Abstract
The objective of this work was to evaluate the effect of recurrent radiation on agronomic traits in two barley varieties. The research was carried out at experimental fields pertaining to the Instituto de Investigacion Agropecuaria, Acuicola y Forestal of the Estado de Mexico (ICAMEX). The biological material was irradiated in the Gamma Cell 220 at the Instituto Nacional de Investigaciones Nucleares (ININ). The experimental design was divided plots in the randomized blocks, with four replications. The factor varieties (Cerro Prieto and Puebla) was assigned to the big plots mean while in the factor doses was assignated to the small plots (0, 10, 20, 30, 40 and 50 krad of gamma rays). The variables under study were: germination, number of shoots, plant height, incidence of Puccinia striiformis, days to flowering, days to physiological maturity, spike length and yield. The analysis of variance exhibited no significant differences between varieties for all the studied variables. Regarding to dose, most of the studied variables exhibited significant differences, except for incidence of Puccinia striiformis and days to flowering. The interaction variety x doses showed significance only for the variable days to flowering and days to physiological maturity. The mean separation by Tukey test at 0.05
