Description of cross-sectional anatomy of culm and anatomic traits of 25 wheat genotypes (Rht1, Rht2, rht semi dwarf & rht tall)) were studied. Gross anatomy of internodes was described & 35 anatomic traits were measured. Rht1 and Rht2 genotypes are less prone to lodging. Significant influence of dwarfing genes (Rht1 & Rht2) on the expression of various traits including anatomical traits has been confirmed. Rht1 and Rht2 genotypes have stiff culm compared to rht. In general hypodermis consists of sclerenchyma fibrous layer. VB arranged in two circles, inner circle VB is more in basal...
