Genetics of seedling vigour and tillering time was investigated in a cross between two upland cultivate, D 6-2-2 (green) and HY-256 Purple (purple) during 1987-1989 at the Agricultural Research Station, Mugad by subjecting the data on parents, F, and F₂ to the analyses of frequency and chi-square distrubution. Both the characters behaved as incomplete dominant and were primarily under the influence of three (2737 for good vx moderate vigour) and four (9:247 for early/inter-mediate vs late tillering) interacting genes, coupled with the action of polygenes or modifers resulting in continuous distribution of segregants in F₂
