Analysis of One-Year Multi-point Test Demonstration Result of New Strains of Spring Barley
In order to screen out new highland barley varieties(lines)with high yield,stable yield and strong resistance suitable for growth in Lhasa River Valley.'Sulaqing 3472'and'Sulaqing 3453'new spring barley varieties(lines)bred in Lhasa,were selected as experimental materials in this study.The multi-point adaptability,high yield and stability of new varieties(lines)in different ecological regions were studied in Lhasa River Valley.The results show that the yield of'Sulaqing 3453'and'Sulaqing 3472'were significantly higher than that of'control Zangqing 2000',by 8.80%and 11.06%,respectively,and the differences reached extremely significant level.Through the analysis of varieties(lines)yield and stabil-ity,'Sulaqing 3472'has the best comprehensive performance in the multi-point test of new spring highland barley strain,followed by'Sulaqing 3453'.The performance of'2000 Highland Barley'is general.The results indicated that the new spring highland barley strains'Sulaqing 3453'and'Sulaqing 3472'have strong adaptability.They can grow and mature normally in each experiment.At the same level of soil fertility,the yield was higher'than Zangqing 2000',which is suitable to regional test and demonstrate planting in Lhasa valley area.
