The soybean [Glycine max (L.) Merr.] industry is interested in cultivar and climate effects on seed composition. These factors may underlie the known geographic variation in seed protein and oil concentrations. Regression analyses were used to test hypotheses of the effect of temperature and cultivar on oil and protein concentrations of soybean seed using a large data set from the U.S.A. Soybean Uniform Tests. The data set included 20 cultivars representing 10 maturity groups across 60 locations (latitude 29.4 to 47.5°N) for a total of 1863 cultivar by location by year observations. Temperature was determined for each observation as the average daily mean temperature from predicted first pod (first pod at least 5 mm long), using the SOYGRO phenology model, to observed maturity. The mean temperature ranged from 14.6 to 28.7°C among the observations. Linear, quadratic, and linear plateau regression models of oil and protein concentrations vs. temperature were evaluated. The quadratic model gave the best-adjusted R 2 values for oil and protein with temperature, of 0.239 and 0.003, respectively. The analyses showed that the oil concentration increased with increasing temperature and approached a maximum at a mean temperature of 28°C. Unaccounted variation in the protein concentration may be from other factors such as photoperiod, water stress, or high temperatures during seed fill. Protein plus oil had a linear relationship with temperature (adjusted partial R 2 = 0.183). These data document the contribution of climate and cultivar to geographic variability of oil and protein concentrations in the United States.

“…Segundo Burton (1984), correlações negativas entre rendimento de grãos e teor de proteína, apesar de freqüentes, usualmente não são expressivas. Associação positiva entre o conteúdo de proteína e o rendimento de grãos também tem sido observada (Weiss et al, 1952;Kwon & Torrie, 1964;Simpson Junior & Wilcox, 1983). Relação negativa entre rendimento de grãos e teor de proteína foi encontrada, por Wilcox & Guodong (1997), em populações de tipo de crescimento indeterminado, e não foi encontrada em populações de hábito determinado.…”

RESUMO -O objetivo deste trabalho foi verificar se as cultivares de soja lançadas após 1990 para o Estado do Rio Grande do Sul continham, nos grãos, teores de proteína e de óleo diferentes dos contidos nos grãos das cultivares em uso anteriormente a esse ano. Na safra de 1996/97, foi realizado um estudo envolvendo genótipos produzidos em três locais do Rio Grande do Sul. O teor de óleo foi determinado pelo método de Soxlet, e o de proteína, pelo método de Kjeldahl. A maior parte das cultivares lançadas entre 1991 e 1996 apresentou menor teor de proteína e maior teor de óleo do que as mais antigas. A utilização das cultivares União e Industrial como genitores deve ter contribuído para o menor teor de proteína apresentado pelas cultivares. As linhagens experimentais apresentaram teor de proteína tão elevado quanto o das cultivares em cultivo desde antes de 1990, o que pode ter sido causado pela mudança de genitores. As correlações fenotípicas indicaram que existe uma associação negativa significativa somente entre os teores de óleo e de proteína.Termos para indexação: Glycine max, correlação genética, composição química. OIL AND PROTEIN CONTENT IN SOYBEAN GENOTYPES DEVELOPED AFTER 1990ABSTRACT -The objective of this work was to investigate whether oil and protein contents of soybean cultivars released after 1990 for the State of Rio Grande do Sul, Brazil, differ from the contents found in cultivars in use before that year. A study was carried out in 1996/97 involving cultivars recommended at different periods, produced at three sites of that state. Oil content was determined by the Soxlet method, and protein content was determined by the Kjeldahl method. It was found that most cultivars released between 1991 and 1996 showed lower protein content and higher oil content than older cultivars. The use of the União and Industrial cultivars as parents should be one of the main reasons to the lower protein content in these cultivars. The change of parents provided a recuperation in the protein content of new lines up to the level found in the cultivars released before 1990. Phenotypical correlations indicated that there is a significant negative association between oil and protein contents only.
