Grain Yield of Dual-Purpose Barley Genotypes Estimated by AMMI, BLUP and Non-Parametric measures after One Cut

Abstract

AMMI analysis evaluated the total variations in genotypic yield values across the environments and partied the total variations into various components to assess their significance. Environments, GxE interactions, and genotypes effects were highly significant with 69.4%, 24.1%, 3.4% respectively. IPCA-5 favored G11, G6, G8 as per IPCA-6 genotypes would be G5, G4, G17 while IPCA-7 pointed towards G3, G20, G4. First two AMMI components totalled 57.6% and ASV1 & ASV measures recommended (G4, G20, G15). MASV1 & MASV measures considered 98.5% total of seven Interaction principal components and identified G15, G9, G6 genotypes. G21, G17, G10 would be of consistent yield as per least values of standard deviation whereas CV identified G6, G10, G17 genotypes. Non parametric measures S i s selected G15, G13, G9 whereas non parametric composite measures selected G15,
