Parents, and first- and second-generation
plants, of a vetch species cross. One parent
(1), Vicia sativao produces good seed
and fcrage yields but little hard seed. The
male parent 12), V. angustifolic, is small
but produces hard seed. Hybrids (3) were
vigorous and averaged 39%o hard seed,
Much variation was found among the second-generation
plants (4 and 5), but some
were vigorous and produced a high percentage
of hard seed.
