7 © 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: 2005/185 USA Plant Patent: US PP18,774P2 M7 Navel © 2012

8 © 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 when Navelina was 9.94 on 18-May Certified by Auscitrus to be free of any viruses in March © 2012 Note: The true to type Fukumoto variety is not available in Australia for comparison about maturity timing is very similar to Navelina

9 © 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 © 2012

10 © 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 Observations made at Kenley, Victoria, which is a mid to late growing area © 2012

11 © External Navel Medium to small - similar to Navelina Distinctive with slight lines radiating outwards from the navel. © 2012

12 © Internal Navel Significantly smaller than Navelina 7.5 Photos taken August 25, 2006 at Dareton Research Station © 2012

13 © 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. © 2012

14 © Fruit Shape Completely round fruit © 2012

15 © 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 © 2012

16 © 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 © 2012 Note: Fukumoto shown is not the same variety existing in other countries

17 Internal Quality California Standard - proposed for M7 TM California Standard = 16.5(Brix-4TA) 2011 Season (2 weeks late) California Standard M7Navelina 15/ / (Kenley – late maturing area) © 2012

18 © Rind Quality No sign of albedo breakdown or creasing ever observed. Very strong and firmer than Navelina throughout harvest period. © 2012

19 © Leaf Shape Length to width ratio significantly lower and petiole wing more pronounced compared to Navelina. Leaf also has a distinctive undulation © 2012

20 © Foliage More upright and open than Navelina allowing more light penetration facilitating colour development Less pruning needed © 2012

21 © 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 © 2012

22 © 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. © 2012

23 © Harvest period Harvest possible 3 weeks earlier than Navelina Kenley (late maturity area) juice 40%, brix 10 o, 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 © 2012

32 Testimonial Hi 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 couldnt believe the taste, colour, shape and rind quality. He said it needs a sexier name and thought Mara Mara could be a good one! Ill let you think about that one Greg Kind regards, Mara Milner © 2012
