Abstract:

Fifteen dual purpose barley genotypes were evaluated at ten major growing locations to estimate GxE by parametric and non-parametric measures. Highly significant differences among genotypes, environments and G x E interaction were observed. Wide variation seen genotypes average yield and G10, G12, and G4 were high yielder genotypes. Value of bi > 1 resulted for G12, G10, G11, G5, and G8 besides bi < 1 for G12. Measures W2i and σ2i pointed towards G15, G13, G6, G4 as desirable genotypes. GAI identified G10, G4, G13, G12 while Pi marked G12, G4, G13 genotypes with stable performance. Lower values of Environmental variance favored G15, G13, and G6. Coefficient of variation observed consistent performance of G15, G13, G9, G6. Si(1) and Si(2) measures marked G15, G13 genotypes whereas Si(3) and Si(6) found G15 followed by G13, G7 and G14 were stable performance. NPi(1) recognized G10 followed by G1 and G5 were stable as compared to other. NPi(2), NPi(3) and NPi(4), observed stable yield of G7 followed by G14, G9, and G15. Kang’s rank-sum measure indicated lower values for G13, G4, and G15. Non-parametric measures isolated G10, G1 and G2 for unstable yield realization. Significant positive correlation of yield with GAI, Pi & Kang’s rank-sum while negative with Si(3), Si(6), NPi(2), NPi(3), NPi(4). Positive relation maintained Si(s), among themselves. NPi(s) explained both type of relationships with each other. Biplot analysis based on first two principal components clustered measures of G x E into 3 major groups by. Larger group comprised of CVi, Kang, Si(1), Si(2), Wi 2 and 2i, while GAI along with Pi separated in other group. Ward’s method clustered Yield, GAI, Pi and Kang measures together. Non parametric NPi(2), NPi(3), NPi(4) bonded with Si(3), Si(6). Parametric measures of CVi, Wi2, s2i, S2xi joined hands with Si(1), Si(2).
