Abstract

The effect of mutagenic treatments on the character association was studied in the M3 generation of two varieties of groundnur. Negative association between height of main stem and pod yield in TMV 9 and between number of branches and number of pods in Ah 7911 was observed in the combination treatment against the positive association in the respective parent populations. The positive association between number of flowers on one hand and number of pods and pod yield on the other which existed in the control population of, TMV 9 was not observed in 80 mM of EMS treatment. The possibility of selection for yield with Improved plant architecture from mutagen treated populations was indicated by the altered character association.
