AAC Jatharia Canada Western Red Spring wheat

Abstract

AAC Jatharia (BW483) is a hollow-stemmed, high-protein, and high-yielding spring wheat (Triticum aestivum L.) for the longer growing season areas of the Canadian Prairies. AAC Jatharia was the highest yielding line in the Central Bread Wheat Cooperative (CBWC) Registration Tests performed in the eastern prairies in 2011, 2012, and 2013. Over 2 yr of testing (2011–2012), AAC Jatharia had grain yield 2.5% higher than Unity, 11.6% higher than 5603HR, 7.8% higher than McKenzie, and 19.2% higher than CDC Teal across all locations. In 2013, AAC Jatharia yielded 6.3% higher than Unity across all Manitoba and Saskatchewan locations. AAC Jatharia was resistant to leaf rust (Puccinia triticina Erikss.), and had intermediate resistance to stem rust (Puccinia graminis f. sp. tritici), stripe rust (Puccinia striiformis Westend), leaf spot complex, and Fusarium head blight (FHB) (Fusarium graminearum) infection, with lower FHB index and deoxynivalenol (DON) content compared with Unity. AAC Jatharia was resistant to infestation of the orange wheat blossom midge (Sitodiplosis mosellana Géhin) evaluated over 2 yr (2012 and 2013). It had higher kernel weight and test weight compared with all check cultivars, whereas its maturity was within the range of the check cultivars. AAC Jatharia is registered in the Canada Western Red Spring Wheat class for its premium quality attributes.
