Effect of gamma rays on Quality characters of three variety of bean

Abstract

This study was conducted at Al-Dahaara, Al-Sumawa, Iraqdu ring 2015-2016 growing season to study the growth and yield responses of tree fababeans cultivars namely Local (C1) ,French(C2) and Aspanish (C3) to seven doses of gamma rays (0 ,1, 2, 4, 6, 8, 10, 12 Kr) using Co60 on. Randomized Completely Block Design (R.C.B.D) were used with three replicates. Local Varity was significantly superior over others in N contained in leaves reached (7.05%) respectively. Additionally, Local Varity was significantly superior in N and protein percent contained in seeds (4.24% and 26.3, respectively). French Varity gave the highest K and protein percent in seeds (0. 90% and 26.3%, respectively). The gamma radiation (6Kr) significantly increased the average of N, K contained in leaves and with an increment ratio (8.06%, 1.24%%, respectively). 10Kr significantly increased the average of P, K and protein percent in seeds with an increment ratio (0.35%, 0.82%, and 28.6%, respectively).The combination of (C1+6Kr) treatment significantly increased N and protein percent in seeds (4.91%, 30.7, respectively). The dual treatment of (C2+4Kr) treatment significantly increased K reached (1.35%).
