The Australian National Mango Breeding Program (NMBP) commenced in 1994 as a co-operative between four of the states and territories, and federal organisations. There are three hybrids that have been commercialised as a result of the project: NMBP 1201, NMBP 1243 and NMBP 4069.

Updates

New mango varieties from the National Mango Breeding Program have been planted in the Ali Curung area. Extending the mango harvest window with high quality mangoes is a key strategy for the Northern Territory (NT), and a trial of three new varieties being planted in the Barkly region is part of this strategy.

This project has a team of plant scientist from floral biologists, plant nutritionists, entomologists, pathologists, molecular diagnosticians in NT and Cambodia to optimise management strategies and increasing integrated pest management work in the region.

Mangoes are the NT's largest horticultural product, and the Territory is the country’s largest grower of mangoes.

Induction of mango flowering is sensitive to minimum and maximum temperatures in May–August (depending on the variety). Flowering is important for fruit set and critical for mango production.

The Department of Primary Industry and Resources is working with the Earth Systems and Climate Change Hub and the NT mango industry to use science-based climate change information to better understand the impact of the changing climate on mango production.

This is a PhD research project to investigate the molecular mechanisms behind flowering in mangoes, what genes are triggered and what proteins are expressed at the optimal time and whether these conditions can be manipulated.

This project aims to develop management practices with a view to manipulating the mango harvest window. It covers a number of different approaches including manipulating floral induction with growth promoting foliar sprays.

Another approach under investigation is the use of tip-pruning to influence bud development. This project takes advantage of the progressively cooler weather in Katherine to understand the effects of night temperatures on developing mango buds, potentially manipulating fruiting times, and improving productivity and profitability for mango farmers.

This project looks at improving the performance of Australian mangoes exported to the United States (US.), where they are positioned as a premium mango. With the long distance involved, there are risks of either delays or the fruit being subjected to incorrect temperatures in the supply chain which can impact on the premium quality necessary for this market.

DPIR, together with participating growers, exporters and Australian Mango Industry Association (AMIA), are trialling available monitoring technology in an effort to improve the temperature and location monitoring of Australian mangoes being exported to the U.S.

An ongoing research project looking at various aspects of fruit fly mitigation from population ecology, suppression trials, cage trials and oviposition studies. The main aim is to investigate the host status of hard mature mangoes at commercial harvest.

This project looks at management strategies to increase the quantity and quality of mango yields, whilst effectively mitigating loss of fertiliser applied nitrogen (N) to the environment. The research team will use stable isotopes to quantify plant N demand, soil supply and current practice N use efficiency (NUE) to develop best management practices for optimising N fertiliser use, including enhanced efficiency fertilisers (EEF). The project aims to maximise NUE in the Australian mango industry to increase productivity, profitability and good environmental management.

Investigating the possible contribution of nutrients towards the development of Resin Canal Disorder (RCD) by evaluating the composition or balance of nutrients in mango fruit.
