WALNUT TREE Filed Dec. 29, 1969 INVENTOR Rodney E. Petermcln Mada-Mum A OR N EYS United States Patent 3,142 WALNUT TREE Rodney E. Peterman, 2606 W. Linne Road, Tracy, Calif. 95376 Filed Dec. 29, 1969, Ser. No. 889,008 Int. Cl. A01h 5 03 US. Cl. Plt. -32 1 Claim ABSTRACT OF THE DISCLOSURE A new and distinct variety of English walnut tree, of general adaptability, which is vigorous in growth, of medium size in maturity, of medium form, of medium density with large leaves, the time of leafing' being very early, and a regularand' very productive bearer of large nuts; the nuts-which are very early in forming and relatively early in ripening-are of goodquality and have crisp kernels of excellent flavor.

ORIGIN OF THE VARIETY ASEXUAL REPRODUCTION OF THE VARIETY The present variety of Walnut tree was asexually reproduced by me on my'ranch, located as aforesaid, by budding from the original tree onto California black walnut seedlings. In-maturity, all of such asexual reproductions ran true to the original tree in all respects.

SUMMARY OF THE VARIETY The present variety of walnut tree is distinctively characterized by vigorous growth, medium size and form in maturity, medium density with large leaves, the time of leafing being very early, and regular and very productive (as good or better than Ashley, United States Plant Pat. No. 2,168) bearing of large nuts which are very early in forming and relatively early in ripening, of good quality (comparable to Hartley, unpatented), and with crisp kernels having excellent flavor.

The present variety of walnut tree is further distinctively characterized by a flowering habit which includes an extended period (from very early to late season) of pollen shedding, and hence with a' substantial and desirable overlap of pistillate blooming. Such extended period of pollen shedding spans forty days or more; the pistillate flowers being similar to the Payne but opening eight to ten days earlier, and five to seven days earlier than the staminate flowers.

The present variety of walnut tree is additionally distinctively characterized by its ability to serve as an effective pollinator for other varieties of walnuts, especially the Payne.

The present variety of walnut tree is still further distinctively characterized by the bearing of nuts which ice normally are not subject to kernel; shrivel;- bykernels which average seventy percent light-co10r and,-.thirty,per-

cent amber color; and by kernels which. have minimal veining or speckling, and none black.

I claim:
