مقایسه عملکرد و اجزای عملکرد موتانت های نسل دوم ارقام برنج طارم محلی، حسنی و عنبربو در اراضی شور

In order to study of agronomic characters of the M2 mutant of Tarom maheli, Hasani and Anbarbo rice varieties a field experiment was carried out in paddy field of Ghaemieh village of Bahnamir in 2012. Soil texture was silty loam and salinity rate was between 4-6 ds/m. Treatments are dose of Gama ray in 250, 300 and check of Tarom maheli, Hasani and Anbarbo varieties with M2 mutant of them, in which, it was done by randomly complete block design factorial with three replicates. Panicle number per hill of M2 mutant of Tarom maheli was more related to Hasani and Anbarbo mutants, however, the number of filled grain per panicle of Tarom maheli was lower than M2 mutant of Anbarbo. Panicle length of M2 mutants was higher about 11.5 percent compared to check. The lowest yield was related to M2 mutant of Hasani in dose of 250 equal to 3.8 gr, the highest yield was related to Anbarbo in dose of 300 equal to 9.85 gr.
