Ln^G . a naturally occurring allele of the induced mutant Ln.

A mutant of FLORA-DADE, found in a commercial field planting, has heavy pubescence on leaves, stems, and fruit. In crosses to normal FLORA-DADE, Morgan's Wooly (WO^M), and Lanata (Ln) genetic control of the FLORA-DADE mutant was interpreted as a single, incompletely dominant gene allelic to Ln (Table 1). As a result, the symbol Ln^G is being proposed for the pubescent FLORA-DADE mutant. Unlike Ln, which has poor seedling vigor, abnormal seedling growth characteristics, and delayed flowering, ln has good seedling vigor and, except for the heavy pubescence, normal features of FLORA-DADE. Ln^G flowers 2-10 days later than FLORA-DADE and up to 30 days earlier than Ln.
