Four series of experiments carried out from 1943 to 1951 in five experiment stations of the Instituto Agronômico de Campinas are described, in which 22 castor bean strains were compared with the dwarf variety n.° 38. This series comprises 10 experiments, one in Campinas, one in Tatui, two in Jau, three in Ribeirão Preto, all in the "terra roxa" type of soil, and three experiments in Pindorama, in sandy soil. It was noted that the strains L881, L882 and L883, in Ribeirão Preto, and the strains L 168 and L 881 in Pindorama yielded more than the check variety n.° 38. In all other locations none of the new strains was significantly better than variety n.° 38. The regional behaviour of the strains will be tested in new experiments in the locations where they gave higher yields, before they are released for multiplication.

From 1940 to 1951, 20 experiments were planted with several peanut varieties in order to test them in five different regions in the State of São Paulo. It has been noted that the varieties 76 - Spanish -2B and 40- Roxo produced higher yields (weight of pods in Campinas while varieties 40 Roxo and 54-Roxo yielded larger crops in Ribeirão Preto and Pindorama (table 8). The varieties 40-Roxo and 54-Roxo are both very similar. They have long and narrow pods, the husk is reticulated and the number of seeds per pod varies from 1 to 4, with higher frequencies of 2 and 3. The seed coat is red-purplish. The variety 76-Spanish-2B was received from the the North Caroline Experimental Station, U.S.A., in 1941' In almost all experiments the varieties 40-Roxo, 54-Roxo and 76-Spanish-2B proved to be superior to the check variety 53-Tatu, which largely cultivated in S. Paulo. They will replace variety 53-Tatu in a very near future.

Apesar de pouco difundida em São Paulo a cultura do girassol, resolveu-se executar um programa de ensaios regionais de variedades a fim de se determinar o seu comportamento em algumas regiões do Estado. Assim foram realizados oito ensaios, agrupados em três séries, nas estações experimentais de Ribeirão Prêto, Pindorama e Mococa, durante os anos de 1947 a 1949. A análise dos resultados indicou como mais produtivas as variedades Riscado, La Estanzuela n.° 53, Línea-16, Línea-30 e Sei. Fischer-100, esta última incluída apenas nos ensaios da terceira série.

Three series comprising eight regional trials were undertaken in order to find out the behaviour and production of some recently imported strains of sunflower (Helianthus annuus L.) in three localities of the State of São Paulo during the years 1947-1949. These trials indicated that the following are the most promising strains : Riscado, La Estanzuela n.° 53, Línea-16, Línea-30, Gigante da Rússia n.° 64, and Sel. Fischer-100.
