✦ Synopsis

Previous studies have reported a correlation between genome size and relative maturity among plant species. The objective of this study was to determine whether such a relationship exists in soybean. Twenty cultivars, representing maturity groups ranging from 000 to IX, were analyzed using flow cytometric procedures. A 15% difference in genome size was observed ranging from 'BSR 201' at 2.88 pg to 'Maple Presto' at 2.51 pg. A highly significant correlation (r = 0.55) was observed between maturity and the genome size of the 20 cultivars.

Genome and body sizes were measured in 38 species of turbellarian flatworms and 16 species of copepod crustaceans. Significant positive relationships existed between genome size and body size in both groups. The slopes of these regressions indicated that increases in cell volume are reinforced by in
