Awned and awnleted populations of spring wheat, Triticum aestivum L. em. Thell., derived by compositing seed from F2 plants and F3 lines classified as homozygous awned and homozygous awnleted, were compared for agronomic and quality performance at two locations. The awned population had heavier kernels and test weight at both locations and a 7% higher yield at one location. The awnleted population headed earlier and had more culms and more spikelets per head. Quality data showed the awnleted population superior in flour yield, loaf volume, farinograph stability, and farinograph valorimeter.
The value of closely related populations for evaluating the effect of simply inherited characters is discussed.
