Tropical Pulses for Queensland
Tropical Pulses for Queensland is a joint project between the Queensland University of Technology and the Queensland Government, Department of Agriculture and Fisheries. The following projects fall under the unbrella of the Tropical Pulses for Queensland project:
- Chemical pre-treatment as a novel strategy to enhance stress tolerance and growth rates
- Generation of elite chickpea varieties for enhanced stress tolerance and resistance to Botrytis cinera
- Iron biofortification of chickpea
- Mungbean nested association mapping population
- Optimisation of Genotype x Environment x management interactions for increased pulse yield
The associated dataset 'Next generation mungbean SNP markers' and database are products of the Mungbean nested association mapping population project.
The data enables users to perform simulation modelling to further the understanding and prediction of genetics, environment and management interactions to improve the stability of tropical pulse production in Australia. The cultivation of tropical pulses such as chickpea and mung bean is experiencing price and yield booms and the industries are worth approximately $441 and $80 million, respectively in Queensland alone. Mungbean is particularly poised to increase production over the next few years.
The information from the nested association mapping population will contribute significantly to this boom. For the first time, mungbean researchers and breeders will be able to see recombination patterns and frequency, why some traits are always inherited together and why they may not be able to access certain regions of the genome through conventional breeding methods. This global resource will aid in the study and breeding of complex traits such as disease resistance, phenology, drought and heat stress at flowering.
Pulse crops include chickpea, lentils, mung bean, cowpeas and beans grown for their dry edible seeds high in protein and fibre, but low in fat. Pulses provide some of the world’s most economical sources of protein for food and feed. These proteins are high in the essential amino acids lysine and methionine, making them nutritionally complementary to the cereals that lack both these amino acids. While growing pulses has natural advantages such as increasing soil nitrogen content, increasing tropical pulse production has some inherent challenges.
Increasing climate variability and change are major risk factors, as are the increasing incidences of pests and diseases. In a recent study, the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) forecasted that agricultural production could fall by as much as 19 per cent by 2050 with Australia projected to be one of the most adversely affected regions in terms of reductions in agricultural production and exports.
