Abstract:

AMMI analysis observed highly significant values of environments, GxE interaction effects and genotypes effects for both the years of study. Lower values of EV1 during (2016-17) ranked genotypes as  (G6, G2, G8); D1 for (G6, G2,  G8); values of ASTAB1 for (G6, G2, G8) while SIPC1 for (G7, G1, G5) genotypes.  EV2 measure pointed towards (G6, G2, G9) as desirable, D2 for (G6, G2, G8), whereas as per SIPC2 were (G5, G7, G8) & ASTAB2 opted for (G6, G2, G9). ASV and ASV1 recommended (G6, G2, G9) genotypes possessing stable performance as measures used 56.9% of GxE interaction. Ranked values of EV3 preferred G2, G6, G8; SIPC3 pointed towards G5, G8, G1; D3 identified G2, G6, G8 and ASTAB3 considered G2, G6, G8 wheat genotypes. Numerical values of D7 ranked G6, G2, G8; SIPC7 chosen G8, G1, G5. EV7 pointed towards G2, G6, G8 & ASTAB7 identified G9, G1, G4 as desirable over the studied environments. Composite measure MASV selected G6, G2, G9 & MASV1 cited as G6, G2, G8 would be desirable. Genotypes G8, G2 and G6 by Mean, GAI, HM, PRVG and MHPRVG measures would be of choice across environments of study. Biplot analysis of studied measures exhibited three major clusters and most of the measures clubbed in first cluster. Seven significant IPCA’s were used to calculate AMMI based measures during second year (2017-18) as accounted more than 96.6%.  Minimum values of EV1 ranked (G9, G6, G1), D1 pointed (G9, G6,  G1) , ASTAB1 for (G9, G6, G1) and for SIPC1 were (G7, G5, G10). EV2 pointed towards (G9, G1, G6) as desirable, for values of D2 genotypes were (G9, G1, G6) as per criterion of SIPC2 were (G7, G5, G10) & ASTAB2 favoured  (G9, G1, G6). ASV and ASV1 recommended (G9, G1, G6) as of stable performance. D7 expressed minimum values G9, G1, G6; SIPC7 observed G5, G9, G10, measure EV7 pointed towards G1, G5, G4. ASTAB7 identified G9, G1, G4 as desirable. Composite measure MASV selected G9, G5, G1 and MASV1 as G9, G1, G5 for desirable performance. Genotypes G8 G9 by Mean, G7, G4 by GAI & HM, G4, G10 by PRVG and G7, G4 by MHPRVG measures based on yield of genotypes across environments of study. Association analysis among AMMI measures and yield based analytic measures by multivariate hierarchical Ward’s clustering approach grouped into four major clusters. Largest group I clubbed  measures as MASV1, ASV, MASV, D2, D3, D7,  with  EV2, EV3, SIPC5, SIPC7, EV7. Group II contains ASTAB1, ASTAB2, ASTAB5, D1, D5, EV1, EV5, ASV1 whereas yield based measures exhibited close proximity and placed close to each other as in separate group.
