Walnut Varities in The

World By

Allah Dad Khan

Chandler 

•Harvests mid-season; large smooth oval nut, with good shell seal, and high quality kernel. Kernel color excellent, light grade consistently 90% or better. Has potentially high fruitfulness with 80-90% of lateral buds fruitful. Medium size tree is a moderately vigorous and semi-upright, highly productive tree. Pollinizers are Cisco and Scharsch Franquette.

Howard Harvests mid season. 80%-90% lateral bud fruitfulness. Leafing date is 15 days

after Payne. Nut–large with good seal. Kernel 90% light. Tree–small to medium, semi upright. Nut susceptible to blight due to late leafing.

Pollinizers are Scharsch Franquette or Cisco.

Tulare (USPP #8268)

•Harvests mid-late. Recently introduced by University of Calif., leafing is approximately 12 days after Payne. Blooms late. Displays high production potential. Nut is large and well sealed. Kernel crackout is approximately 53% with kernel color at 85% light. Tree upright with moderate vigor. Potential hedgerow variety.

Forde (USPPA#10/913,249) New UC Release

• High early yields and a harvest date that averages 5-10 days before Chandler. Leafing date is 5 days before Chandler. Nuts are oval to round, medium textured with good seal. Kernel color light. Pollenizers are Payne, Vina, Serr and Sexton.

Gillet (USPPA#10/912,781) New UC Release

•Has high yields on young trees and a harvest date 10-20 days before Chandler. Leafs a week before Chandler. Pollenizers are Payne, Vina, Serr and Sexton.

Sexton (USPPA#10/912,852) New UC Release

•Characterized by very high yields on young trees and a harvest date at least one week before Chandler. Sexton leafs out a week before Chandler. Potential pollenizers are Howard, Tulare and Chandler. Nuts are relatively smooth and round with a good seal and strength. Kernals are light colored.

Cisco •

Cisco is late leafing, laterally fruitful, and a potential pollinizer for Chandler and Howard. It leafs out 30 days after Payne, and is ready to harvest 3 weeks after Payne. In growth habit, Cisco is semi-upright and relatively small similar to Chico and Pedro. The nut shell is medium to light in color with medium texture, similar to Franquette. The nut and kernel are slightly larger than Franquette, but there can be problems with kernel quality. Kernel color is variable. Its main attribute is as a pollinizer for the Chandler and Howard varieties.

Hartley

•Harvest mid to late. Consistent producer with high quality nuts. Leafing date is 16 days after Payne. Less susceptible to coddling moth and blight. Nut is large. Shell well sealed. Tree is medium to large, moderately spreading. Scharsch Franquette works well as a pollinizer.

Scharsch Franquette 

•Late harvest. Nut size is small and well-sealed, very good quality light kernel. Trees are large. Vigor is moderate to high and tree shape is upright. Good pollinizer for Hartley and Chandler

Serr•

Yields can be disappointing due to pistillate flower abscission. Other varieties may also drop flowers, but Serr is most severely affected. Serr has 30 to 50 percent lateral buds that are fruitful. Leafing date is approximately 1 day ahead of Payne. Suitable pollinizers include Chico, Tehama, and other varieties that shed pollen in mid bloom. Harvest timing is early to midseason. Serr nut size is large (7.6 grams per kernel). The nut is a Payne type with a fair-to-good shell seals. Color is very good. Kernel percentage is high at 59 percent. Serr tree size is large. Shape is moderately spreading and vigor is good to excessive. Serr is susceptible to codling moth and blight.

Vina•

Cross of Franquette x Payne. Vina's fruitfulness is high to very high with 80 to 90 percent of the lateral buds fruitful. Vina leafs 7 days after Payne. Pollinizers would include those varieties which shed pollen in midseason such as Chico, Tehama, and some newer varieties like Howard and Chandler. Vina harvests in early to midseason. Nut size is medium (5.7 grams per kernel), slightly larger than Payne. Nut shape is pointed, somewhat similar to Hartley, but less flattened on the base. Seal is good. Vina's kernel color is good at 60 percent light with 48 percent kernel. Tree size is medium and shape is similar to that of Payne. Vigor is good. A good pruning program is necessary to maintain nut size and tree vigor. Vina seems to exhibit less blight compared with such varieties as Ashley and Payne. Blight can be a problem.

Ivanhoe •

(PP21718) A new and distinct variety that produces large, light-colored kernels and high yields. It is precocious and 100% laterally fruitful. Ivanhoe leafs out with Payne and Serr but the female bloom is about a week earlier than the male bloom. Ivanhoe harvests 4 weeks before Chandler, similar to Payne or Serr. The tree is moderately vigorous and is not resistant to blight, so consider planting in the driest of walnut growing regions.

Solano (USPP #13/694,337) •

Solano is a new variety released in 2012 by the University of California. It leafs out 10 days before Chandler and 7 days after Payne. Solano appears to harvest 2 weeks before Chandler. It is precocious and is 100% laterally fruitful. In trials Solano has shown low susceptibility to blight when compared to other early varieties. The tree appears to produce high yields and consistently light kernels. Kernels are 8.0 grams and edible yield of kernels is 55%. Nuts are uniform and oval with suitable strength and seal for in-shell use. However, kernels are easily removed as halves from the nut for processing. Solano's growth habit is of average vigor and size similar to Chandler. Suitable pollenizers are Chandler, Tulare, or Howard.
