Competition and Natural Selection in Soybean Varietal Composites
- C. R. Mumaw and
- C. R. Weber
Composites of pure line varieties grow at the same location showed marked varietal changes during 5 seasons. Varieties having taller height, later maturity, more lodging and greater branching habit increased in proportion suggesting a limitation in the bulk hybrid method of plant breeding. Composites of unlike varieties exceeded the mean yield of their pure lines by more than Composites of similar varieties. Seed number was more important than seed size in the yield advantage of composites. Branching types yielded more than non-branching types in composites.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
