Genetic control of secondary phloic fibres in jute (Corchorus capsularis L.)

The anatomical characteristics were studied of one X-ray induced macromutant, Undulating stem. This true-breeding mutant produces only primary phloic fibres. The secondary phloic fibres, which are the derivatives of vascular cambium, are found lacking, though there is formation of secondary phloem pyramids from the cambial tissue. Inheritance of fibre (bast) in jute (C. capsularis) is monogenic and recessive.
