We studied the relation of the C gene to the length of the awn, the coleoptile, the first leaf, and the culm and its internodes, using near‐isogenic lines of Triticum aestivum L. The club and lax lines represented two contrasting backgrounds: ‘Suwon 92’ (a lax cultivar)/8*‘Omar’ (a club cultivar), and ‘Albit’ (a club cultivar)/7*‘Burt’ (a lax cultivar). The C gene reduced culm length in both the club and lax background. The C gene inhibited length of all internodes, with the most reduction occurring in the peduncle and progressively smaller reductions in lower internodes. Awn length was reduced, but not proportionally to culm length. First leaf length was reduced 6 to 10% in the presence of the C gene. No difference occurred in coleoptile length between the two spike types in the Omar background, whereas coleoptiles of the club lines were longer than those of the lax lines in the ‘Burt’ background.
