Evaluation on Newly Bred Dual-Purpose Peanuts by Irradiation Mutation

To select peanuts for the harvest of both nuts and vines,6 peanut strains newly bred by irradiation mutation were compared according to their agronomic characteristics,above-and under-ground material yields,as well as nutritional value.The results showed that the numbers of branches and pods,and the yields of nuts and vines per plant of TJ were greater than those of the control,Quanhua No.7,at P<0.05 level.The peanut and vine yields of Shang G were 6.16% and 7.32%,respectively,higher than those of the control at P<0.05 level.The peanut and the vine yields of TJ were 5.04% and 6.84%,respectively,more than those of the control at P>0.05.The crude protein contents of Shang G and TJ were significantly higher than that of the control at P<0.01 level.Consequently,these new strains of peanuts,Shang G and TJ,could seemingly be promoted as dual-purpose varieties.
