Department of Primary Industry and Fisheries 140 SUBPROGRAM: Citrus PROJECT: Improved Citrus Products for the NT - Evaluation of Mandarin Cultivars in the Top End - Katherine Project Officers: J. Bright, R. Renfree and A. Maddern Location: KRS Objective: Identify cultivar/rootstock combinations suitable for both existing and potential markets when grown in various regions of the NT. Help growers to optimise their returns through the production of fruit of the required cultivar and quality for the intended market. Early cultivar assessments of mandarin production in Katherine were not encouraging given poor management, which resulted in low flowering and low erratic yields. Recent trials have shown promising results on other citrus with modification of management, using moisture stress to enhance flowering and fruit thinning to increase yield and individual fruit size. The NT citrus industry has requested that mandarin cultivars be assessed again so as to increase the available options to growers so as to produce fruit that has the widest market appeal. Since the last assessments, a number of new cultivars and cultivars from climates similar to Katherine have been made available. There is virtually no Australian production of mandarin/tangor types during the months of January, February and March. Early maturing cultivars at Katherine could be harvested in February and March. This trial will focus on 26 cultivars, nine of which are bred by CSIRO. The Imperial and Murcott have been included in the trial as reference cultivars. Method: Table 1.

Treatments are single tree plots replicated four times. Other mandarin material sourced as seed from various countries will be planted as guard trees.
