沙棘种质资源综合评价及利用

Studies on Comprehensive Evaluation and Application of Seabuckthorn Germplasm Resources

以黑龙江省自主创新沙棘种质资源和国外新品种为研究对象,通过调查沙棘生态及经济性状、建立决策指数评价法,对经济型和生态经济型沙棘进行综合评价和筛选利用研究,结果表明不同种质间的指标性状存在明显差异。经济性状综合评价排序是:绥棘2号、楚伊、绥棘3号、首都、芬兰、绥棘4号、MEZ14、绥棘1号、新俄3号、EZZ-4、小辣椒。绥棘2号以长果柄和无棘刺而排序第一,是典型的经济型沙棘品种。生态经济性状综合评价排序为:芬兰、EZZ-4、首都、绥棘2号、绥棘3号、MEZ-14、新俄3号、小辣椒、绥棘4号、楚伊、绥棘1号,其中芬兰、EZZ-4和首都排列前三,是典型的生态经济型沙棘品种。本研究为实际生产筛选出了适宜的栽培品种,绥棘2号、楚伊、绥棘3号等适宜作为经济型沙棘建园材料,芬兰、EZZ-4、首都等则作为生态经济型沙棘建园材料,同时又为新品种选育提供资源保障。

In order to study on comprehensive evaluation and application of the economic type and ecoeconomic type of seabuckthorn germplasm resources,a series of independent innovation germplasm resources and foreign varieties have been taken as experiment materials,through the survey of their ecological and economic traits,modeling the method of evaluation index decision. Experimental results indicated that there were significant differences among resources＇ characteristic index. In the evaluation of economic traits,the sort is‘Suiji 2＇,‘Chuyi＇,‘Suiji 3＇,‘Shoudu＇,‘Fenlan＇,‘Suiji 4＇,‘MEZ-14＇,‘Suiji 1＇,‘Xine 3＇,‘EZZ-4＇,‘Xiaolajiao＇.‘Suiji 2＇was the best one by virtue of the stalk length and the number of thorn,‘Suiji 2＇was the typical economic type variety.‘Suiji 3＇,‘Fenlan＇,‘Shoudu＇were inferior to‘Suiji 2＇because of the thorns,the yield and the stalk. In the evaluation of eco-economic traits,the sort is‘Fenlan＇,‘EZZ-4＇,‘Shoudu＇,‘Suiji 2＇,‘Suiji 3＇,‘MEZ-14＇,‘Xine 3＇,‘Xiaolajiao＇,‘Suiji 4＇,‘Chuyi＇,‘Suiji 1＇.‘Fenlan＇,‘EZZ-4＇,and‘Shoudu＇arranged in the top three,the height of plant and the crown diameter were significantly better than others. They were the typical eco-economic type varieties,this study selected the suitable cultivars for practical production,‘Suiji 2＇,‘Chuyi＇‘Suiji 3＇et al were suitable to orchard materials of economic type,‘Fenlan＇,‘EZZ-4＇,‘Shoudu＇et al were suitable to orchard materials of eco-economic type. Meantime,they all provided the resources supports for the new variety breeding.
