青稞新品种(系)在共和地区的对比试验

Comparative Experiment of New Highland Barley Varieties(Strains)in Gonghe Area

为了丰富共和地区青稞后备种质资源,促进青稞产业发展。本研究以柴青1号(CK)为对照,引进5个青稞新品种(系),进行区域对比试验。结果表明:BQ15061-1、14YN-787参试品种,平均每公顷产量比CK都有所增加。从田间表现、经济性状、抗逆性、适应性来看,品种(系)14YN-787表现突出。在具备丰产的前提下,在共和地区适宜种植。14YN-787、BQ15061-1出现倒伏,一定程度上与年度降雨和气候变化有关,但对产量影响不大。

In order to enrich the reserve germplasm resources of highland barley in Gonghe area and promote the development of highland barley industry.In this study,Chai Qing No.1(CK)was used as the control,and five new highland barley varieties(strains)were introduced for regional comparative test.The results showed that the average yield per hectare of BQ15061-1 and 14YN-787 varieties increased compared with CK.From the field performance,economic characters,stress resistance and adaptability,the variety(strain)14YN-787 is outstanding.Under the premise of high yield,it is suitable to plant in Gonghe area.Lodging of 14YN-787 and BQ15061-1 is related to annual rainfall and climate change to some extent,but it has little effect on yield.
