A composite‐cross population, grown to the F7generation under nonirrigated field conditions at Lubbock, Tex., was evaluated for the effect of natural selection on the expression of six simply inherited plant and grain traits in sorghum, Sorghum bicolor(L.) Moench. Results indicated that endosperm type was not affected by natural selection. Genes producing awns, red pericarp color, and presence of a seed testa were at a selective advantage. The linked traits of midrib juiciness and plant color indicated that midrib color was not subject to natural selection, but tan plants were at a selective disadvantage. Data presented indicate which of the traits studied are advantageous in a semi‐arid environment. |
