M7 is a very early maturing navel

Mutation discovered in Autumn 2004 on a Navelina (clone 7.5) tree in the orchard of:

Chislett Developments Pty Ltd Kenley, Victoria, Australia.

Australian PBR granted: 2005/185USA Plant Patent: US PP18,774P2

M7 Navel



Background

● Mutation first noticed when M7 had full colour and Navelina was light green on 02-May-2004

● Advanced colour around 4 weeks earlier than Navelina

● Very high brix 13.07 when Navelina was 9.94 on 18-May-2004

● Certified by Auscitrus to be free of any viruses in March 2006.


Note: The true to type Fukumoto variety is not available in Australia for comparison about maturity timing is very similar to Navelina


Outstanding Characteristics

● Earlist Colour ● Round fruit shape● Early Internal Maturity● Very high brix● Extended harvest period● No albedo breakdown● Firmer rind than Navelina throughout harvesting period

Observations made at Kenley, Victoria, which is a late citrus growing area



Outstanding Characteristics

● Late hanging● Vigorous and a distinctive foliage● Medium to small and distinctive external navel ● Small internal navel● Early production, good yields and fruit size● Good compatibility with all rootstocks

External Navel

● Medium to small - similar to Navelina

● Distinctive with slight lines radiating outwards from the navel.



Internal Navel● Significantly smaller than Navelina 7.5

Photos taken August 25, 2006 at Dareton Research Station



Colour● More even over tree and 4 weeks earlier than Navelina, gas colouring

possible early April (October NH).● M7 on the 5-Apr-05 had better colour than Navelina on the 28-Apr-05.● Individual fruit colour more uniform than Navelina.● Intensity of colour similar to Navelina when fully developed.



Fruit Shape

● Completely round fruit



Internal Quality ● Maturity 3 weeks earlier than Navelina● Maintains acid levels of 0.7grams of citric acid per

100 ml of juice on 06-September-2005 (March NH)● Exceptional eating quality due to higher brix (13º

plus) and balanced acid● High flavour intensity – much better eating quality

than navelina



Internal Quality● Potentially good juicing

yields

● More advanced and intense flesh colour than Navelina

● Limonin levels to be determined and expected to be relatively low like Navelina


Note: Fukumoto shown is not the same variety existing in other countries

Internal Quality California Standard - proposed for M7TM 105 - 170

California Standard = 16.5(Brix-4TA)

2011 Season (2 weeks late)

California Standard

M7 Navelina

15/04 86.5 65.3

29/04 116.5 94.7

(Kenley – late maturing area)



Rind Quality

● No sign of albedo breakdown or creasing ever observed.

● Very strong and firmer than Navelina throughout harvest period.



Leaf Shape● Length to width ratio

significantly lower and petiole wing more pronounced compared to Navelina.

● Leaf also has a distinctive undulation



Foliage● More upright and open

than Navelina allowing more light penetration facilitating colour development

● Less pruning needed



Tree and Yields● Very vigorous tree. Fast growing and

early cropping

● Good production – 15 tonne/ha from 3.5 year old trees (1000 trees/ha)

● Good fruit size, probably better than Navelina



Protectability● M7 is easy to protect.● Any fruit in the market before Navelina has to

be M7.● Round fruit shape with distinctive navel end

marks.● Easy to identify the variety in the field due to

the distinctive leaf shape and foliage.



Harvest period● Harvest possible 3 weeks earlier than Navelina

● Kenley (late maturity area) juice 40%, brix 10o, ratio 8.0:1 by early to mid April (October NH)

● Fruit - firm and good condition on tree for minimum 4 months (firmer than Navelina at all stages)

● Acid levels maintained above 0.75% for at least 4 months

● No fruit drop without 2,4D up to the end of August, obvious drop on Navelina

Harvested Kenley from 3.5 year old unpruned trees

TestimonialHi Guys,Here are the results for the samples Greg sent in.The M7 was very impressive, I tested 6 fruit.With the other 2, I cut one up and left the other whole and showed Bill, Perry, Ferdi and Gerome (Holman Fresh). All were very impressed, Gerome especially – he said he loved the variety and couldn’t believe the taste, colour, shape and rind quality. He said it needs a sexier name and thought Mara Mara could be a good one! I’ll let you think about that one GregKind regards, Mara Milner
