Study of Radio-Sensitivity of Strawberry Runners cv. Fortuna under Moroccan Conditions
2019
In recent years, strawberry is being successfully cultivated
in Loukkos perimeter of Morocco and a wide range of varieties are being grown.
The strawberry crop also generates 3 million working days per year. In fact,
all plants are imported and prices are exorbitant. Varietal improvement is
essential if a new impetus is to be given to the morocco strawberry. We have
accordingly started a mutation breeding program by bud irradiation. Strawberry
runners of cv. Fortuna were exposed to
increasing doses of acute gamma rays. The physiological effects induced by
irradiation were evaluated from cutting survival and growth. It has been
determined that the doses of gamma and the varieties used are significant on
the number of surviving plants and plant growth parameters. It was determined
that low doses gamma irradiation respectively affected plant height, leaf
length, leaf width and the number of leaves. These results allowed us, in the
first instance, to fix the optimal dose range for cutting irradiated at 62
Grays.
