| Abstract/Contents: | "Seedlings of a group of North American cultivars of smooth bromegrass were examined at the three-leaf stage for pubescence under greenhouse conditions. Southern strains showed 90-98% strongly pubescent seedlings while northern strains had 60-70% strongly pubescent seedlings. Saratoga, although considered southern in type, was less pubescent than all other cultivars except Polar. The degree of pubescence was greater in spring and early fall plantings than in winter plantings, indicating that pubescence depends on good light and temperature conditions. Strains nearly pure for strong pubescence were formed by repeated cycles of mass selection. Few inbred lines showed uniformity for pubescent or smooth seedlings. Pure-breeding smooth stocks were more difficult to produce than highly pubescent strains. Controlled crosses showed partial dominace for pubescence and little difference between reciprocals. Adjacent plantings of pubescent and smooth seedling stocks showed as much as 45% off-type seedlings from seed produced at the interface of plots. Contamination declined to 10% or less at 10 m from the border." |
