These varieties also offerthe same agronomic benefits as Kaspa(eg semi-leafless plant type, improvedlodging and pod shattering resistance)and marketing benefits (round shape,improved milling quality).Of the two, PBA Gunyah generally offersthe most reliability across current fieldpea growing areas in South Australia, andwas 5 percent higher yielding than PBATwilight in 2010.Adoption of these varieties will alsoprovide the opportunity to eliminateParafield contamination in Kaspa crops.Yarrum equal topped the NVT and PBAtrials for the fourth year in a row.Yarrum is a late flowering, high yielding,powdery mildew resistant dun type pea,with improved resistance to virus.Long term yields show Yarrum hasconsistently performed well across thestate, and provides an alternative to Kaspain areas where powdery mildew andviruses are regular problems.However Yarrum does not have thesame round seed and shatter resistancequalities as Kaspa, PBA Gunyah and PBATwilight.Kaspa performed relatively well in 2010,performing similarly to the site mean atall sites. It yielded higher than Parafieldat 8 of the 11 NVT and PBA sites.Kaspa remains the preferred variety inhigh rainfall areas not prone to bacterialblight, however alternative varietiesshould be considered if they provideregional advantages.OZP0703 is a high yielding earlyflowering dun variety with greatertolerance to bacterial blight (pv syringae)than current pea varieties.It averaged 99 percent of site meanyield across all sites in 2010. OZP0703performed 10 percent higher than Kaspain 2009 and 17 percent higher in 2008across all sites, and shows a three percentyield advantage over Kaspa long term.This demonstrates its suitability acrosssites and seasons, not necessarily affectedby bacterial blight. OZP0703 is expectedto be released by AWB Seeds for 2012sowings.More information:Mick Lines, (08) 8842 6264michael.lines@sa.gov.au2 0 1 1 SARDI Crop Harvest Report < 27
