Abstract

AMMI analysis for grains per head had highlighted highly significant variations due to locations, T×L interactions and treatments, with 73.9%, 12.2% and 3.6% respectively. First interaction AMMI factor contributed 48.9% whereas AMMI2, AMMI3, AMMI4 accounted for 22.2%, 13.1%, 6.1% respectively. Number of ear heads per m2 observed First two significant components accounted for 67.8% whereas the total contributions of significant components were 93.7%. While 70.3% and 29.7% of total T×L sums of squares were for signal and noise. AMMI based measures while considering only 71.2% T×L interaction sum of squares recommended (T7, T6, T8) as of stable performance for grains per ear head. Adaptability measures MASV and MASV1 used 93.7% of T×L interactions sum of squares had settled for T6, T8, T7 treatments for. Superiority index measures for grains per ear heads considered value and stable performance in 65 and 35 ratios in weighted average found utility of T6, T5, T12 treatments. Adaptability measures for number of ear heads per m2 pointed towards T3, T2, T4 treatments. Biplot analysis had found tight positive relationship among AMMI based measures with W1, W2, W3, W4, W5, W6, WAASB values. Analytic adaptability measures PRVG, HMPRVG, PRVGu, HMPRVGu expressed strong bondage with measures of central tendency mean, GAI, HM for grains per par heads. Clustering pattern among measures expressed superiority index measures irrespective of BLUE and BLUP estimates formed a cluster and placed with cluster of analytic adaptability measures number of ear heads per in the present study.

Conclusion

AMMI analysis had highlighted highly significant variations due to locations, T×L interactions and treatments effects. AMMI based measures recommended (T7, T6, T8) as of stable performance for grains per ear head. Adaptability measures MASV and MASV1 had settled for T6, T8, T7 treatments for number of ear heads per m2. Superiority index measures as weighted average of trait value and stable performance in 65 and 35 ratios in found utility of T6, T5, T12 treatments. Biplot analysis had found tight positive relationship among AMMI based measures with W1, W2, W3, W4, W5, W6, WAASB values.
