Narrative
The parent plant (R6P1) produces a profuse amount of ligules, whereby petals, in addition to being produced by ray flowers on the periphery of the blossom, are also present on a substantial portion of disk flowers in the interior of blossom. This results in a far greater number of petals per blossom than is commonly found in compass plant, with mature achene production from both ray and disk flowers. All blossoms on R6P1 expressed the profuse ligule trait; both staminate and pistilate disk flowers were present. Anthers from staminate disk flowers of R6P1 were less well developed than those of other compass plant genotypes. First bloom date and plant height of R6P1 average approx. late June at Ardmore, OK and 17 cm, respectively. Inheritence of the profuse ligule trait is unknown. Progeny of R6P1 have not been evaluated for this trait. Chromosome number is 2n=2X=14; one hundred achene weight averages 2.54 g.

Pedigree
Description:
Consists of half-sib seed harvested from a single genotype (R6P1) expressing the profuse ligule trait. This genotype originated from seed collected from asite (OKWS-1) in southern Oklahoma. R6P1 wsas grown in the same nursery as those plants used to produce NF-1 compass plant; seed was harvested from R6P1 in 2000 and 2001 and bulked to comprise NF-1 Profuse Ligule. Attempts were not made to prevent pollination between R6P1 and other plants in the nursery.
