Australian Almond Variety – Maxima
Maxima is a highly spur bearing tree that is suited to planting in traditional or higher density orchards. The hull flares away from the shell in a ‘banana’ fashion and has a very large kernel that may be suited to markets where large size attracts premium pricing.
- Cross-pollination needed
- Spur bearing
- Late pollinator for Nonpariel
- Very large kernel size
|Branching density||Medium high|
|Nut location||Spurs and one year old wood|
|Flowering time||Medium, full bloom 4 days later than Nonpareil|
|S compatibility genotype||S3S8|
|Compatible Pollinators||Nonpareil, Carmel, Monterey, Capella, Wood Colony, Mira|
|Length of flowering||Medium, approx. 3 weeks|
|Cropping capacity||Very high|
|Cropping regularity||Good. Little to no alternate bearing|
|Bacterial spot tolerance||Initial screening resulted in tolerance equal to Nonpareil.**|
|Harvest season||Early mid|
|Husking ease||Good. Hull is easily separated from shell|
** Initial Bacterial Spot testing was conducted on the leaves only. Further assessment is currently being conducted on the fruit and leaves following strong visual symptoms in one of the commercial trials during the 2017-18 growing season.
|Kernel size||Very large (2.05 g)|
|Double kernels||No doubles|
|Kernel appearance||Attractive, skin colour light and bright|
|Kernel composition||Oil 62.4%; oleic acid 59.9%; Vitamin E 51.7 mg/100g oil|
Maxima is a semi-hard shelled variety that has consistently out yielded Nonpareil by 20% over eight years of yield assessments. It has superior fruit characteristics with a semi-hard shell, fully sealed shell and very large, sweet tasting, lightly coloured kernel. Maxima’s two main outstanding qualities are its early precocity to crop on spur wood and its large kernel size, approximately 2 grams. The full enclosed shell seal provides protection against insect and bird damage, whilst the hull detaches easily at harvest. The growth habit is slightly spreading similar to Nonpareil but bears mostly on spur growth. Maxima can be used as a late pollinator for Nonpareil, replacing Carmel and Wood Colony. Maxima needs cross pollination to successfully bear fruit.
