grains (M100), number of fruits (NF) and of seeds number (NS). The experiment was done in Bariri, Sao Paulo (SP), during the agricultural year 2007/2008, and it was evaluated 29 castor bean hybrids as well as the commercial castor bean hybrids, Sahara and Lyra, as control; the experiment was carried out randomly in blocks and tested with four replications. It was analyzed individual and joint variances for each feature assessed. The evaluations were performed taking into account the harvest season with respect to grain yield and oil content; it was found that the hybrids 16 and 21 were the most productive ones, with averages of 1452.8 kg ha-1 and of 1347.0 kg ha-1, respectively, and the hybrids 16, 15, 11, 27, 10, 5, 28, 29, 2, 9, 20, 30 and 3 had an average yield above the overall average. The overall average of oil content during the harvest period was 40% for the 32 hybrids studied. The hybrid 21 revealed more prominent among the other hybrids in regard to both oil content (45.52%), with higher value, as to grain yield (1347.0 kg ha-1), the second largest value. During the second harvest, it was found that the hybrids 30, 14, 25, 12, 27, 18, 16, 26, 11, 5, 17, 31, 23 and 32, had yields above the overall average. The control hybrid 30 had the highest yield (1272.6 kg ha-1) and had the third highest amount of oil content (43.65%). The overall average was 39.0% for oil content. It was found...
