3. Dwarf 1.
One of the dwarfs obtained from the Bikini test material is an allele of d1. It is somewhat larger and more vigorous than the original d1 but with the same compact growth, unlike the larger and more elongated intermediate allele found by Dr. Brink. It is very satisfactory as a seedling character. It was present in the L289/I205 single cross material used for the Bikini tests.
