Summary
This report deals with a method of precluding hybrid necrosis lethality in wheat crosses by treatment of F1 hybrid seeds with gamma rays from 60Co source. Two crosses i.e. C306 × Kalyan 227 and C306 × U.S.A. 190 showing severe necrosis were treated with 15 kr and 20 kr doses and plants having mutated chimeras at tiller level and at leaf level were obtained, setting adequate seed for growing F2 generation. The merits of the method have been discussed.
