Int. Cl. A0111 5/00 US. Cl. Plt.-15 1 Claim ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION The new variety of rose plant herein disclosed originated as a seedling of Lydia (unpatented) Golden Wave (P.P. 2,105) crossed by me in March 1965 in the course of breeding efforts carried on by me at Richmond, Ind., with the object of developing better roses for the commercial greenhouse production of cut flowers. This plant was observed to have better characteristics of growth, strength and flower production than its parents and since its first flowering in October 1966, it has shown an ability to maintain a more constant and intense color in its yellow flowers regardless of temperature and light intensity variations. Asexual propagation of this plant by budding at Hamilton City, Calif, and under my direction has demonstrated that the improved characteristics are fixed and hold true from generation to generation.

DESCRIPTION OF THE DRAWING This new rose plant is illustrated by the accompanying full color drawing which shows the form of the buds, freshly opened and mature blossoms, the characteristics of the wood and young leaves, and the nature of the top and under side of mature leaves, the color of the blossoms being as true as it is reasonably possible to Obtain by conventional photographic procedures.

The new variety of rose plant is an improvement over its seed parent Lydia in that it has a more vigorous growth habit and a more abundant flower production on longer, stronger stems. Also, this new variety is better than its pollen parent Golden Wave in that it propagates better, is mildew resistant, has a prolific growth habit, and its flower has a more constant intense color which does not fade under extreme temperatures or low light intensities. This new variety is to be further distinguished by its shiny dark green and leathery foliage which contrasts well with its yellow blossoms.

I claim: 1

1. A new anddistinct variety of rose plant substantially as herein shown and described, characterized by the distinct intense yellow color of its blooms which does not fade, and by its abundant and continuous flower pro-' ROBERT E. BAGWILL, Primary Examiner
