The effect of seedling root length on seed yield in Brassica napus L.Koscielny, Chadwick Bruce 03 January 2012 (has links)
The objective of this research was to determine the relationship between seedling root length and seed yield in spring canola. Field and growth room experiments were conducted using the same eight genotypes. In the field experiment, root length and root area had a strong positive relationship to seed yield with R2 values at the 1-2 leaf stage of 0.90 and 0.93, respectively. Shoot dry weight had a strong positive relationship to seed yield at the cotyledon stage, with an R2 of 0.99. In the growth room, root length was compared to short- and long-term seed yield. The R2 values when root length was compared to short- and long-term seed yield were 0.95 and 0.96, respectively.
