Mandarin tree named ‘950’

Abstract

A new mandarin hybrid tree particularly distinguished by having dense foliation; bearing fruit that are attractive in appearance with excellent eating quality; has lateral branching with lower angle plant habit; a round tree shape; and nearly seedless fruit is disclosed.

Description

Genus and species: Citrus reticulata.

Variety denomination: ‘950’.

BACKGROUND OF THE NEW PLANT

The invention relates to a new and distinct variety of mandarin Citrus reticulata hybrid tree named ‘950’. ‘950’ is a very vigorous tree that produces nearly seedless fruit and has a non-pungent peel oil. ‘950’ usually ripens from the end of November to late January in central Florida.

‘950’ originated as a single plant from a cross conducted in March of 1991 in Lake Alfred, Fla., between ‘LB8-8’ (unpatented) and ‘Fortune’ (unpatented). Parent ‘LB8-8’ is a hybrid of a ‘Clementine’ and ‘Minneola tangelo’, and parent ‘Fortune’ has been reported to be a hybrid of ‘Algerian Clementine’ and unknown. Asexual propagation by budding in Lake Alfred, Fla. has shown that all distinguishing features and characteristics of the fruit and tree remain true to the original seedling tree and are in firmly fixed form.

Plant Breeder's Rights for this cultivar have not been applied for. ‘950’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The new and distinct variety of mandarin hybrid (tangerine) tree bears fruit that ripens from the end of November to late January in central Florida. The trees usually bloom around March to early April in central Florida, depending on the season, and they grow in a moderately vigorous manner. The fruit of ‘950’ trees are nearly seedless, tend to be a bit smaller in diameter (between 55 mm to 65 mm) than fruit of ‘LB8-8’, have a round shape, moderate acidity, an orange color internally and an orange-red color externally, and have excellent eating quality. The fruit are juicy, but can be easily peeled.

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Florida.

• • 1. Dense foliation;
  • 2. Bearing fruit that are attractive in appearance with excellent eating quality;
  • 3. Lateral branching with lower angle plant habit;
  • 4. Round tree shape; and
  • 5. Nearly seedless fruit.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘950’. The present botanical description was taken from an individual 10-year-old tree grown on its own roots at the Riley research block near Haines City, Fla. The colors (except those in common terms) are described from R.H.S. Colour Chart published by The Royal Horticultural Society in London (second edition), in association with the Flower Council of Holland.
