Soybean Genetics Newsletter


One of the many characteristics that makes soybeans a desirable crop is their ability to fix nitrogen. In order to enhance this ability, it is ne-cessary to look at the variation among various cultivars throughout their life cycle. Genetic studies for Spanish clover (Desmodium sandwicense E. Mey) by Pinchbeck et al. (1980) showed a significant difference among genotypes in their ability to fix nitrogen.
