Developmental traits affecting low-temperature tolerance
Reciprocal near-isogenic lines were developed for the vernalization determining Vrn-A1 locus producing both spring and winter lines in genetic backgrounds of a non-hardy spring wheat and a very cold-hardy winter wheat. Limin and Fowler (pp. 579-585) report that vernalization requirement and final leaf number influenced timing of the vegetative/reproductive transition, and were major developmental factors affecting low-temperature tolerance.
