Selection of progenies of wild radish germination under high temperatures

Due to the expansion of the wild crop to regions with higher temperatures is important to develop cultivars adapted to high heat. The aim was to select tests for evaluating seed physiological quality of wild radish to estimating genetic characters in order to select cultivars adapted to high temperature conditions. Hundred of half-brothers of wild radish were subjected to germination test and vigor (first count of germination, classification of seedling vigor, accelerated aging test, germination and testing of the first count at high temperature as well as seedling emergence in field. The germination test, first count test, accelerated aging and high germination test (20-35°C) can be used for the selection of wild radish crop populations adapted to germination and field emergence under high temperatures.
