Abstract: In the present investigation eight genotypes of C. olitorious L. (OMU-09, OMU-42, OMU-43 OEX-16, OIM-45, JRO-204, JRO- 524, JRO-8432), and one genotype of C. capsularis L. (Fanduk) were included to evaluate their morphological and anatomical characteristics. Mean performance of six different morphological and nine different anatomical characters at 30, 60, 90 and 120 DAS of the crop revealed plant height, basal diameter and inter-node length increased sharply between 30 and 60 days age and slowly between the latter two growth stages; mid-diameter and top diameter reduced between 30 and 60 days and increased between the latter two growth stages; number of nodes increased steadily all along. Fibre anatomical characters revealed that total bark diameter and difference between fibre wedge tip and outer bark layer increase sharply between 30 and 60 days; average length and width of fibre cell wedge, number of fibre cell block at base and at middle increased linearly all along up to 120 days age of the crop. Number of fibre cell in each block increased sharply between 30 and 60 days and slowly between the latter two stages. All the plant morphological and fibre anatomical characters exhibited high variation at different growth stages. The anatomical characters may be considered as an easy and effective method for screening genotypes without destructive sampling within a short period....
