烟草种质资源分子标记与配合力遗传效应研究进展

Research progress on combining ability and molecular markers assisted of tobacco germplasm evaluation

综述了烟草种质资源分子标记与配合力遗传效应研究进展,并对存在问题进行了讨论,提出了:(1)在重视种质资源搜集、保存的同时,深化遗传资源鉴定与利用,发掘现有各类烟草种质资源有利基因和特异种质,拓展烟草遗传改良亲本的来源;(2)充分了解亲本之间的遗传差异,选配出强优势杂种组合,促进烟草杂种优势研究的发展;(3)加强DNA分子标记技术与烟草杂种优势利用的基础理论研究,拓展DNA分子标记技术在烟草上应用的广度和深度。

Progress on combining ability and molecular markers assisted tobacco germplasm evaluation was discussed. It indicated that： （1） Importance need to be attached to collecting and couserving germplasm, infensive identification and utilization of germplasm, identifying useful genes and special germplasm and broadening the origins of genetic cross parents of tobacco. （2） Understanding of inheritance difference, in order to promote the development of the tobacco heterosis. （3） Research on molecular marker technology and heterosis utilization of tobacco should be strengthened.
