摘要
对普通小麦{[(A)京引39A×75-3369]A2×806}A7×7269-10和小黑麦杂交后代的24个株系进行了农艺性状的调查和分析,发现在抗虫性、有效分蘖、生育期、株高和千粒重等性状上都表现了超亲的变异,增加了普通小麦常规育种的遗传资源,有利于进行新品系的选育。是一套具有筛选价值的远缘杂交后代株系。
Twenty four strains of the hybrid progeny of common wheat{A2×806}A7×7269-10 and triticale were studied and analyzed on their agronomic characters.Many variations were found superior to their parent in such straits as insect tolerance,effective tiller,growth season,plant height and 1000grain weight,which widened the genetic resources for traditional breeding of wheat.These materials were useful for the selection of new lines.They were a set of progeny of distant hybridizations of great selective value.
