摘要: 对选育的XN-1型紫花苜蓿及其原生质体再生植株的染色体核型进行对比分析。结果表明,原生质体再生植株与母株相比。染色体在长度、臂比、着丝粒指数等方面没有明显的差异,其核型均符合2n=4x=32=29m+3sm(SAT)。

Abstract: The chromosome karyotypes of the bred type XN-1 of alfalfa and its regenerated plantlet from protoplast were analyzed contrastively. The results showed that the chromosomes of regenerated plantlet from protoplast had no obvious difference from that of stock plant in the aspects of length, ann ratio and centromere index and their karyotypes accorded with 2n=4x=32=29m+3sm (SAT).
