Conteúdo: | Attention in our soybean (Glycine max (L.) Merr.) improvement has been directed toward developing productive, pest-resistant soybean strains with a higher protein content of the seed than cultivars currently in production. On a dry matter basis cultivars grown in the USA average 40.5% protein and 21,0% oil. Among the approximately 2500 germplasm strains from Asia maintained at Stoneville, Mississippi, about 10% have a protein percentage of 44,5% or higher. These germplasm lines in general are low in productivity, susceptible to one or more pest problems and shatter their seeds as they reach maturity. Our breeding objective in this programme has been to develop productive breeding lines adapted for production in the southern USA resistant to major pest problemsand having a 15% higher level of protein than cultivars now in production. Thus, our desired type would have 46,5% protein and 18.0% oil. Progress in reaching this objective is discussed.
