Regional Experimental Analysis of Linum usitatissimum in Gansu Province based on BLUP and GGE Biplot
摘要
Abstract
To more accurately comprehensively evaluate the results of the Linum usitatissimum region-al trials and to select high-quality new Linum usitatissimum varieties,the original yield data were re-placed by the BLUP(Best Linear Unbiased Prediction)values.The GGE(Genetic Gain Evaluation)biplot was used to analyze the yield performance,stability,adaptability,as well as the discrimination ability and representativeness of the 16 participating varieties in the 2023-2024 Linum usitatissimum regional trials in Gansu Province.The results showed that after BLUP correction,the coefficient of variation of the yield data among varieties,among trials and among years was reduced.The results of variance analysis indicated that the BLUP values were significantly better at explaining the total varia-tion.The variety with the best yield performance was 2015-12-17.R619 and H228 had good stability.1234-16-1-1,EA-43,1189 and 2012-55-11 had both high yield performance and good stability.1219-6-1-1-1,P2010-7-1 and Longya 13(control)had relatively high yields but poor stability.1556,2015-11-13 and 1139 had relatively weak average yields and overall performance.Jingtai point had a relatively unique ecological nature and had strong selectivity for varieties.The other trials were mostly distribu-ted near the ideal environmental vector,which could provide certain discrimination ability and better represent the overall trial area.关键词
