Studies on crossing in sugar beet. IV. On the number of plants required in a polycross

, : Studies on crossing in sugar beet. IV. On the number of plants required in a polycross. Bulletin of Sugar Beet Research Tensai Kenkyu Hokoku (Suppl. 13): 187-192

Sixteen sugar-beet strains were polycrossed, using 30 maternal plants per strain. Thirty seed lots harvested from one of the 16 strains were evaluated the following year. Highly significant differences in several characters were found among the 30 seed lots.
