MALUMA HASS® : A NEW RELEASED CULTIVAR IN COMPARISON WITH HASS

BY

AA ERNST (ALLESBESTE NURSERY)

REG. NO. ZA 20043215

INTRODUCTION

HASS, A PREDOMINANTLY GUATEMALAN, WITH SOME MEXICAN GENES, WAS SELECTED IN 1926 BY MR RUDOLPH HASS AT LA GLABRA HEIGHTS, CALIFORNIA AS A CHANCE SEEDLING OF UNKNOWN PARENTAGE DUE TO ITS HIGH FLESH QUALITY, HIGHER YIELD AND LATER MATURITY THAN FUERTE. IN THE LAST 50 YEARS HASS HAS BECOME THE DOMINANT CULTIVAR GROWN IN SUBTROPICAL CLIMATES (NEWETT ET AL, 2002).

PLANT BREEDER’S RIGHTS (ZA 20043215) WAS GRANTED IN SOUTH AFRICA . REGISTRATION OF PLANT BREEDER’S RIGHTS FOR AUSTRALIA AND NEW ZEELAND IS PENDING. MALUMA HASS HAS BEEN APPROVED IN SOUTH AFRICA AS AN EXPORT CULTIVAR (END OF 2006).

MALUMA HASS®, ALSO A PREDOMINANTLY GUATEMALAN WITH SOME MEXICAN GENES, WAS SELECTED IN THE EARLY 1990’S BY MR DRIES JOUBERT AT MALUMA FARM, SOUTH AFRICA, AS A CHANCE SEEDLING OF UNKNOWN PARENTAGE DUE TO ITS SIMILARITY TO HASS. ALLESBESTE NURSERY EVALUATED THE VARIETY.

TO DRAW A COMPARISON BETWEEN MALUMA HASS® AND HASS

OBJECTIVE

MATERIAL AND METHODS

MALUMA HASS® WAS INTRODUCED INTO THE ALLESBESTE BREEDING AND SELECTION PROGRAMME (PHASE 2) DURING THE LATE 1990’S WHERE IT WAS SUBJECTED TO INTENSIVE TESTING

MALUMA HASS

TWO SEMI-COMMERCIAL TRIAL BLOCKS OF 1,5 HECTARE EACH WERE RESPECTIVELY PLANTED DURING MARCH 2001 WITH MALUMA HASS AND HASS GRAFTED ON CLONAL DUKE 7 WITH A 7 X 3,5 SPACING (408 PLANTS PER HA)

TRIAL BLOCKS WERE ESTABLISHED AT THE FARM HUMOR, TZANEEN IN THE LIMPOPO PROVINCE OF SOUTH AFRICA

THE CO-ORDINATES OF THE SITE ARE S 23º 44’25.0” E 30º 11’ 01.1” AT AN ALTITUDE OF 793 METRES

COMPARISONS WERE MADE WITH REFERENCE TO TREE, FLOWER AND FRUITING CHARACTE-RISTICS OF THE TWO CULTIVARS

CONCLUSIONS

MALUMA HASS® IS AN EARLY BEARING TRIANGULAR SHAPED THRIFTY UPRIGHT GROWING TREE WITH A NATURAL CENTRAL LEADER AND LATERAL BRANCHING, ALLOWING FOR GOOD LIGHT PENETRATION AND HIGH PRODUCTIVITY

MALUMA HASS® SUCCESSFULLY RELEASED FROM THE BREEDNG AND SELECTION PROGRAM OF ALLESBESTE NURSERY, SOUTH AFRICA

COULD BE CONSIDERED FOR HIGH-DENSITY PLANTINGS

MALUMA HASS® IS PRECOCIOUS, WITH A HIGH AND CONSTANT BEARING PATTERN ANNUALLY

SIGNIFICANTLY OUTPERFORMS HASS, ON A PLANT DENSITY OF 400 TREES PER HECTARE, ON PRODUCTION AND INCOME

PRODUCTIVE WITHOUT THE USE OF GROWTH RETARDANTS WITH SUBSTANTIAL SAVING IN PRODUCTION COST

MALUMA HASS® HAS A BETTER COUNT DISTRIBUTION THAN HASS

BEING AN EARLY FRUITING CULTIVAR IT CAN SUCCESSFULLY EXTEND THE HASS SEASON BY ONE MONTH

ON FRUIT APPEARANCE, QUALITY AND TASTE MALUMA HASS COMPARES VERY FAVOURABLE WITH HASS

ACCEPTED BY TESCO (A LEADING U.K. SUPERMARKET) FOR ITS RIPE-AND-READY PROGRAMMES

FULL EXPORT CULTIVAR STATUS IN SOUTH AFRICA SINCE END 2006 - EXPORTS WELL

MALUMA HASS IS EITHER RESISTANT OR TOLERATES THE MOST IMPORTANT FRUIT DISEASES AND DISORDERS

ALLESBESTE NURSERY HOLDS THE PLANT BREEDER’S RIGHTS FOR MALUMA HASS® UNDER REGISTRATION NUMBER ZA 20043215

THE REGISTRATION FOR PLANT BREEDER’S RIGHTS IS PENDING IN NEW ZEALAND AND AUSTRALIA
