Abstract:
Genotype x environment interaction of wheat genotypes had been deciphered by AMMI, BLUP and Non parametric measures. Analysis revealed the highly significance of the G×E interaction which further bifurcated in seven interaction principal components accounted for 78.7% of total interaction variation. Measures (ASV1 and ASV) based on first two IPCAs recommended G1, G12, G9 and G12, G1, G14 genotypes respectively. MASV and MASV1 measures had been utilized seven significant IPCAs recommended G14, G1, G11 and G14, G11, G7 wheat genotypes for this zone respectively. BLUP-based measure, HMGV settled for G3, G8, G12 while RPGV measure favoured G3, G8, G4 and HMRPGV selected G3, G8, G4 genotypes. Non parametric composite measures NPi (1) observed suitability of G11, G1, G3 whereas NPi (2) selected G11, G1, G9 while NPi (3) identified G11, G1, G9 genotypes. Genotypes G11, G1, G9 were of choice by NPi (4). The biplot analysis of considered measures observed seven clusters. ASV joined hands with ASV1, IPC1, IPC3, IPC5 along with NPi (2) in one cluster. Mean yield formed cluster with HMGV, RPGV HMRPGV i.e. BLUP based measures.
