其中,种子千粒重变异最大;旗叶长度、花序形状次之;穗叶距、花药宽度、旗叶宽度等性状变异中等;而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性,花序直立、紧缩的鸭茅,叶片窄长,茎秆粗壮,旗叶较长,雄性生殖器官发育良好,结种性能强;而花序下垂、开展的鸭茅则与之相反。3聚类分析表明,不同野生鸭茅种源可划分为3类,其中花序下垂种源聚于一类;而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析,花序直立的鸭茅更具开发利用潜力。

Green fluorescent protein gene was conjugated to the 3 end of the PAP gene in order to screen easily of the transgenic cotton plants. The combined gene was cloned into plant expression vector pBI121 and then transformed. About 5000 seeds of the transgenic cotton were obtained and the some seedlings of the transgenic cotton could give a bright green fluorescence in the dark condition when the cotton seedlings were irradiated with ultraviolet rays. This result reflected that the GFP gene was expressed in the transgenic cotton; dot-blot result also demonstrated that PAP gene was exactly transformed into the cotton. The capacity of the Verticillium dahliae-resistance is being analyzed.
为了便于转基因棉花后代的筛选,在 PAP基因的 3'端融入了绿色荧光蛋白GFP)基因,然后将融合基因克隆在植物表达载体PBI 121上,再进行遗传转化,得转基因棉花种子5000余粒,将种子播种长到于叶展开时,先在黑暗中用紫外灯照射,查找表现绿色荧光的幼苗,然后再用地高辛标记的PAP基因特异性探针对这些棉花进行点杂交,最后发现有8株棉花表现阳性反应,说明PAP基因的确己经转到了棉花的基因组中,其棉花黄萎病的抗性鉴定正在进行之中。
