Gamma radiation induced genetic variability in M2 population of safflower

Mutant characteristics of six M2 gamma irradiated safflower populations were investigated. M2 populations of KUsaf 5058 and 5059 from spine safflower lines gave spineless plants of 44.54 and 47.48 percent, respectively. The mutant characteristics of smooth seed hull were found in six populations. Th...

Summary:Mutant characteristics of six M2 gamma irradiated safflower populations were investigated. M2 populations of KUsaf 5058 and 5059 from spine safflower lines gave spineless plants of 44.54 and 47.48 percent, respectively. The mutant characteristics of smooth seed hull were found in six populations. They were brown striped hull, brown hull and white hull with pappus. The flower color was mutated from orange-red to yellow-orange and yellow. In additional the promising plant type is branching with narrow angle, uniform branch and capitulum height. This plant type would be convenient for harvesting flower and seed. It will be useful for breeding safflower.
