Grain yield performance of new wheat germplasm with resistance to Karnal bunt

An international research collaboration with CIMMYT (International Maize and Wheat Improvement Center, Mexico) has developed new wheat germplasm carrying Karnal bunt resistance genes. These will be made availableto Australian breeders for variety development. As a prerequisite, this study was carried out to determine what penalties could affect yield or its components due to incorporating Karnal bunt resistance.

与国际玉米小麦改良中心（International Maize and Wheat Improvement Center, Mexico，简称CIMMYT）开展的国际科研合作，已培育出携带卡尔纳耳黑穗病（Karnal bunt）抗病基因的小麦新种质。该种质将提供给澳大利亚育种者用于小麦品种选育。作为种质分发的前提条件，本研究旨在明确通过导入卡尔纳耳黑穗病抗病基因，可能对产量及其构成因子产生何种不利影响。
