Ensaios de variedades de amendoim: resultados de ensaios regionais

[摘要] 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.
