Abstract

Portulaca ‘Yubi Primrose’ is a new variety of Portulaca oleracea. This plant has a vigorous, spreading plant growth which produces a pale yellow flower.

Description

Genus and species: Portulaca oleracea.
Variety denomination: ‘Yubi Primrose’.
BACKGROUND OF THE NEW PLANT
‘Yubi Primrose’ originated as a vegetative sport identified in 1999 in a greenhouse in Salinas, Calif., USA. This sport was found in the variety ‘Summer Joy Pink’. The sport possessed pale yellow flowers. Unique flower color was the selection criteria at this stage of breeding.
ORIGIN AND ASEXUAL REPRODUCTION
Plants were propagated from vegetative cuttings using a peat moss-based mix. Cuttings formed roots in 7 to 10 days after sticking without the use of overhead mist. Rooted cuttings were transplanted into and in 15 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 18% nitrogen, 8% phosphorus and 18% potassium was applied every fourth irrigation. The plants were typically watered twice a week. Pots were topdressed with a slow release fertilizer containing 18% nitrogen, 18% phosphorus and 8% potassium. The average air temperature was 24C.
After the initial propagation of the sport, five vegetative lines were made from the original plant in fall of 1999. In spring and summer of 2000 these lines were evaluated for uniformity and ease of propagation. One line was selected in fall 2000 and designated ‘Yubi Primrose’. Uniformity of flower color and ease of propagation were the selection criteria. The following winter it was determined that the variety produced pinkish yellow flowers under low, winter light intensity. The variety has been observed for one more year and, other than the season color change, it has been determined that it is firmly fixed and stable.

COMPARISON WITH OTHER KNOWN VARIETIES
‘Yubi Primrose’ is a distinct variety of Portulaca plant owing to its pale yellow petal color. ‘Yubi Primrose’ is most similar to the variety ‘Summer Joy Yellow’. ‘Yubi Primrose’ possesses slightly smaller flowers than ‘Summer Joy Yellow’ and where ‘Summer Joy Yellow’ has golden yellow flowers, ‘Yubi Primrose’ possesses pale yellow flowers. Under low, winter light conditions (Northern Hemisphere) the petals of ‘Yubi Primrose’ possesses a red-purple blush around the mid-vein region.
