The results of a study carried out on the variability of stomatal frequency in wheat and other related species at the Indian Agricultural Research Institute indicated that there were significant differences in stomatal frequency among entries, among height groups, and within groups. The stomatal density varied from 36.3 (Macs 11) to 46.7 (HI 4784) per microscopic field, with a mean of 40.8 in Triticum durum; while it ranged from 28.1 (HP 795) to 50.4 (HD 1962) with a mean of 37.12 in T. aestivum. In T. dicoccum, T. carthlicum, barley, and triticale, the mean stomatal frequency was 41.5, 36.4, 46.85, and 38.05, respectively. The mean stomatal density in talls, DI, D2, and D3 groups was 39.3, 35.5, 34.8, and 33.3, respectively in bread wheat. In general, the number of stomata increased with increased plant height. The varieties HP 795, Sonalika, Monti, and Timgalin in T. aestivum; Macs 11, Macs 5, NI 5749, and Macs 9 in T. durum; and P 2923 in triticale had significant fewer stomata per microscopic field
