Abstract
A slow growing male sterile mutant, 'Ribbon', was first observed in the M2 progenies of 70, 000 R treatment of the dry seeds of Corchorus capsularis L. Genetically, normal leaf trait was found to be dominant over 'Ribbon' trait and male fertility over sterility. The leaf variation is controlled by one factor pair and similar is the case with male sterility. The trend of fluctuation of pollen sterility in F2 population indicates the probability of the presence of two closely linked genes controlling the two traits.
