Recurrent Selection for Seed Weight in Bromegrass, <i>Bromus Inermis</i> Leyss¹

Abstract

Synopsis Among 203 bromegrass clones grown in a topcross nursery, the range in mean seed weight was 0.60 to 1.26 g. per 300 seeds. Ten clones of high and 10 of low seed weight were selected and recombined in separate, isolated polycross blocks. The range in mean seed weight among 986 progeny plants was 0.44 to 1.62 g., and the means of the 2 groups of polycross progenies were significantly different. Almost 50 progeny plants were superior to the best parent clone in seed weight.
