摘要：为发掘利用孝顺竹在耐寒性和纤维品质方面的优良遗传基因,开展孝顺竹开花生物学特性和杂交试验研究。结果表明:孝顺竹花期较长,柱头可授性好,花粉生活力高,非常适宜作为杂交的亲本。孝顺竹×麻竹杂交后,以母本自交苗为对照,筛选出10株表型杂种,4个月龄时10株表型杂种的叶长、叶宽、叶长/宽、地径、发笋数、叶片形状、叶脉数、叶鞘高度、叶鞘繸毛、叶耳、叶舌等性状均介于母本自交子代与父本自交子代之间。AFLP标记分析表明:10株子代引入的父本特异位点占21.97%～28.10%,聚类分析显示10株杂种首先聚在一起,然后分别与父本和母本相聚。多数杂交子代在苗期表现出旺盛的生长势,15个月龄时杂种个体间秆箨刺毛性状呈现出较大的差别。
Bambusa multiplex（Gramineae,Bambusoideae） is a sympodial bamboo species with relatively strong cold-resistance and good fibre quality.In this paper we studied its flowering characteristics and cross breeding.The results showed that B.multiplex was a favorable parental line with long florescence,strong stigma and pollen vigor.A cross between B.multiplex and Dendrocalamus latiflorus was conducted and 10 putative hybrids were selected by morphological characteristics in comparison with the maternal selfed progenies.Those 10 putative hybrids at four months old exhibited middle values in leaf length,leaf width,leaf length/width,diameter,shoot number,leaf shape,leaf veins,height of leaf sheath,cilia in leaf sheath,leaf auricle,leaf ligule,etc between the paternal and maternal selfed progenies.There were 21.97%-28.10% paternal specific loci expressed in the 10 hybrids exposed by AFLP markers.Clustering analysis showed that the 10 hybrids were clustered together firstly and then grouped with their paternal and maternal parents.Most hybrids exhibited vigorous growth performance and cilia in culm sheath of each clone showed great difference at fifteen months old.
