Faba Bean FABA BEAN There are varying sizes of faba bean seeds and colour that are identified by different names. Small-seeded types (Vicia faba var. minor) may be called faba bean or tickbean and are commonly used for human consumption and animal feed. Medium and large size seed types (V. faba var. major) may be called broad bean and are used more commonly as a dry broad bean or as a green bean. Faba beans grown in Australia are predominately exported for the human consumption export market to the Middle East. These markets demand high visual quality standards to meet market specifications in a relatively small world export market. Australia competes with the European Union, particularly the United Kingdom and France, for a share of the 300,000 tonne Middle East market. Middle Eastern countries use faba bean for human consumption as part of the staple diet. It is referred to as ‘foul’ which is equivalent to bread as a staple in Australian diets. The market demand for the Middle East is consistent and if there is a surplus of product produced in Australia, expect to see a price decrease. REVIEW OF 2014 Season The good opening rains, sunny days and mild growing conditions into winter gave faba beans an excellent start. In the latter half of winter cooler dry conditions and frosts slowed growth but also substantially reduced aphid populations. With dry conditions and strong winds in early spring faba beans failed to realise their potential. A late frost in November caused flowers to abort and pods to burst in the southern Wimmera and south west regions. Faba beans in the North East did well with excellent quality and average to above average yields. Those on irrigation also fared well. Some crops in the northern Mallee on stored moisture from summer rain performed well as they matured before the hot weather. Elsewhere yields varied from below to well below average. Quality was generally good overall. The total area sown to faba bean is continuing to see a resurgence, with improved understanding of agronomy and disease management along with excellent commodity prices. In recent years some growers using wide row, no-till cropping have found faba beans profitable as the lower pods are able to fill properly. Disease and insects Rust and chocolate spot were observed over late winter and treated with fungicides, but as conditions dried off fungal diseases did not develop. A change in the ascochyta pathotype in the mid-north of South Australia this year meant some resistance in the faba bean genetics was overcome, but this pathotype did not reach Victoria during 2014. The warm start to the growing season increased the number of insects and the potential for viruses. Again frosts and drier conditions meant this did not continue except for 68 Victorian Winter Crop Summary 2015 some sporadic insect damage. However there could be some seed staining from Pea seedborne mosaic virus. LOOKING FORWARD TO 2015 New varieties PBA Samira is the first of a new series of high yielding faba beans to be released. These lines are expected to offer yield advantages of 5-10% in most regions. Samira is suited to the longer season environments and is expected to replace Farah and Fiesta. Pod set Sowing early does not necessarily result in greater pod set, but wider row spacings may help sunlight to penetrate the canopy and increase podding. Sow in areas away from canola paddocks to avoid bees being diverted to the stronger odour of the canola. Sow away from field pea crops to minimise aphid transmission of viruses, particularly pea seed borne mosaic virus (PSbMV). Disease Growers need to be prepared for a shift in virulence as the new strain of ascochyta spreads from South Australia to Victoria. All varieties should be monitored carefully. If 2015 provides good sowing conditions and adequate rain during the grain fill period, it is highly recommended that growers spray bean crops for disease control. The 6-8 week and 15 week growth stages are the important timing to minimise ascochyta blight, cercospora leaf spot and chocolate spot in order to maximise yield and harvest disease free seed. Prompt harvest when the crop is initially ripe is also important to retain grain quality. Anecdotally, Aquadulce and PBA Kareema rated better for chocolate spot resistance compared to Nura and Farah. All current varieties are susceptible to cercospora leaf spot. MORE INFORMATION www.nvtonline.com.au Detailed NVT trial results and links to variety information.

Broad bean - AQUADULCE Tall late flowering broad bean with some tolerance to waterlogging as well as iron and manganese deficiencies. Best suited to high rainfall districts (>450mm). MS to ascochyta blight, chocolate spot and rust. Released 1982. Faba Bean Broad bean - PBA KAREEMA PBA Kareema is a direct replacement for Aquadulce. PBA Kareema requires a long growing season similar to Aquadulce and rainfall greater than 450mm. It is RMR to ascochyta blight and MS to chocolate spot. PBA Kareema is only recommended for the south west region of Victoria. Released 2009. PGG Wrightson Seeds. EPR $4. Faba bean - PBA RANA Relatively late flowering and maturing variety suited to higher rainfall, long season regions. Seed is larger than current varieties and is considered high quality by the major Egyptian market. Resistant to both foliar and seed ascochyta blight with improved resistance to chocolate spot compared to Fiesta and Farah. Seednet. EPR $3.50. Faba bean - FARAH Farah is similar to Fiesta but has good ascochyta blight resistance (both leaf and pod), which reduces grain staining from ascochyta at harvest. Farah yield is similar to Fiesta across southern Australia and performs best in medium rainfall environments. Released 2004. Heritage Seeds. EPR $3. Faba bean - PBA SAMIRA A new higher yielding variety with wide adaption. Excellent disease resistance and later flowering mean it can take advantage of late rainfall in longer season environments. Seed is a similar size to Fiesta and Farah and is suited to Middle East markets. Excellent ascochyta resistance and improved resistance to chocolate spot and rust compared to Fiesta and Farah. Developed by PBA (as AF05069-2). Released 2014. Seednet. EPR $3.50. Faba bean - FIESTA VF A medium sized bean, Fiesta has good yields and wide adaptation throughout southern Australia. It has good seedling vigour and is of medium height. Fiesta is MRMS to foliar ascochyta blight, MS to seed ascochyta and S to chocolate spot. Released 1998. POTENTIAL NEW VARIETIES from Pulse Breeding Australia. Faba bean – AF05095-1 A new higher yielding breeding line. A later flowering and maturing variety that has performed very well in longer season environments. Seed is larger than Fiesta and Farah and similar to PBA Rana and should be suited to Middle East markets. Good overall response to diseases, provisionally rated as resistant to Ascochyta and chocolate spot. Developed by PBA. Release anticipated in time for the 2016 growing season. Seednet. EPR to be determined. Faba bean - NURA Nura is shorter than Fiesta and Farah and less likely to lodge, however the bottom pods are closer to the ground. RMR to ascochyta blight, MS to chocolate spot and rust. Nura needs to be sown early as it flowers about seven days later than Fiesta, but it matures at a similar time. Released 2005. Seednet. EPR $3.
