摘要
为丰富红掌品种新型花色、满足市场多元化需求,选育紫色红掌新品种。以Sensa为母本、White King为父本,经人工杂交、无菌播种、出苗、单株筛选、分子鉴定、组培扩繁和多点试验,选育出紫色红掌新品种。结果表明:选育出的紫色红掌新品种明农倾城常年开花、花期持久、抗病性强、适应性好,具有较高的观赏价值,在2020年7月获得农业农村部颁发的植物新品种权证书(品种权号:CNA20162141.4)。明农倾城株型中等、紧凑,生长势强,平均株高48.84 cm、冠幅82.82 cm;叶片绿色、有光泽、中等卵圆形;佛焰苞高于叶,紫色、有光泽、中等卵圆形;肉穗花序直立、深紫色。通过GBS-seq的SNP位点和进化树分析表明明农倾城与其亲本在分子水平上存在差异且亲缘关系接近。
In order to enrich the new type of flower color of Anthurium andraeanum varieties and meet the diversified market demand,a new variety of purple Anthurium andraeanum was bred.With Sensa as the female parent and White King as the male parent,a new variety of purple Anthurium andraeanum was bred by using the artificial hybridization,sterile seeding,seedling emergence,individual plant screening,molecular identification,tissue cultivation&expanding propagation and multipoint test.The results showed that Mingnong Qingcheng,the new variety of purple Anthurium andraeanum,had the characteristics of perennial flowering,long florescence,strong disease resistance,and good adaptability,with higher ornamental value.The variety was awarded the certificate of new plant variety right issued by the Ministry of Agriculture and Rural Affairs in July 2020(Variety Right Number:CNA20162141.4).Mingnong Qingcheng had medium&compact plant type and strong growth vigor,with the average plant height of 48.84 cm and the crown width of 82.82 cm.The leaves of Mingnong Qingcheng were moderate ovoid in shape with shiny green color.The spathes could be distinguished by shiny purple color with moderate ovoid in shape,and significantly positioned above the leaves.The spadixes were dark purple and upright.The SNP site and phylogenetic tree analysis of GBS-seq showed that there were differences at the molecular level between Mingnong Qingcheng and its parents and their genetic relationship was close.
