Seed dormancy was associated with the presence of an awn, and black hull or red pericarp/testa colorations in two weedy strain-derived [F.sub.2] populations, but the degree of association varied with the cross or genetic background (Gu et al., 2003).
Remember that even with the utmost caution, foxtail awns can blow almost anywhere."
Awns increased yield by 6.2% in 41A (with no significant increase in 42A), increased test weight by 1.7% in both series, and increased kernel weight by 6 (series 41A) and 4% (series 42A).
