Abstract

The sensitivity of the embryo to abscisic acid (ABA) has been reported to play an important role in seed dormancy. Using ditelocentric lines of wheat cv. Chinese Spring (CS, nondormant and ABA insensitive), F2 seeds between monosomic lines of CS and a wheat line Kitakei-1354 (dormant, ABA sensitive) and deletion lines of CS chromosome 4A, germinability of seeds and embryo-half seeds incubated in water and ABA were examined. The results indicated that the long arm of chromosome 4A carded major gene(s) for the embryo sensitivity to ABA and dormancy. Chromosome 2D might be also involved in the sensitivity to ABA.
