普通小麦与小黑麦杂交后代农艺性状分析

Analysis of Agronomic Characters of Common Wheat × Triticale Progeny

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{A2×806}A7×7269-10 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 1000grain 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.
