应用花粉管通道法、种子浸渍法及孕穗期茎注射等方法，将玉米等外源供体DNA直接导入水稻品种中，其后代在生育期、株高、穗数、粒数及粒重等主要性状方面都产生了明显的变异。本文初步报道了用普通栽培水稻盐粳10号为受体，玉米黑307为供体将其DNA经孕穗期茎注射法导入后得到的变异株系及花粉管通道法、种子浸渍法后代的变异情况。
Application of pollen tube pathway, seed dipping method and booting injection at the booting stage, direct introduction of exogenous donor DNA into rice varieties, its offspring in the growth period, plant height, spike number, grain weight and grain weight Traits have produced a significant variation. In this paper, we report the variation of the mutant lines and pollen tube channels, and the seeds of seed dipping method, which were obtained by using common rice cultivar Yanjing 10 as the receptor and corn black 307 as the donor, Happening.
