Fertility in Relation to Chromosome Constitution and Behavior in Bromus inermis Leyss1

Synopsis

Synopsis

In 60 clones of smooth bromegrass, 1.2 to 75.4% of the florets were fertile. Among 25 of these clones chromosome number deviated from 54 to 58. Clones with more regular somatic chromosome constitutions were more fertile than aneuploids and clones with fragment chromosomes. Percentage fertile florets was negatively correlated with irregularities at meiosis. Euploids and clones without fragment chromosomes were more regular at meiosis than were aneuploids and clones with fragments.
