Description

ACKNOWLEDGMENT OF GOVERNMENT SUPPORT
This invention was made with government support under Specific Cooperative Agreement No. 58-5358-4-025 awarded by the United States Department of Agriculture. The government has certain rights in the invention.
Botanical denomination: Corylus avellana cultivar.
Variety designation: ‘Burgundy Lace’.
BACKGROUND
The present disclosure relates to a new and distinct cultivar of Corylus plant, botanically known as Corylus avellana, and hereinafter referred to by the name ‘Burgundy Lace’.
The new Corylus resulted from a controlled cross of female parent OSU 562.034 (unpatented)×OSU 562.062 (unpatented) made in 1998 to create a new ornamental cultivar (FIG. 1). OSU 562.034 is from a cross of ‘Cutleaf’×VR6-28 (unpatented), and OSU 562.062 is from a cross of ‘Cutleaf’×Redleaf #3 (unpatented). The grandparent ‘Cutleaf ’(unpatented) is known as Corylus avellana f. heterophylla, for which the form names laciniata, urticifolia, quercifolia and incisa pinnatifida are also used. VR6-28 is from a cross of ‘Riccia di Talanico’בGasaway’, and carries a dominant allele for a very high level of resistance to eastern filbert blight (EFB) from ‘Gasaway’ (unpatented). OSU 562.062 and Redleaf #3 carry a dominant allele for leaf anthocyanin. Redleaf #3 is an open-pollinated seedling of ‘Barcelona’ (unpatented). The pollen parent is believed to be the Redleaf ‘Rode Zeller’ (syn. ‘Rote Zellernuss’) (unpatented).
Hybrid seeds from the controlled cross were harvested in August 1998, stratified, and the resulting seedlings grown in a glasshouse during the summer of 1999. Seedlings that combined red leaf color and the ‘Cutleaf’ trait were preferred, and 38 of the 40 seedlings planted in the field in October 1999 combined these two traits. ‘Burgundy Lace’ was discovered and selected as a single plant within the progeny of the stated cross-pollination in a controlled environment in Corvallis, Oreg., USA. The new variety was originally assigned the designation OSU 954.076, which indicates the row and tree location of the original seedling.
The new cultivar was asexually reproduced by rooted suckers annually for five years (2005, 2006, 2008, 2011 and 2013) in Corvallis, Oreg. The unique features of this new Corylus are stable and reproduced true-to-type in successive generations of asexual reproduction.
SUMMARY
The following traits have been observed and are determined to be the unique characteristics of ‘Burgundy Lace’. These characteristics in combination distinguish ‘Burgundy Lace’ as a new and distinct cultivar:
    • 1. Rich dark burgundy-colored developing leaves and burgundy-colored fully expanded leaves during the spring and summer.
    • 2. Deeply dissected leaves.
    • 3. Burgundy color of the catkins and leaf buds.
    • 4. Moderate vigor and upright-spreading plant habit.
    • 5. Resistance to eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller.
    • 6. Presence of random amplified polymorphic DNA markers 152-800 and 268-580 in DNA of ‘Burgundy Lace’ amplified by the polymerase chain reaction. These two markers are linked to a dominant allele for resistance to eastern filbert blight from the cultivar ‘Gasaway’ (unpatented).
    • 7. Expression of incompatibility alleles S6 and S20 in the styles.
    • 8. Catkins that are abnormal and small, and produce little pollen.
    • 9. DNA fingerprints of ‘Burgundy Lace’ differ from ‘Cutleaf’ at 14 of 24 microsatellite marker loci. Additional DNA fingerprints of ‘Gasaway’ and ‘Rode Zeller’, which are ancestors of ‘Burgundy Lace’, and 12 other reference cultivars, are shown in Table 7.
‘Burgundy Lace’ is well-suited to the ornamental market. ‘Burgundy Lace’ combines red leaf color, deeply dissected leaves, and resistance to eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. Comparisons in two trials conducted in Corvallis, Oreg., plants of ‘Burgundy Lace’ in the guard rows differed from plants of the Corylus avellana cultivars ‘Barcelona’ (unpatented) and ‘Jefferson’ (unpatented), and other cultivars and selections of Corylus avellana known to the Inventors primarily in nut size, nut shape, kernel percentage (ratio of kernel weight to nut weight), frequency of defects (blank nuts, moldy kernels, twins, etc.), time of pollen shed, time of nut maturity, length of the husk or involucre, and plant size.
The tree is moderately vigorous, similar in size to ‘Jefferson’, and has a desirable upright-spreading growth habit that should be easy to manage in a landscape setting. The nuts are small and the kernels are edible, but nut yields are low and quality is not suitable for the kernel market. ‘Burgundy Lace’ has far fewer blanks (shells lacking kernels) than ‘Cutleaf’. ‘Burgundy Lace’ has intermediate ratings for bud mite (primarily Phytoptus avellanae Nal.), similar to ‘Clark’. Like its grandparent ‘Cutleaf’, catkins of ‘Burgundy Lace’ shed very little pollen. Pollen shed and female receptivity are late.
DNA markers and field observations indicate that ‘Burgundy Lace’ has resistance to eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. The resistance is conferred by a dominant allele from ‘Gasaway’. EFB is now present throughout the Willamette Valley and in the eastern USA where it naturally occurs on the wild American hazelnut (C. americana), but causes little damage. Pruning to remove cankers and fungicide applications are currently used to manage the disease in susceptible cultivars. Thus, ‘Burgundy Lace’ is suitable for planting in areas with high disease pressure.

Plants of the new Corylus are moderately susceptible to bud mites (Phytoptus avellanae Nal.), while plants of ‘Tonda Gentile delle Langhe’ are highly susceptible, and plants of ‘Barcelona’ are highly resistant.
  • Temperature tolerance: Plants of the new Corylus have been observed to tolerate temperatures from −21 to 38° C. in the field in Corvallis, Oreg.
  • Comparative data:
      • Tree size, growth habit, yield, and yield efficiency.—Tree sizes in the trials were estimated by measuring trunk diameters 30 cm above the soil line, at the end of the 7th growing season (December 2013 and 2014, respectively). Trunk cross-sectional area (TCA) was calculated from trunk diameter. Trees of ‘Burgundy Lace’ are moderately vigorous, similar in size to ‘Jefferson’ (Tables 1 & 2). In previous trials, TCAs of ‘Jefferson’ and ‘Lewis’ were about 70% of ‘Barcelona’. Their upright-spreading growth habit of ‘Burgundy Lace’ trees should be easy to manage in a landscape setting. In the 2007 trial, total nut yield per tree averaged 10.04 kg for ‘Burgundy Lace’, which is less than the other four cultivars (Table 1). Nut yield efficiency for OSU 954.076 (0.122 kg/cm2), which adjusts for differences in tree size, was similar to ‘Felix’ (0.133 kg/cm2), and lower than ‘Jefferson’ (0.299 kg/cm2), ‘Santiam’ (unpatented) (0.267 kg/cm2) and ‘McDonald’ (0.245 kg/cm2). In the 2008 trial, total nut yield per tree averaged 11.39 kg for ‘Burgundy Lace’, which is more than ‘Eta’ (unpatented) (7.78 kg) but less than the other 13 genotypes (Table 2). Nut yield efficiency for OSU 954.076 (0.134 kg/cm2), which adjusts for differences in tree size, was similar to the pollinizer ‘Theta’ (unpatented) (0.149 kg/cm2), higher than ‘Eta’ (0.100 kg/cm2) and lower than ‘Jefferson’ (0.292 kg/cm2) and the others in the trial. Although ‘Burgundy Lace’ would generally not be planted for nut production, its nuts show a very low frequency of defects (Tables 3 & 4). In the 2007 trial, nut weight was 1.72 g and kernel percentage was 44.1%, the latter being similar to ‘Barcelona’ (typically 43%). The amount of fiber on the pellicle was rated on a scale of 1 (no fiber) to 4 (heavy fiber) (Table 5). The rating for ‘Burgundy Lace’ (2.8) was similar to ‘Jefferson’ (3.0) and indicates a moderate amount of fiber. Kernel blanching, or ease with which the pellicle can be removed with dry heat followed by rubbing, was rated on a scale of 1 (complete pellicle removal) to 7 (no pellicle removal). The rating for ‘Burgundy Lace’ (6.6) indicates that very little of the pellicle is removed by dry heat. Very few moldy kernels were observed in ‘Burgundy Lace’ (0.5%), in striking contrast to ‘Santiam’ (17.3%) (Table 3). The results from the second trial (Table 4) were nearly identical: nut weight 1.71 g, kernel percentage 44%, fiber rating 2.8, blanching rating 6.6, with 87.5% good nuts and very few defects. The kernels, raw or roasted, are not attractive.
      • Nut maturity date.—Most nuts of ‘Burgundy Lace’ are borne in clusters of two, in husks about half as long as the nuts. The nuts are slightly long and compressed. The husks open as they dry at maturity, and about 98% of the nuts fall free of the husk. When mature, the shells are medium brown in color and have pubescence at the apical end. Harvest date is estimated to be three days before ‘Barcelona’.
      • Incompatibility and pollinizers.—‘Burgundy Lace’ has incompatibility alleles S 6 and S20 as determined by fluorescence microscopy. Both alleles are expressed in the females, but only S6 is expressed in the pollen because of dominance. By convention, alleles expressed in the pollen are underlined. The trees set a moderate number of catkins. The catkins are abnormal and small, as are those of ‘Cutleaf’, and shed very little pollen. For practical purposes, ‘Burgundy Lace’ is male-sterile, although collection of a handful of catkins can give a trace of pollen. Time of pollen shed and female receptivity were observed weekly from December 2012 to March 2013 and December 2013 to March 2014 (FIG. 2). Female flower receptivity of ‘Burgundy Lace’ is late and about one week earlier than ‘Cutleaf’ and four weeks later than ‘Barcelona’. Time of catkin elongation of ‘Burgundy Lace’ is also late and about three weeks earlier than ‘Cutleaf’ and three weeks later than ‘Barcelona’. Date of leaf budbreak is about one week later than ‘Cutleaf’ and 2.5 weeks later than ‘Barcelona’. Pollen of the following EFB-resistant cultivars is compatible on females of ‘Burgundy Lace’: ‘Yamhill’ (S 8 S26), ‘Dorris’ (S 1 S 12 ), ‘McDonald’ (S2 S 15 ), ‘Wepster’ (S 1 S2), ‘York’ (S2 S 21 ), ‘Gamma’ (S2 S 10 ), ‘Jefferson’ (S1 S 3 ), ‘Felix’ (S 15 S 21 ) and ‘Theta’ (S 5 S 15 ). Because females of ‘Burgundy Lace’ are receptive late in the season, the late-shedding pollinizers ‘Felix’ and ‘Theta’ are most effective.
      • Pests and diseases.—Based on DNA marker data, ‘Burgundy Lace’ has a very high level of resistance to EFB conferred by a dominant allele from ‘Gasaway’, so fungicide applications are not needed. RAPD markers 152-800 and 268-580 that flank the resistance allele in ‘Gasaway’, are present in ‘Burgundy Lace’. Trees of ‘Burgundy Lace’ have not yet been challenged with the EFB pathogen in glasshouse or structure inoculations. Susceptibility to bacterial blight caused by Xanthomonas campestris pv. corylina has not been quantified, but none of the three trees in the two trials were affected. Nevertheless, copper sprays to minimize damage from this pathogen can be performed. Susceptibility to big bud mite (primarily Phytoptus avellanae Nal.) was rated in the 2007 trial (Table 3) after leaf fall once per year for five years (December 2009-2013). The scale was from 1 (no blasted buds) to 5 (many blasted buds). The average rating for ‘Burgundy Lace’ (3.0) is similar to that for ‘Clark’ and lower than for ‘Cutleaf’ (4.0), which was rated one year at the Smith Farm and three years (2000-2002) at the nearby USDA National Clonal Germplasm Repository. In the 2008 trial, the rating for ‘Burgundy Lace’ (3.1) is the same as for the moderately susceptible ‘Clark’ (3.0). The number of blasted buds for ‘Burgundy Lace’ is lower than ‘Cutleaf’ and sprays should not be necessary to control this pest. The other check cultivars in the two trials had lower bud mite ratings.
      • Propagation.—‘Burgundy Lace’ was propagated by tie-off layerage of the suckers of the original seedling tree in late June over five years (2005, 2006, 2008, 2011 and 2013). On average, 22 suckers were layered, with rooting rated good on 11 and fair on 7, poor on 3 and no roots on one. The size (caliper) was rated as medium to large in most years. Layers are moderately vigorous and root well, but have lower vigor and caliper than those of ‘Jefferson’ and ‘Barcelona’.
      • DNA fingerprinting.—Primers used are shown in Table 6, and results shown in Table 7. ‘Burgundy Lace’ differs from ‘Cutleaf’ at 14 of 24 loci.
