Cultivation

Origin: in Davis, Calif., by E.F. Serr and H.I. Forde, California Agr. Expt. Sta. Introd. in 1968. Franquette × Payne; sibling of Vina. Cross made in 1950; selected in 1957; tested as UC 51-170. Nut: Payne shape; shell seal fair to good, more suitable for in-shell than for cracking; kernel 48% of nut; 70% of those tested had light-colored kernels; matures midseason. Tree: not as productive as Vina in the early bearing stage and does not require a heavy pruning; borne heavy crops in Davis when 8 to 10 years old; 40% of lateral buds producing pistillate flowers; leafs out 14 days after Payne; pollenizer needed; suitable for upper Sacramento Valley and similar situations. Name was selected because the variety seems able to produce with somewhat less cultural care, especially pruning, than more highly fruitful varieties. Fruit:
