90-027-21 (Tulare x Sinensis #5) (selected 1998): We are interested in this selection for its apparent resistance to boron. Yield is very good and this could be used as an early in-shell producer. It is a protandrous, upright, vigorous tree that leafs out and harvests close to Payne. The shells are strong, well sealed, and shaped like Vina. Nuts yield only 48% kernel and kernels average 7.0 g. Kernel color has been mostly light but not excellent. Blight has been severe on unsprayed trees in wet years but little blight has been observed in sprayed blocks even though it leafs early. Nuts tend to have a white interior lining on the shell, sometimes don’t fill well at the blossom end, and have packing tissue with a rather woody center. Tree is upright and branchy with a dense canopy and is likely easy to train. Kernel weight and percent are concerns but this selection continues to produce excellent yields. Possible discard. 2003 (Trials: Deseret, Stuke, Conant, Deardorff, Scheuring)

90-027-23 (Tulare x Sinensis #5) (selected 1998): This short-season sibling of the previous selection leafs out close to Chandler but harvests about two weeks earlier. It exhibits good shell strength and kernel color. Kernels average 7.6 g and nuts average 52% kernel. Nuts are Vina shaped and have a striped appearance. This is a vigorous, thrifty tree that consistently harvests about a week after Payne with good yield. (Trials: Deseret, Stuke, Conant, Deardorff, Carriere)

91-077-6 (Howard x 85-008) (selected 2000): This protandrous tree harvests close to Payne time but leafs about a week later than Payne. Yield has frequently been huge on this precocious selection. The large 8.9 g kernels have shown consistently excellent color with easy removal of halves. The large, round, smooth-shelled nuts average 56% kernel but shell strength and seal may prove insufficient and it often shows problems with incomplete shells although this was not seen this year. Not for in-shell use and shows boron sensitivity, but could be an early cracking selection if shell strength is adequate. (Trials: Conant, Sierra Gold, Scheuring, Bonturi, Deardorff)

91-077-40 (Howard x 85-008) (selected 2001): This is a rather small tree characterized by precocity, excellent yield, protogynous bearing habit, and large kernels averaging 8.2 g. Color continues to show a pattern of excellence at Davis but not at other locations. Nuts are well sealed with 51% kernel and strong shells. Harvest averages a week before Chandler and yields have been consistently huge. The large yields can stall growth. This selection may be of interest under power lines or in hedgerows.

*91-090-41 (87-009 x Chandler) (selected 1999): This early to mid-season harvesting selection is notable for its light color relative to other selections in locations with generally poor color. It has an attractive shell appearance and growth appears to be upright. The nuts have thin shells and average 59% kernel. Seals and strength are not adequate for in-shell use. Yields have consistently been very strong, and color of the 8.0 g kernels has been mostly light to extra-light with easy recovery of halves. Harvest is about two weeks before Chandler and blight has been low. Grower comments and Diamond data suggest consideration for release but shells and seals are rather in many cases and remain a concern. (Trials: Deseret, Stuke, Conant, Sierra Gold, Deardorff,)

92-070-12 (Soleze x Chandler) (selected 1999): Attributes of this selection include excellent kernel color, easy removal of halves, excellent shell appearance, 7.3 g kernels, and 54% kernel yield. This harvests a little earlier than Chandler and blight incidence has been low. Shells are very smooth textured and light colored but seals and shell strength are rather weak. Great nut appearance and very high value scores from Diamond crackout in multiple years and locations. Nut size is larger and more consistent than Chandler with less variability, a greater percent kernel, and fewer small nuts. Possible discard 2003. (Trials: Deseret, Stuke, Conant, Deardorff, Crane Jr.)

93-026-6 (Chandler x Sinensis #5) (selected 2001): Good yield with harvest averaging about a week after Payne or two weeks before Chandler. This protogynous selection has large Hartley-shaped nuts with solid shells and seals that yield 50 % kernel. The large 8.7 g kernels have had mostly light to extra light color. Stem end holes should be watched but have been mostly acceptable. Although rather Hartley-shaped and large, the shells can be irregular and are probably not be consistent enough in appearance for in-shell use. Veins and tip shrivel are consistent defects. (Trials: Driver, Deseret, Stuke, Crain, Conant, Noreen, Sierra Gold, Scheuring)

93-028-20 (Chandler x PI 159568) (selected 2001): Tulare timing with large, oval, very attractive nuts. This selection leafs a few days before Chandler but harvests about two weeks earlier and has had little blight. The smooth, attractive, solid shells have good seals and 55% kernel. The very plump, Sunland-shaped kernels average 8.7 g and color is excellent. Yield has been very good the last two years but was weak as a younger tree and needs to be watched further. (Trials: Conant, Sierra Gold, Spanfelner)

94-019-29 (Vina x 67-013) (selected 2001): This tree was selected for its great yield, harvest 2 weeks before Chandler, and shell traits suitable for in-shell use. Kernel color has been excellent but shells have been dark in some cases. This tree has shown severe blight susceptibility when not sprayed but has been blight free in selection blocks. Tree is upright and vigorous. Nuts average 53% kernel and average kernel size is 8.0 g. (Trials: Noreen)

94-019-45 (Vina x 67-013) (selected 2001): A large, vigorous, branchy, and heavy cropping selection with moderate blight susceptibility and 8.0 g kernels. Leafing date is similar to Chandler but it harvests early to mid-season with nut traits suitable for in-shell use. Nuts yield 53% kernel. Color has been good but shrivel is a concern some years and harvest date may be spread out. (Trials: Conant)

94-019-85 (Vina x 67-013) (selected 2001): This selection could serve as an early Hartley with a harvest date similar to Payne and a Hartley-shaped nut. Kernel color has been good at Davis but shows problems at KAC and Chico. The shell remains thin and a bit rough but has relatively good strength, resembling Serr in this regard. Yield has been good, nuts contain 60% kernel with easy halves, and kernels average 8.4 g. Consider for release as an early variety. Watch the yield consistency. Also the leaves don’t abscise normally in some years. Continue to watch. (Trials: Bonturi)

94-020-5 (Vina x PI159568) (selected 2001): This was selected as a good yielding early inshell with excellent color. It averages 7.9 g kernels and has great shell strength. It harvests within a week of Payne and averages 51% kernel. The tree is large and vigorous. Watch for spreading or sweepy growth habit, consistency of yield, and stem end opening. (Trials: Stolp, Conant, Sierra Gold)

94-020-28 (Vina x PI159568) (selected 2005): This protandrous potential in-shell selection has Payne-time harvest date with good yield. The nuts contain 54% kernel and have a smooth, attractive shell that yields easy halves. The very plump kernels average 8.3 g with mostly good color but it has also had some bad years. Trees in selection blocks are still young. Watch for blanks and degree of lateral bearing

94-020-35 (Vina x PI159568) (selected 2001): This early in-shell selection harvests within a week of Payne with moderate blight and good yield. Shells are very solid and have excellent strength for in-shell use but are pointed and have a rough inner surface, which along with excellent fill, may impede halves. Kernels average 8.1 g but kernel color has not been consistently light. Nuts are long and oval like Sunland and the thick shell accounts for nuts averaging only 49% kernel. Tree appears to have a spreading weepy or willowy growth habit. (Trials: Stolp, Moore, Conant, Sierra Gold)

95-007-13 (77-012 x Serr) (selected 2001): This Serr seedling harvests close to Payne, has good yield and a solid, attractive shell but has not had good color the last several years. The amount of shrivel and strength of seals need to be watched further. Nuts yield 53% kernel and kernels average 8.3 g. New foliage has been noted to have a wilting appearance in late summer at some locations and it showed considerable mold at one location this year. Continue to evaluate it in selection blocks and grower trials. (Trials: Stuke, Conant, Scheuring)

*95-011-14 (67-013 x Chico) (selected 2001): This protogynous selection harvests with, or before, Payne and is characterized by great yield, excellent shell color and appearance, and mostly Chandler-like extra light kernels averaging 7.7 g. It may have sufficient shell strength for in-shell use but strength and seals should be watched and nut size is not large. Nuts yield 57% kernel with very easy removal of halves. Kernel quality and harvest date are excellent. This selection has shown some summer heat damage to the foliage and some summer nut drop. Watch for susceptibility to blight and summer heat stressed black nuts. (Trials: Sierra Gold, Scheuring, Conant, Moore, Bonturi, Spanfelner)

95-011-15 (67-013 x Chico) (selected 2001): Another selection with very good yield and kernel color, this tree has a solid shell and seal suitable for in-shell use but doesn’t have the shell appearance of its above sibling. The harvest date is about a week before Chandler and nuts average 52% kernel. Nuts are sometimes not well-filled and can have a thick leathery packing tissue. Kernels are not plump and average 7.4 g. but color has been mostly light to extra light. Blight is a serious concern when unsprayed. (Trial: Sierra Gold)

95-011-16 (67-013 x Chico) (selected 2003): This protandrous early in-shell selection harvests about a week after Payne and has large, light colored kernels that average 8.2 g. Nuts have very solid, attractive, oval shells that give 55% kernel. It has a tendency to tip shrivel. Yield is mostly good but watch the variation. (Trials: Scheuring)

95-011-22 (67-013 x Chico) (selected 2001): A high yielding selection with mostly light to extra light kernels and a mid-season harvest date. Nuts have 54% kernel with shell and seal strength suitable for in-shell use. Nut size is a concern. Kernels average 7.1 g but have declined noticeably as trees have aged. (Trials: Conant)

95-013-6 (Vina x Howard) (selected 2003): This tree was selected for its harvest date near Payne time, excellent kernel color, easy halves, and very solid shell suitable for in-shell use. It is a large vigorous tree. Kernels average 7.8 g in selection blocks but nuts average only 49% kernel. Hulls are thick so the nuts look bigger on the tree than they really are. Probable discard 2004.

95-013-12 (Vina x Howard) (selected 2003): Selected as an early in-shell possibility, this tree produces good yield close to Payne harvest time. The large, attractive nuts have a rounded Vina or Hartley shape and a very solid shell and yield halves easily but average only 47% kernel. Large, light kernels average 8.4 g. Consider as a lateral bearing, earlier harvesting Hartley replacement.

95-018-23 (Tulare x Chandler) (selected 2003): Excellent yield of mostly extra light kernels and harvests about a week after Payne. This is a short season selection that leafs after Chandler and has low blight. Shells are thin and have inadequate strength for in-shell use. Nuts yield 52% kernel and easy halves but fill is poor and kernels average only 7.0 g. (Trials: Scheuring, Carriere)

95-026-16 (Lara x Chico) (selected 2003): This protogynous selection harvests with Payne or earlier and has very good kernel color and little blight. Nuts yield 51% kernel and have solid shells and seals. Nuts have averaged only 7.2 g. Nut size and consistency of yield are concerns with this selection. Continue to watch in the selection blocks where nuts on young, less crowded trees are averaging 8.3g.

95-026-22 (Lara x Chico) (selected 2001): This protandrous tree harvests mid-season with a very strong shell and seal and good nut size. Kernels average 8.8 g and nuts yield 48% kernel. Kernels have generally been large, shiny, and light. Blight incidence has remained very low. The rough textured shells are very solid and can have inner roughness as well. If nuts are too well filled, kernels can be a bit difficult to remove in halves. This tree continues to have good nut size and yield. (Trials: Conant, Scheuring, Sierra Gold, Carriere, Taylor, Stuke)

96-013-13 (Howard x Chico) (selected 2003): This protogynous tree was selected for its excellent yield, light kernel color, good shell appearance, and mid-season harvest. It had better yield than Tulare trees around it as a seedling, an equivalent harvest date, and better color. The light colored, smooth, attractive shells have been solid and adequate for in-shell use most years. Nuts give 54% kernel but kernels average only 6.7 g and are not large on young trees in a selection block.

97-003-11 (Tulare x Mixed Chinese – Phase II) (selected 2004): Selected for its mid-season harvest, strong yield, Chandler leafing date, and large, plump, light colored kernels averaging 9.4 g. The large well-filled nuts yield 57% kernel. Shells are rough and seals should be watched.

97-003-23 (Tulare x Mixed Chinese – Phase II) (selected 2005): This is has a mid-season harvest. Nuts have a very attractive smooth and light colored shell and give 52% kernel. Kernels have excellent color and easy removal but have averaged only 7.2 g. Just beginning to bear in selection block.

97-003-40 (Tulare x Mixed Chinese – Phase II) (selected 2005): This is a protogynous mid-season selection with good yield. Nuts have a very solid strong shell and seal resulting in only 48% kernel. Color of the 7.4 g kernels has been good.

97-003-46 (Tulare x Mixed Chinese – Phase II) (selected 2005): This selection harvest very early, approximately with Payne and has large plump 8.6 g kernels with good color and easy removal. Shell strength and seal are probably not good enough or in-shell use. Nuts average 58% kernel.
